PURPOSE Assisted reproductive technology (ART), including in vitro fertilization and intracytoplasmic sperm injection, is routinely used to treat male factor infertility. Because of the success of ART, the optimal method to achieve pregnancy with male infertility is controversial. Two examples in which ART competes with traditional male infertility treatments are varicocelectomy and vasectomy r...

Introduction Vasectomy is the simplest, safest, and most effective form of definitive fertility control in men [1]. Vasectomy is used for 10% of contraception worldwide but only for 2% in Germany [2]. The aim of this study was to investigate the impact of vasectomy on the sexual satisfaction of sterilized men and their partners. Material and methods Vasectomized men and their partners were su...

introduction:  vasectomy is a simple and highly effective contraceptive method. comparing with tubectomy, vasectomy is much less likely to have serious complications, failure and costs. the knowledge and attitude play an important role in approving and using vasectomy. this study was designed and conducted in zahedan high schools in 2002, to investigate the knowledge and attitude of male and fe...

Between 1975 and 2003, a total of 4010 patients have undergone microscopic vasectomy reversal by 1 surgeon at 1 institution. Of these cases, 3904 had available records and 1735 were successfully contacted to obtain reliable long-term data. A total of 1556 (89.7%) were able to establish a pregnancy in their female partner, resulting in 2111 pregnancies. When there was no sperm in the vas fluid a...

The mammalian epididymis is a fundamental organ for sperm cell maturation; it allows mammals to acquire their fertilizing ability. We have previously shown that during obstruction in cases of vasectomy, gene expression profiles were modified in human and cynomolgus monkey epididymides. Paracrine factors thus appear to be key elements in local gene expression along the epididymis. Local renin-an...

BACKGROUND The effects of vasectomy on spermatogenesis and reproductive parameters are recognized to be specie-dependent with marked differences in levels of perturbations observed. OBJECTIVES To assess the impact of unilateral vasectomy on testosterone level and other testicular parameters in the male African giant rat (AGR) (Cricetomys gambianus). METHODS Sixteen adult male AGRs weighing ...

vasectomy is one of the extensively used methods of contraception in family planning programs. antisperm antibodies (asa) develop after vasectomy which can result in auto-immune male infertility. the precise sperm antigens involved in the autoimmune response are still poorly defined, therefore we determined the circulating asa and identified relevant sperm antigens based on localization of bind...

Macroscopic and microscopic study of the testis after vasectomy and ligation of vasefferentia of testis in adult male albino rats. a b c d Original Article Vasectomy Fertility Adult male albino rats Sexual potency The present study is done to reassess the effects of ligation of excurrent duct system of testis at different levels in adult male albino rats and to study the long term effects of va...

This study provides quantitative information on the early (up to 3 months) effects of vasectomy on apoptosis in the hamster testis. Groups of five adult male golden hamsters were either bilaterally vasectomized or sham-operated and sacrificed at intervals of 3, 6, and 12 weeks after surgery. In all three postvasectomy groups, testis weight and testicular and plasma testosterone (T) levels were ...
