What constitutes access to FP? Current human rights-based contraceptive guidelines indicate that access begins as soon as women or couples express a desire to avoid pregnancy and their risk of unintended pregnancy is established. However, few studies have sought to define and measure cognitive and psychosocial access to contraception. To propose a comprehensive framework for the cognitive and psychosocial accessibility of contraception, we critically analyzed the literature on attitudes toward FP. The main dimensions that emerged were knowledge about FP, fear of side effects, approval of contraception, and contraceptive agency. We then identified and adjusted some questions that can capture these dimensions more comprehensively. As a result, we developed a questionnaire module comprising 15 questions, which was integrated into the 6th round of the PMA2020 survey in Burkina Faso in 2019. This research highlighted that previous studies have collected separate dimensions of contraceptive access, and the psychosocial dimension tended to be neglected. Our results demonstrate that it is possible to collect comprehensive data on cognitive and psychosocial dimensions of access to family planning.展开更多

The aim of the study is to determine the impact of female contraception on uterine vascularisation and the endometrium. Method: It was a descriptive comparative study with an analytical aim. It took place at the University Clinic of Obstetrics Gynaecology and the Radiology and Medical imaging Department of Sylvanus Olympio University Hospital in Lomé over a two-month period from May 15, 2023 to July 15, 2023. Group 1 included women using a modern contraceptive method and group 2 women not using a modern contraceptive method. Epidata 3.1 and R 4.0.4 software were used to process the data. Results: Each group included 50 women. There were no significant differences in uterine and endometrial biometrics. All women on contraception had their zone 1 vascularized, without vascularisation of zone 2, without significant difference with women without contraception The pulsatility index was greater than 3 in 51% (n = 51) of women, including 62.7% (n = 32) of women without contraception and 37.3% (n = 19) of women on contraception, with a statistically significant difference (p = 0.009). Conclusion: Contraceptive methods do not influence the biometry of the uterus. However, uterine artery Doppler indices can predict abnormal uterine bleeding.展开更多

The present study aims to identify the determinants of postpartum contraceptive use in a first level health facility. Methodology: This was a 6-month cross-sectional study conducted at the Urban Health Center of Castors. Postpartum women who presented within 42 days of delivery and who had a live child were included after informed consent. Results: Of 318 women enrolled during the study period, 106 were currently using a modern contraceptive method, for a prevalence of 33.3%. The mean age of the women was 25.3 years (±3.6), with extremes of 14 and 49 years. The age group [20 to 29] was the most represented with 52.8%. More than half of the women were in couples (54.7%) and had completed secondary education (53.8%). These women were mostly students (42.5%) and primiparous or pauciparous (70.7%). The most used contraceptive method was injectables (depot medroxyprogesterone acetate) (43.4%), followed by male condoms (23.6%) and oral contraceptives (17.9%). The unmet need for contraception was 40.6%. The main reasons for non-use were the desire to have more children (41.5%), fear of side effects (34.9%) and spousal opposition (12.3%). Factors associated with contraceptive non-use were educational level, occupation and parity. Conclusions: The rate of modern contraceptive use in the postpartum period is low in the study population. Interventions to increase the use of effective contraceptive methods are needed, especially among young women.展开更多

Population and Methods: This was a retrospective descriptive study, conducted from April 1st 2017 to January 31st 2022 in the Obstetrics and Gynecology Department of the University Hospital of Brazzaville, including women aged 35 years and over who had received a contraceptive method. The study variables were sociodemographic, reproductive, clinical and contraceptive method related. Results: Two hundred and thirty customers were collected during the study period, i.e., 10.8% of the patients who received contraception. They were 38.4 ± 3 years old on average, had secondary education (46.1%), were of low socioeconomic status (54.3%), lived with a partner (98.7%) and came from an urban area (97.4%). They were multigravida (85.2%), and multiparous (63.9%) with an average of 4 living children. The indications were of two types: convenience (26.2%) and medical (73.8%). The most commonly used contraceptives were implants (72.2%) and injectable progestin (20.5%). Conclusion: The indication for contraception for women over 35 years of age at the University Hospital Center of Brazzaville is more medical, with the use of long-acting contraceptives.展开更多

