A ram epididymal secretory protein shares common antigenic determinants with rat epididymal proteins and human seminal plasma proteins.
Mammalian spermatozoa leave the testis as immature cells unable to fertilize until they have traversed the epididymis. Sperm maturation is an orchestrated series of sequential events occurring at different levels of the epididymis : sperm-zona pellucida binding ability in the proximal epididymis, progressive motility and the ability to penetrate and fertilize the oocyte in the middle epididymis...
متن کاملSpecific basic proteins from mammalian testes. Isolation and properties of small basic proteins from rat testes and epididymal spermatozoa.
A unique acid-soluble basic protein was detected in the testes of sexually mature rats and a number of other mammalian species. This protein was not found in comparable acid extracts prepared from many other rat organs or from the testes of juvenile rats. It makes its appearance only after spermatids are evident in normally developing testes and is absent from the gonads of male rats rendered a...
متن کاملP-18: Effects of Ethanol Consumption on Chromatin Condensation and DNA Integrity of Epididymal Spermatozoa In Rat
Background: Alcohol abuse is considered as one of the problems associated with poor semen production and sperm quality. Both acute and chronic alcohol consumption may affect spermatozoal chromatin disorders through apoptosis. Therefore, for the first time, this experimental study was performed to evaluate the effect of ethanol consumption on sperm parameters and chromatin integrity of spermatoz...
متن کاملProtective effects of celery (Apium Graveolens) on testis and cauda epididymal spermatozoa in rat
Dear Editor Infertility is one of the health problems that will have a negative impact on the individual, social and economic and is seen in 10-15% of couples (1). About 40 % of the issues involved with infertility are due to the man. Male sperm cells count nowadays has decreased dramatically in comparison with those who lived 50 years ago (2). Causes of infertility in men are included: oligozo...
متن کاملCollection and freezing of equine epididymal spermatozoa
The first report of a foal born after artificial insemination (AI) with frozen/thawed semen, more than fifty years ago, was the result of insemination with epididymal spermatozoa (Barker en Gandier, 1957). Ever since, reports have confirmed pregnancies and/ or births after AI with epididymal semen, which proves the fertilizing capacity of epididymal semen (Morris, 2002; Monteiro et al., 2011). ...
