“…The interval between vasectomy and late fertilization has ranged from eight months to ten years in the cases reported. [1][2][3][4] Since fertilization occurred without positive semen analysis, it may be speculated that vas deferens permeability for spermatozoa was intermittent, as has already been suggested. 3 The resulting risk of conception must not be underestimated.…”

“…3 In the United States, 56% of the doctors require one, 39% require two and 5% ask for three semen examinations after vasectomy in order to confi rm azoospermia. 2 The risk of delayed recanalization is small and has been estimated to be as low as one in 2000 to 7000 patients. 1 Late recanalization, shown by the presence of spermatozoa in the semen analysis after a previous negative result, has been found in 0.6 to 1%, although without resulting in pregnancy.…”

CONTEXT: The risk of paternity after vasectomy is rare but still exists. Overall failure to achieve sterility after vasectomy occurs in 0.2 to 5.3% of patients due to technical failure or recanalization. The objective of this report was to describe a rare but notable case of proven paternity in which the semen analyses had not given evidence of spermatozoa. CASE REPORT: A 44-year-old vasectomized man whose semen analyses had shown azoospermia became a father four years after sterilization. Blood sample DNA analysis on the child and husband proved biological paternity. Vasectomy may fail in the long run even without spermatozoa in semen analysis. The patient must be aware of this possibility.

“…17 Most agree that a single azoospermic semen sample is sufficient to deem the vasectomy effective. 18,19 However, because spermatozoa are detected in 10% to 40% of the 3-month post-vasectomy samples (the percentage depends on the vasectomy technique and the accuracy of the semen analysis), it may be necessary for up to 40% of the men to submit a second semen sample.…”

“…Surgically, vasectomy is performed in two separate steps: exposing some portions of the vas deferens out of the scrotum a step known as isolation, and in the next step, occluding the vas. The other method of performing vasectomy is the No-scalpel vasectomy (NSV) technique, it is used in the isolation of the vas deferens in the United States, it is becoming an increasingly popular method among physicians also a choice for the developing countries (10)(11)(12)(13)(14). The notable advantages includes a lower risk of hematomas, less bleeding and pain, lower risk of infections and less operating time (11)(12)(13).…”

Background: Traditionally, majority of the family planning services and campaigns focus on women without much consideration given to their male partners. In our society, there is bias, myth and misconception about vasectomy, this has resulted in a significant reduction in the willingness of men to seek vasectomy as a means of family planning. This study aims to identify the level of awareness and acceptance of male sterilization among men in Ogbomoso, south west Nigeria. Methods:This study was a cross sectional survey carried out among men in Ogbomoso, participation was voluntary and three hundred men had the questionnaires complete and suitable for analysis.Result: This study revealed a high level of awareness of family planning methods among men in Ogbomoso. However, less than half of these men agreed that men should be involved in family planning despite a higher number of the respondents being aware of vasectomy as a means of contraception. The common reasons for not accepting of vasectomy varied from preference for other methods of contraception, cultural taboos, religious sentiments, similarity to castration , fear for surgery and surgical complications. Conclusion:Renewed effort has to be made which will be aimed at improving the level of information about vasectomy in the public domain especially by the media and health care workers. This effort should also be targeted at religious organizations, clerics and traditional institutions this is because most of these misconceptions have deep rooted religious and cultural sentiments. This can also be achieved by ensuring synergy between government, non governmental organizations,advocacy groups,traditional and religious rulers. Resume Objectif: Traditionnellement, la majorité des services et des campagnes de planification familiale sont axés sur les femmes, sans considération pour leurs partenaires masculins. Dans notre société, il y a des préjugés, des mythes et des idées fausses à propos de la vasectomie, ce qui a entraîné une réduction significative de la volonté des hommes à rechercher la vasectomie comme moyen de planification familiale. Cette étude vise à identifier le niveau de sensibilisation et d'acceptation de la stérilisation masculine chez les hommes à Ogbomoso, au sud-ouest du Nigeria. Keywords Méthodes:Cette étude était une enquête transversale réalisée chez des hommes à Ogbomoso, la participation était volontaire et trois cent hommes avaient rempli les questionnaires et pouvaient être analysés.Résultat: Cette étude a révélé un haut niveau de sensibilisation aux méthodes de planification familiale chez les hommes à Ogbomoso. Cependant, moins de la moitié de ces hommes étaient d'accord pour dire que les hommes devraient être impliqués dans la planification familiale, même si un plus grand nombre de répondants étaient conscients de la vasectomie comme moyen de contraception. Les raisons communes pour ne pas accepter la vasectomie variaient de la préférence pour d'autres méthodes de contraception, les tabous culturels, les sentiments religie...