METHODS： MEDLINE, PubMed and Google Scholar were searched for randomized controlled trials and prospective cohort studies of IUD insertions at different times during the postpartum period. Time of insertion during the postpartum period was documented speci-fically, immediate post placenta period （within 10 min）, early post placenta period （10 min to 72 h）, and de-layed/interval period （greater than 6 wk）. Other study variables included mode of delivery, vaginal vs cesarean, manual vs use of ring forceps to insert the IUD. RESULTS： IUD insertion in the immediate postpartum （within 10 min of placental delivery）, early postpartum （10 min up to 72 h） and Interval/Delayed （6 wk onward） were found to be safe and effcacious. Expulsion rates were found to be highest in the immediate postpartum groups ranging from 14% to 27%. Immediate post placental insertion found to have expulsion rates that ranged from 3.6% to 16.2%. Expulsion rate was significantly higher after insertion following vaginal vs cesarean delivery. The rates of infection, perforation and unplanned pregnancy following postpartum IUD insertion are low. Method of insertion such as with ring forceps, by hand, or another placement method unique to the type of IUD did not show any signifcant difference in expulsion rates. Uterine perforations are highest in the delayed/interval IUD insertion groups.Breastfeeding duration and infant development are not affected by delayed/interval insertion of the non-hormonal （copper） IUD or the Levonorgestrel IUD. Timing of the Levonorgestrel IUD insertion may affect breastfeeding. CONCLUSION： IUD insertion is safe and efficacious during the immediate postpartum, early postpartum and delayed postpartum periods. Expulsion rates are highest after vaginal delivery and when inserted during the immediate postpartum period. IUD associated infection rates were not increased by insertion during the postpartum period over interval insertion rates. There is no evidence that breastfeeding is negatively affected by postpartum insertion of copper or hormone-secreting IUD. Although perforation rates were higher when inserted after lactation was initiated. Randomized controlled trials are needed to further elucidate the consequence of lactation on postpartum insertion. Despite the concerns regarding expulsion, perforation and breastfeeding, current evidence indicates that a favorable risk beneft ratio in support of postpartum IUD insertion. This may be particularly relevant for women for whom barriers exist in achieving desired pregnancy spacing.展开更多

There are growing disparities in maternal health between indigent, minority women and Caucasian women of higher socioeconomic status. Family planning has long been viewed as a solution to these problems. As reliance on permanent contraception has diminished, timely access to highly effective contraceptive methods, namely long acting reversible contraceptives, which includes the contraceptive hormonal implant and intrauterine device- has become even more important. For women in the United States and abroad, the time of delivery is the one reliable opportunity for women to receive medical care. Consistently, research has shown that providing contraception in the immediate postpartum period is safe, effective, feasible and cost effective. However, misperceptions, lack of supplies, and reimbursement issues combine to defeat attempts to provide the most effective methods of contraception during that hospitalization. We believe that it is time to tackle the problem of unintended and rapid repeat pregnancy using an evidence-based, patient-centered paradigm and to eradicate systemic barriers blocking access to contraceptive methods during hospital stay. This editorial will outline some of the more compelling evidence supporting this move and will provide insights from successful programs.展开更多

The only ef-fective technique available for male contraception is vasectomy, being practiced world wide, despite that it is a perma-nent surgical procedure and its successful reversal is not assured. Although no-scalpel vasectomy minimizes surgicalprocedures, the fate of its reversal is akin to that of vasectomy. Several occlusive and non-occlusive vasal procedureswhich claim to be reversible without surgical intervention, possess more disadvantages than advantages. Vas occlusionwith plug, ' Shug' or medical grade silicone rubber, although claimed to produce reversible azoospermia without affect-ing spermatogenesis, requires skilled microsurgery for their implantation and later removal. RISUG^R, a non-scleroticpolymer styrene maleic anhydride (SMA), could be more advantageous than vasectomy and other vas occlusive proce-dures in that it could be a totally non-invasive procedure by 'no-scalpel injection' and 'non-invasive reversal'. It isclaimed to offer long-term contraception without adverse side effects and also to be possible as a male spacing methodby repeated vas occlusion and non-invasive reversal. The drug is currently under multicentre Phase Ⅲ clinical trial.展开更多

