This was a cohort study of in vitro fertilization(IVF)subjects at the University of Utah,Salt Lake City(UT,USA)utilizing partner sperm.Cycles where both the hamster egg penetration test(HEPT)and semen analysis were pe...
Mammalian fertilization is a complex process that involves different steps of interaction between the male and female gametes. In spite of its relevance, the molecular mechanisms underlying this process still remain t...
One of the most common lesions present in the spermatozoa of human infertility patients is an idiopathic failure of sperm-egg recognition. Although this unique cellular interaction can now be readily by-passed by assi...
Fertilisation in mammals involves many synchronized steps including spermegg adhesion. Prior to sperm-oolemma fusion, spermatozoa need to undergo the acrosome reaction (AR) or exocytosis. The universal belief, for ...
An average human ejaculate contains over 100 million sperm, but only a few succeed in accomplishing the journey to an egg by migration through the female reproductive tract. Among these few sperm, only one participate...

To study whether the antibody against the testis form of the nuclear autoantigenic sperm protein(tNASP)could result in reproductive failure,we successfully cloned and expressed a 339-bp cDNA fragment of mouse tNASP(mt...
Aim: To study the influence of Ureaplasma urealyticum (Uu) infection on the sperm egg binding associated molecule, sulfoga-lactosylglycerolipid (SGG). Methods: Epididymal sperm was collected from adult mice. The sperm...
