Tienthai, P. 2003. Studies on the sperm reservoir of the pig oviduct. With special reference to intra-luminal fluid, hyaluronan contents and sperm capacitation. Doctor’s dissertation. ISSN 1401-6257, ISBN 91-576-6375-0. During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adja...

sperms are highly specialized cells for delivering dna from male to the ovum. incredibly, wide degree of diversity in sperm morphology in their basic structures i.e. head, middle piece and tail is found across species. differences in terms of overall size of the sperm, shape and number of sperm produced are also incredible. one of the key for this variations or diversity in sperm may be associa...

The goals of the present study were to develop a simple method for obtain highly purified pig sperm hyaluronidase (pHyase) and assess its activity, function, safety. In mammals, sperm-specific glycophosphatidylinositol (GPI)-anchored Hyase assists penetration through cumulus mass surrounding egg aids in dispersal oocyte complex. Recently, Purified bovine (bHyase) has been shown enhance therapeu...