Design: Review of basic and clinical research over 30 years. Setting: Task force of a multinational agency and collaborating agencies. Conclusion(s): Through the involvement of many international scientists, the WHO Task Force has uniquely contributed to the exploratory phases of the research in male contraception and by its multicenter contraceptive efficacy studies has accelerated progress towards the ideal hormonal method. Despite an adverse climate involving social and political attitudes, funding constraints, and pharmaceutical industry hesitations, WHO formed coalitions with governments and international agencies to sustain research with results that apply to men in culturally diverse populations and thereby to influence activities across the whole range of global reproductive health and family planning.展开更多

The latter approach holds promise for mankind ashuman sperm are susceptible to glycolytic inhibition. Future contraceptive developments may arise from production oftargeted inhibitors, research on the displacement of sperm proteins in the epididymis and interference with sperm plasmamembrane ion channels.展开更多

Methods: The 16 Chinese volunteers treated were divided into two groups in regard to the sperm count during the treatment period, 7 men in the responder group (Group R), including 6 azoospermia and one severe oligozoospermia, and the remaining 9 in the non-responder group (Group N), including 4 oligozoospermia and 5 with sperm counts greater than 20×106/mL. The differences in serum profiles of FSH, LH, T, LNG and T/LH ratio were compared between the two groups and the correlation between the seminal fluid parameters and serum reproductive hormones was analyzed. Results: The serum FSH level was lower in Group R than that in Group N (P<0.05), while the serum LH and LNG levels were higher in Group R than those in Group N (P<0.05). The sperm density (P<0.01, r=0.235), motility (P<0.01, r=0.326) and vitality (P<0.01, r=0.219) showed significantly positive correlation with the serum FSH level. Conclusion: The blood LNG and T levels, the degree of FSH inhibition and/or the sensitivity of the pituitary-testis axis to exogenous steroids, as well as the individual spermatogenetic potential and the functional status of the Leydig cells may be factors bringing about individual differences in spermatogenic suppression in Chinese men treated with LNG and TU.展开更多

In the crrrent communication, we review 3 recently de-veloped methods applied for male contraception: testicular suspension, polyester-induced azoospermia and prolactin in-jection. The testicle was suspended in the superficial inguinal pouch close to the scrotal neck using 2 methods: stitchand ball. The azoospermic effect of the polyester sling seems to be due to 1) creation of electrostatic field across theintrascrotal structures, and 2) disordered thermoregulation. Prolactin administration, as a contraceptive method is effi-cient and safe and has the potential to be developed as a male contraceptive. The effect of the above mentioned 3methods is reversible. These methods, especially testicular suspension and polyester suspensors, are simple and easilyapplicable and were well acceptable by the subjects. (Asian J Androl 1999 Dec; 1: 161 - 167)展开更多

Methods Cross-sectional questionnaire study was performed on 383 female undergraduates in Nigeria in June 2006. Data analysis was with Z-square test and logistic regressions （P 〈O. 05）. Results One hundred and five （48.2%） had been sexually exposed. Only 32 （30.5%） used regular contraception. Seventy-three （24.3%）female undergraduates were aware of EC. Only 29 （7.6%） had used EC before. Most would not use emergency contraceptive drugs in future due to lack of awareness （64.8%）, and fear for future fertility and of drugs being injurious to health. Use of EC was associated with awareness of correct interval for use （OR=9.1; 95%CI： 2.1-39.9）. Conclusion There is poor knowledge about EC and poor use, while significant need remains. Most knowledge was acquired from peers and inaccurate. Peer educators are important and professionals＇ knowledge needs improvement.展开更多

