...Huan Jiang; Wei-Jie Zhu Introduction: Infertility in adulthood is a well-recognized consequence of cryptorchidism, even after successful orchidopexy. Autoimmune reactions against spermatozoa are associated with infertility and often found in cryptorchids. The purposes of this study were to evaluate...

...-stage sham operation and served as a control group (group B). Seven weeks after the second operation, serum urea and creatinine concentrations were evaluated. Caudal epididymal spermatozoa from rats with CRF but not from controls had been filtrated via Sperm Prep TM tubes to isolate the sperm fraction...

...K. Ohmori; T. Matsuda; Y. Horii; O. Yoshida Although many reports concerning the effects of shock waves on the human body have been published, their effects on the male reproductive system are not well known. This report examines the effects of shock waves on human spermatozoa and rat testes. Semen...

... was examined. The presence of auto-antibodies against spermatozoa could be proven by indirect immunofluorescence. After uni- and bilateral intra-abdominal displacement of the testicles, this phenomenon takes place after the 3rd month post-operatively, shows the maximum of titers after 6 months and decreases...

...A. Rost; U. Kneppenberg; U. Fiedler As a result of successful recanalization of the vas deferens, a low pregnancy rate has been observed. The formation of auto-antibodies is considered as cause. In vasectomized and epididymectomized rats, the presence of auto-antibodies against spermatozoa...

Results: The present study shows that the local biochemical milieu has some influence on the transport of spermatozoa through the male reproductive tract. The vas deferens showed a higher level of superoxide...
