TRA98 is a rat monoclonal antibody (mAb) which recognizes specific antigen in the nuclei of germ cells. mAb has been used to understand mechanism cell development and differentiation many studies. In mice, recognized by or GCNA1 reported be GCNA gene product, but despite demonstration immunoreactivity this human testis sperm 1997, humans remains unknown, as date. To identify TRA98, comprehensiv...

Triorchidism is the commonest variety of polyorchidism, an entity with more than two testis is an extremely rare congenital anomaly of the testis. Although excision of the abnormal testis is a safer alternative proposed, recent literature suggests more conservative approach in normal testes with watchful regular follow up to screen for malignancy. This case presented as a left inguinal swelling...

Unilateral orchidectomy (UO) is required when further breeding potential is important. It is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. In this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. Results of the study showed that each of the surgica...

Background: Reproductive dysfunction and endocrine disorders are common among men with complex partial seizures of temporal lobe origin. More than 90% of men with epilepsy have abnormal semen analysis, including decreased sperm count, abnormal morphology, and impaired motility. The aim of this study was the assay of chronic treatment with melatonin during the latent phase and chronic phase of e...

abstract: background: the availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (noa). cdy1 histone acetyltransferase is a histone modifier which concentrates in the nucleus of round spermatids, where histone hyperacetylation occurs and causes the replacement of...

PURPOSE betaB2-crystallin is one of the most abundant proteins of the adult ocular lens of mammals although it is expressed at lower levels in several extralenticular locations. While mutations in betaB2-crystallin are known to result in lens opacities, alterations in tissues besides the lens have not been previously investigated in these mutants. Since we found mice harboring the Crybb2Phil mu...

background: the predominant phytoestrogen in soy and derived products is the isoflavone genistein. genistein has antioxidant properties. morphine is a main psychoactive chemical in opium that can increase the generation of free radicals and therefore it could adversely affects the spermatogenesis. objective: the main goal was to investigate whether the genistein could protect morphine adverse e...

ESP1/SPESP1 is a testis-specific, postmeiotic gene expressed in round spermatids that encodes equatorial segment protein 1, an intra-acrosomal protein found in the acrosomal matrix and on the luminal surface of the inner and outer acrosomal membranes within the equatorial segment domain of mature spermatozoa. A comparison of testicular protein extracts with caput, corpus, and caudal epididymal ...

This study investigated the protective effects of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced testicular toxicity in male rats. DADS was gavaged to rats once daily for 3 days at 100 mg/kg/day. One hour after the final DADS treatment, the rats were given a single intraperitoneal dose of 150 mg/kg CP. All rats were killed and necropsied on day 56 after CP treatment. Parameters ...