Methods： A nested case-control study was conducted, involving 43 subjects, who did not achieve azoospermia or severe oligozoospermia when given monthly injections of 500 mg testosterone undecanoate （TU）, defined as partial suppressors compared with 855 subjects who had suppressed spermatogenesis （complete suppressors）. Sperm density, serum testosterone, luteinizing hormone （LH） and follicle stimulating hormone （FSH） concentrations at the baseline and the suppression phase were compared between partial and complete suppressors. Polymorphisms of androgen receptor （AR） and three single nucleotide variants and their haplotypes of FSH receptor （FSHR） genes determined by polymerase chain reaction （PCR） and DNA sequencing technique were compared between 29 partial and 34 complete suppressors. Results： Baseline serum LH level was higher and serum LH as well as FSH level during the suppression phase was less suppressed in partial suppressors. Additionally, in a logistic regression analysis larger testis volume, higher serum FSH concentrations alone, or interaction of serum LH, FSH, testosterone and sperm concentrations were associated with degree of suppression. The distribution of polymorphisms of AR or FSH receptor genes did not differ between partial and complete suppressors. In cases with incomplete FSH suppression （FSH 〉 0.2 IU/L）, the chances of reaching azoospermia were 1.5 times higher in the subjects with more than 22 CAG triplet repeats. Conclusion： Partial suppression of spermatogenesis induced by 500 mg TU monthly injections is weakly influenced by hormonal and clinical features but not polymorphism in AR and FSHR genes.展开更多

Recent work in our laboratory has shown that this protein is also expressed by developing germcells indicating a role of this protein in spermatogenesis. In view of the fact that the CFTR gene has a far reaching andwidespread effect on human reproduction, understanding the role of CFTR in the male reproductive tissues and its inter-vention by pharmacological agents can open a new avenue of research into the development of novel male contracep-tives.

Hence, this study assessed the level of knowledge and utilization of emergency contraception among undergraduate regular female students of Hawassa University, south Ethiopia. Methods: An institution-based cross-sectional survey was conducted among female students of Hawassa University in December 2012. Seven hundred seventy six of the students were sampled by using multistage sampling technique. Pretested structured questionnaire was used to collect the data. Results: The majority 719 (92.7%) of female university students ever had sexual intercourse and 17 (2.2%) experienced forced sex. Eight (47%) of these 17 students experienced unintended pregnancy all of which resulted in an induced abortion. Three hundred seventy nine (72.2%) of the respondents had knowledge about emergency contraceptives and only 41 (10.8%) of them had ever used emergency contraceptives;oral contraceptive pills were the most widely used form of all emergency contraceptives 41 (10.8%). Age, marital status and age at menarche were associated with knowledge of emergency contraception;moreover, residence, year of study and experience of forced sex were found to be predictors of emergency contraception utilization. Conclusion: Female university students had been experiencing high rate of unintended sexual practice and pregnancy, low knowledge level and utilization of emergency contraceptives;moreover, they had no youth-friendly access to the services. Therefore, there is a need for collaborated effort to improve service access and scale up their utilization level to prevent unwanted pregnancy.展开更多

Current family planning services predominantly target a female clientele with few significant developments in malefertility regulation for over a century. The last two decades have witnessed a gathering interest, initially from the scien-tific community, and laterally from industry, in the development of safe, reliable, reversible methods of contraceptionfor men. This review summarises the methods of male fertility regulation which are currently available and critically ex-amines the published data on novel developments in male hormonal contraception which offer the potential of improvedcontraceptive choice for all in new millennium.

