Fertility In Rabbits Inseminated With Diluted or Washed Spermatozoa

Spermatozoa Molecules in Relation to Bulls Fertility

Bull fertility may be defined as the process by which spermatozoa fertilize and activate the ovum and then support embryonic development. Bull fertility is a complex trait having relatively low heritability and plays a vital role for efficient production and reproduction of bovine. Various mechanisms involved in regulating bull fertility associated phenotype and reliable biomarkers are poorly d...

Micro-cell chamber and washed human spermatozoa.

With the development of the Makler counting chamber, the reproducibility and accuracy of computer-assisted semen analysis and of manual determination of sperm concentration and sperm motility were significantly enhanced beyond what is possible with other methods, such as the hemocytometer, the Horwell chamber, the Petroff-Hausser chamber, and Chartpak slides. The use of Micro-Cell, a disposable...

Oocyte penetration by fresh or stored diluted boar spermatozoa before and after in vitro capacitation treatments.

This study examined whether washing and preincubation of boar spermatozoa was necessary to achieve high in vitro penetration rates of pig oocytes. In experiment 1, diluted, sperm-rich fractions, stored for 24 h at 16 degrees C (stored diluted sperm) were used. After centrifugation once at 50 g for 3 min, the supernatant was concentrated at 1200 g for 3 min. The pellets were washed (1200 g for 3...

The Detection of Spermatozoa on Washed Forensic Exhibits

Viability and fertility of rabbit spermatozoa diluted in Tris-buffer extenders and stored at 15 degrees C.

Artificial insemination (AI) in rabbits is not extensive in the breeding programs of the rabbit meat industry. A limiting factor is related to the semen preservation. In order to improve the use of AI, two experiments have been conducted to evaluate sperm viability and fertility of rabbit semen chilled and stored at 15 degrees C after dilution in Tris-based extenders. In Experiment 1, pooled se...
