Sperm-associated retroviruses in the mouse epididymis.
Sperm adsorbed with retrovirus particles were recovered from the epididymis of apparently normal male mice. Epididymal semen from all four mouse strains examined was positive for retrovirus (10(5) to 10(8) particles per microgram of protein) indicating that epididymal fluids and sperm may be important vehicles for murine retrovirus spread. Immunoblot analyses revealed that the banding patterns ...
متن کاملSperm Proteome Maturation in the Mouse Epididymis
In mammals, transit through the epididymis, which involves the acquisition, loss and modification of proteins, is required to confer motility and fertilization competency to sperm. The overall dynamics of maturation is poorly understood, and a systems level understanding of the complex maturation process will provide valuable new information about changes occurring during epididymal transport. ...
متن کاملThe Protective Effect of Melatonin on Sperm Parameters, Epididymis and Seminal Vesicle Morphology in Adult Mouse Treated with Busulfan
Purpose: The aim of this study was to investigate the protective effect of melatonin on sperm parameters, epididymis and seminal vesicle morphology in adult mouse under chemotherapy. Materials and Methods: Male adult NMRI mice were divided into four groups. The control group received a single dose of DMSO, Group 2 received a single dose of busulfan 20mg/kg. Group 3 was administered melatonin 10...
متن کاملMouse epididymal sperm contain active P450 aromatase which decreases as sperm traverse the epididymis.
Recently we reported that mouse germ cells in the testis contain active P450 aromatase (P450arom), the enzyme that converts androgens to estrogens. This finding suggested that germ cells have the ability to produce estrogen. Further studies have shown that germ cells in the testis of several species contain P450arom. The goal of this study was to determine if epididymal sperm contain P450arom a...
متن کاملRole of the epididymis in sperm competition.
Although it is generally understood that the testes recruited kidney ducts for reproductive function during the evolution of vertebrates, little is understood of the biological significance of the adaptation. In the context of the evolution of the mammalian epididymis, this report provides evidence that a major role of the epididymis is to enhance a male's chance of achieving paternity in a com...