Although perforation rates were higher when inserted after lactation was initiated. Randomized controlled trials are needed to further elucidate the consequence of lactation on postpartum insertion. Despite the concerns regarding expulsion, perforation and breastfeeding, current evidence indicates that a favorable risk beneft ratio in support of postpartum IUD insertion. This may be particularly relevant for women for whom barriers exist in achieving desired pregnancy spacing.
文摘In the United States, maternal mortality and unintended pregnancy rates are increasing. There are growing disparities in maternal health between indigent, minority women and Caucasian women of higher socioeconomic status. Family planning has long been viewed as a solution to these problems. As reliance on permanent contraception has diminished, timely access to highly effective contraceptive methods, namely long acting reversible contraceptives, which includes the contraceptive hormonal implant and intrauterine device- has become even more important. For women in the United States and abroad, the time of delivery is the one reliable opportunity for women to receive medical care. Consistently, research has shown that providing contraception in the immediate postpartum period is safe, effective, feasible and cost effective. However, misperceptions, lack of supplies, and reimbursement issues combine to defeat attempts to provide the most effective methods of contraception during that hospitalization. We believe that it is time to tackle the problem of unintended and rapid repeat pregnancy using an evidence-based, patient-centered paradigm and to eradicate systemic barriers blocking access to contraceptive methods during hospital stay. This editorial will outline some of the more compelling evidence supporting this move and will provide insights from successful programs.
文摘The vas deferens is a site which can be exploited for male contraception without undue side effects. The only ef-fective technique available for male contraception is vasectomy, being practiced world wide, despite that it is a perma-nent surgical procedure and its successful reversal is not assured. Although no-scalpel vasectomy minimizes surgicalprocedures, the fate of its reversal is akin to that of vasectomy. Several occlusive and non-occlusive vasal procedureswhich claim to be reversible without surgical intervention, possess more disadvantages than advantages. Vas occlusionwith plug, ' Shug' or medical grade silicone rubber, although claimed to produce reversible azoospermia without affect-ing spermatogenesis, requires skilled microsurgery for their implantation and later removal. RISUG^R, a non-scleroticpolymer styrene maleic anhydride (SMA), could be more advantageous than vasectomy and other vas occlusive proce-dures in that it could be a totally non-invasive procedure by 'no-scalpel injection' and 'non-invasive reversal'. It isclaimed to offer long-term contraception without adverse side effects and also to be possible as a male spacing methodby repeated vas occlusion and non-invasive reversal. The drug is currently under multicentre Phase Ⅲ clinical trial.
文摘Objective: To give an historical record of the research of the World Health Organization (WHO) Task Force to develop methods of male contraception; to examine the social, political, medical, pharmaceutical, funding, and other factors that influenced progress; and to suggest reasons why such methods are only now becoming available. Design: Review of basic and clinical research over 30 years. Setting: Task force of a multinational agency and collaborating agencies. Conclusion(s): Through the involvement of many international scientists, the WHO Task Force has uniquely contributed to the exploratory phases of the research in male contraception and by its multicenter contraceptive efficacy studies has accelerated progress towards the ideal hormonal method. Despite an adverse climate involving social and political attitudes, funding constraints, and pharmaceutical industry hesitations, WHO formed coalitions with governments and international agencies to sustain research with results that apply to men in culturally diverse populations and thereby to influence activities across the whole range of global reproductive health and family planning.
文摘The induction of infertility in males of several species through epididymal interference is more difficult to achieveby reduction of the mounts of epididymal secretions (eg α-glucosidase, L-carnitine) or immunological interferencewith secreted proteins ( eg D/E, P34H, P26h) than by direct actions of drugs on sperm function (eg inhibition ofglyceraldehyde 3-phosphate dehydrogenase by chloro-compounds). The latter approach holds promise for mankind ashuman sperm are susceptible to glycolytic inhibition. Future contraceptive developments may arise from production oftargeted inhibitors, research on the displacement of sperm proteins in the epididymis and interference with sperm plasmamembrane ion channels.
