prosaposin（SGP-1） rooster sperm sperm-egg chickens
2008/12/26
A protein isolated from the supernatant of cryopreserved rooster sperm was found to increase the capability of cryopreserved rooster sperm to bind in vitro to the perivitelline membrane of a chicken e...
Objectively measured sperm motility and sperm head morphometry in boars（Sus scrofa）：relation to fertility and seminal plasma growth factors
sperm motility sperm head morphometry fertility seminal plasma growth factors
2008/12/26
This study was conducted to investigate the relationships between results of computer-assisted semen analysis (spermatozoal motility and sperm head morphometry) and fertility of boars. In addition, ...
Sperm calcium levels and chlortetracycline fluorescence patterns are related to the in vivo fertility of cryopreserved bovine semen
Sperm calcium levels chlortetracycline vivo fertility cryopreserved bovine semen
2008/12/25
Cryopreserved bovine semen is less fertile than fresh semen for reasons that have not been fully elucidated. Cryopreservation is known to disrupt the sperm plasma membrane and it induces premature c...
Correlation between clusterin-positive spermatozoa determined by flow cytometry in bull semen and fertility
Correlation clusterin-positive spermatozoa cytometry bull semen fertility
