MATURATION OF SPERMATOZOA IN THE RABBIT EPIDIDYMIS : FERTILIZING ABILITY AND EMBRYONIC MORTALITY IN DOES INSEMINATED WITH EPIDIDYMAL SPERMATOZOA

Fertilizing ability of cryopreserved spermatozoa in the Persian sturgeon (Acipenser persicus) and stellate sturgeon (A. stellatus)

Motility of spermatozoa was studied on 12 and 7 specimens of Acipenser persicus and A. stellatus, respectively. The density measured to be 2.22±0.65x109ml-1 in A. persicus and 2.21±0.55x109ml-1 in A. stellatus. Semen samples were diluted with two extenders containing tris 118mM, sucrose 23.4mM, pH=8, egg yolk (20%), dimethyl sulfoxide (15%) and penicillin potassium (500IU/ml) and biociphus exte...

Relations between the fertilizing ability, motility and metabolism of epididymal spermatozoa.

This paper compares the principal modifications taking place in spermatozoa during epididymal transit in several species. The relations between changes in the epididymal medium and modifications in the metabolism, motility and/or fertility of spermatozoa are reviewed with particular reference to spermatozoon forward motility. The fertilizing ability of motile testicular and epididymal spermatoz...

The fertilizing life of spermatozoa in the rabbit oviduct.

Improving the fertilizing ability of sex sorted boar spermatozoa.

The sex sorting of spermatozoa by flow cytometry induces damage, since sperm cells are highly diluted, affecting their functionality and fertilizing ability. In this work it was investigated whether the concentration of sex sorted spermatozoa by the sedimentation method, rather than centrifugation, in combination with the presence of the seminal plasma protein PSP-I/PSP-II heterodimer may impro...