文摘Aim: To explore the causes of the difference in spermatogenic suppression between responders and non-responders in Chinese men treated with levonorgestrel (LNG) implants plus testosterone undecanoate (TU) injectable. Methods: The 16 Chinese volunteers treated were divided into two groups in regard to the sperm count during the treatment period, 7 men in the responder group (Group R), including 6 azoospermia and one severe oligozoospermia, and the remaining 9 in the non-responder group (Group N), including 4 oligozoospermia and 5 with sperm counts greater than 20×106/mL. The differences in serum profiles of FSH, LH, T, LNG and T/LH ratio were compared between the two groups and the correlation between the seminal fluid parameters and serum reproductive hormones was analyzed. Results: The serum FSH level was lower in Group R than that in Group N (P<0.05), while the serum LH and LNG levels were higher in Group R than those in Group N (P<0.05). The sperm density (P<0.01, r=0.235), motility (P<0.01, r=0.326) and vitality (P<0.01, r=0.219) showed significantly positive correlation with the serum FSH level. Conclusion: The blood LNG and T levels, the degree of FSH inhibition and/or the sensitivity of the pituitary-testis axis to exogenous steroids, as well as the individual spermatogenetic potential and the functional status of the Leydig cells may be factors bringing about individual differences in spermatogenic suppression in Chinese men treated with LNG and TU.
文摘The methods devised for male contraception are meagre. In the crrrent communication, we review 3 recently de-veloped methods applied for male contraception: testicular suspension, polyester-induced azoospermia and prolactin in-jection. The testicle was suspended in the superficial inguinal pouch close to the scrotal neck using 2 methods: stitchand ball. The azoospermic effect of the polyester sling seems to be due to 1) creation of electrostatic field across theintrascrotal structures, and 2) disordered thermoregulation. Prolactin administration, as a contraceptive method is effi-cient and safe and has the potential to be developed as a male contraceptive. The effect of the above mentioned 3methods is reversible. These methods, especially testicular suspension and polyester suspensors, are simple and easilyapplicable and were well acceptable by the subjects. (Asian J Androl 1999 Dec; 1: 161 - 167)
文摘Objective To assess perception and level of proper utilization of emergency contraception （EC） among female undergraduates. Methods Cross-sectional questionnaire study was performed on 383 female undergraduates in Nigeria in June 2006. Data analysis was with Z-square test and logistic regressions （P 〈O. 05）. Results One hundred and five （48.2%） had been sexually exposed. Only 32 （30.5%） used regular contraception. Seventy-three （24.3%）female undergraduates were aware of EC. Only 29 （7.6%） had used EC before. Most would not use emergency contraceptive drugs in future due to lack of awareness （64.8%）, and fear for future fertility and of drugs being injurious to health. Use of EC was associated with awareness of correct interval for use （OR=9.1; 95%CI： 2.1-39.9）. Conclusion There is poor knowledge about EC and poor use, while significant need remains. Most knowledge was acquired from peers and inaccurate. Peer educators are important and professionals＇ knowledge needs improvement.
文摘Aim： To analyze factors influencing the efficacy of hormonal suppression of spermatogenesis for male contraception. Methods： A nested case-control study was conducted, involving 43 subjects, who did not achieve azoospermia or severe oligozoospermia when given monthly injections of 500 mg testosterone undecanoate （TU）, defined as partial suppressors compared with 855 subjects who had suppressed spermatogenesis （complete suppressors）. Sperm density, serum testosterone, luteinizing hormone （LH） and follicle stimulating hormone （FSH） concentrations at the baseline and the suppression phase were compared between partial and complete suppressors. Polymorphisms of androgen receptor （AR） and three single nucleotide variants and their haplotypes of FSH receptor （FSHR） genes determined by polymerase chain reaction （PCR） and DNA sequencing technique were compared between 29 partial and 34 complete suppressors. Results： Baseline serum LH level was higher and serum LH as well as FSH level during the suppression phase was less suppressed in partial suppressors. Additionally, in a logistic regression analysis larger testis volume, higher serum FSH concentrations alone, or interaction of serum LH, FSH, testosterone and sperm concentrations were associated with degree of suppression. The distribution of polymorphisms of AR or FSH receptor genes did not differ between partial and complete suppressors. In cases with incomplete FSH suppression （FSH 〉 0.2 IU/L）, the chances of reaching azoospermia were 1.5 times higher in the subjects with more than 22 CAG triplet repeats. Conclusion： Partial suppression of spermatogenesis induced by 500 mg TU monthly injections is weakly influenced by hormonal and clinical features but not polymorphism in AR and FSHR genes.
文摘The cystic fibrosis transmembrane conductance regulator (CFIR) or the small conductance cAMP-activated chlo-ride channel encoded by the CFTR gene has been shown to play an important role in the formation of the epididymalfluid microenvironment. Recent work in our laboratory has shown that this protein is also expressed by developing germcells indicating a role of this protein in spermatogenesis. In view of the fact that the CFTR gene has a far reaching andwidespread effect on human reproduction, understanding the role of CFTR in the male reproductive tissues and its inter-vention by pharmacological agents can open a new avenue of research into the development of novel male contracep-tives.

