Compromised sperm protein phosphorylation after capacitation, swim-up, and zona pellucida exposure in teratospermic domestic cats
Cat sperm teratospermia tyrosine phosphorylation zona pellucida
2009/2/16
Tyrosine phosphorylated proteins recently have been found in mouse and human spermatozoa. Our objectives were to (1) determine if domestic cat spermatozoa also express tyrosine phosphorylated pro...
Zona pellucida piercing enhances zona penetration by spermatozoa from normospermic and teratospermic domestic cats
Felid micromanipulation sperm teratospermia
2009/2/12
Poor quality ejaculates appear associated with reduced zona penetration and poor fertilization in vitro in some felid species or populations. Even morphologically normal sperm from these teratospe...
Teratospermia in domestic cats compromises penetration of zona-free hamster ova and cat zonae pellucidae
Teratospermia domestic cats compromises penetration zona-free hamster ova
2009/2/7
The ability of spermatozoa to bind and penetrate zona-free hamster ova and the zonae pellucidae of domestic cat oocytes in vitro was compared between normospermic (greater than 60% structurally norm...
Teratospermic and normospermic domestic cats：ejaculate traits, pituitary-gonadal hormones, and improvement of spermatozoal motility and morphology after swim-up processing
domestic cat sperm morphology teratospermia
2009/2/6
Electroejaculate traits, testicular volume, and circulating FSH, LH, and testosterone concentrations were compared between two populations of domestic cats consistently producing either a high (grea...
Recipient Preparation and Mixed Germ Cell Isolation for Spermatogonial Stem Cell Transplantation in Domestic Cats
Testis male radiation feline conservation
2008/12/23
The loss of genetic diversity poses a serious threat to the conservation of endangered species, including wild felids. We are attempting to develop spermatogonial stem cell transplantation in the cat ...
