Previously spermatozoa in the semen of vasectomized men were reported in 62 of 63 specimens from 24 men 2 to 31 years postvasectomy (Freund and Couture, 1982). A morphologic basis and term, "microreca...
An indirect enzyme-linked immunosorbent assay (ELISA) was employed to monitor antisperm autoantibodies in 16 Lewis rats for up to 36 weeks following vasectomy. This assay was capable of discriminati...
The occurrence of spermatic granulomas of the vas deferens was studied in Lewis rats at intervals up to 7 months after vasectomy or vasectomy followed 3 months later by vasovasostomy. The incidence ...
The effects of vasectomy were examined by comparing various parameters from sham operated and vasectomized rats that had undergone surgery at 90 days of age and were killed at 190 or 390 days of age...
Ophthalmoscopic examination of the retinal vasculature of 159 men over age 30 showed a significant increase in mild vascular changes in vasectomized as compared to nonvasectomized men. Although th...
Intraluminal fluids from the hamster seminiferous tubules and cauda, corpus, and caput epididymidis were obtained in vivo using micropuncture techniques. The effect of vasectomy on the osmolarity ...
Serum chemistry parameters as well as levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and spermimmobilizing and sperm-agglutinating antibodies were measured pri...
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 bilaterall...
Intraluminal fluid movement rate was measured in four regions of the rat epididymis. The fastest flow occurred in the proximal caput epididymis (18.5 +/- 3.7 mm/hour) and the slowest in the distal...
Persistent infertility after apparently successful vasectomy reversal is common. One possible etiology is epididymal epithelial dysfunction resulting in improper sperm maturation after vasectomy ...
Vasectomy is one of the oldest and most commonly performed surgical procedures worldwide. Yet, as this thread on Androlog shows, there is no general agreement on the best approach to ensure contracept...
Clinical reproductive practice is often multivariate: multiple conditions in the male and/or female may coexist to confound diagnoses and therapeutic strategies. Given that treatment of an underlyin...
Histone-to-protamine exchange in haploid spermatids is known to play a central role for male fertility. The present study investigates, for the first time, the effects of vasectomy on the expression...
Coagulation factor (F) IX is a zymogen of the plasma serine proteases, one that plays an essential role in the regulation of normal blood coagulation. Congenital defects of FIX synthesis or functi...
The aim of the study was to determine whether the pregnancy rate with the same female partner or younger partners was higher compared with different or older partners after undergoing repeated vasec...