文摘Objective:To investigate the contraceptive effect of intratesticular injection of chlorhexidine gluconate in dogs and compare it with that of zinc gluconate neutralized with arginine.Methods:Twenty-four sexually mature male mongrel dogs were randomly divided by replicate into four groups(n=6 per group).GroupⅡreceived intra-testicular injection of 2 mL zinc gluconate(10 mg/mL)neutralized with arginine.GroupⅡreceived intratesticular injection of 2 mL chlorhexidine gluconate(5%w/v).GroupⅢreceived intratesticular injection of 2 mL chlorhexidine gluconate(4%w/v).GroupⅣdid not receive any treatment and served as the control group.Testicular morphometry was conducted on day 0,7,15 and 30 after treatment.Semen was collected and evaluated on day 0 and 30.Data were analyzed using repeated measures analysis of variance.Results:There was no difference in the mean values of various parameters between dogs treated with zinc gluconate and those treated with chlorhexidine gluconate at any of the time points.In dogs treated with zinc gluconate or chlorhexidine gluconate,there was a significant increase in the testicular morphometric parameters on day 7 followed by a significant reduction thereafter(day 15 and 30).In contrast,there was no change in any of the parameters in the control untreated dogs during the course of the study.Compared to the pre-treatment values,the mean scrotal circumference and the mean paired testicular volume and testicular weight on day 30 were significantly lower in the treated dogs.Semen samples collected on day 30 from treated dogs were found to be azoospermic,whereas no change in semen quality was observed in the control untreated dogs.Conclusions:Intratesticular injection of chlorhexidine gluconate(5%w/v and 4%w/v)is equally as effective as zinc gluconate neutralized with arginine for chemical contraception in dogs.
文摘Introduction: Emergency contraception is used as an emergency procedure to prevent unintended pregnancy secondary to an unprotected se xual intercourse and method failure. Hence, this study assessed the level of knowledge and utilization of emergency contraception among undergraduate regular female students of Hawassa University, south Ethiopia. Methods: An institution-based cross-sectional survey was conducted among female students of Hawassa University in December 2012. Seven hundred seventy six of the students were sampled by using multistage sampling technique. Pretested structured questionnaire was used to collect the data. Results: The majority 719 (92.7%) of female university students ever had sexual intercourse and 17 (2.2%) experienced forced sex. Eight (47%) of these 17 students experienced unintended pregnancy all of which resulted in an induced abortion. Three hundred seventy nine (72.2%) of the respondents had knowledge about emergency contraceptives and only 41 (10.8%) of them had ever used emergency contraceptives;oral contraceptive pills were the most widely used form of all emergency contraceptives 41 (10.8%). Age, marital status and age at menarche were associated with knowledge of emergency contraception;moreover, residence, year of study and experience of forced sex were found to be predictors of emergency contraception utilization. Conclusion: Female university students had been experiencing high rate of unintended sexual practice and pregnancy, low knowledge level and utilization of emergency contraceptives;moreover, they had no youth-friendly access to the services. Therefore, there is a need for collaborated effort to improve service access and scale up their utilization level to prevent unwanted pregnancy.

文摘Effective regulation of human fertility has global consequences in terms of resource depletion, pollution and pover-ty. Current family planning services predominantly target a female clientele with few significant developments in malefertility regulation for over a century. The last two decades have witnessed a gathering interest, initially from the scien-tific community, and laterally from industry, in the development of safe, reliable, reversible methods of contraceptionfor men. This review summarises the methods of male fertility regulation which are currently available and critically ex-amines the published data on novel developments in male hormonal contraception which offer the potential of improvedcontraceptive choice for all in new millennium.
