Antioxidant Supplementation And Purification Of Semen For Improved Artificial Insemination In Livestock Species, Peter Petruska, Marcela Capcarova, Peter Sutovsky

Improving sire reproductive performance in artificial insemination (AI) programs and maximizing the use of sires with valuable genomes are high on the list of priorities for livestock breeders in the United States and worldwide. While fixed-time AI and accurate estrous detection have already ameliorated the reproductive management of cows and sows, substantial gains remain to be made in the selection and utilization of male animals for field AI. In addition to better, more objective evaluation of breeding soundness and semen quality, numbers of spermatozoa per AI dose could be reduced and numbers of AI doses per collection could be increased …

Bull fertility, defined as the ability of the spermatozoon to fertilize and activate the ovum and then support embryonic and even fetal development, is a crucial factor influencing animal reproduction and production efficiency. Despite significant influences of fertility on herd genetic improvement and efficient cattle production, the mechanisms regulating this phenotype and reliable biomarkers associated with bull fertility are poorly defined. Specifically, there is a broad lack of knowledge in bull fertility. In this paper, bull fertility is reviewed within the context of animal systems physiology, and system biology markers associated with bull fertility are provided. This mini-review is intended …

Cholesterol Efflux From Sperm: Approaches And Applications, Zahid Naseer, Ejaz Ahmad, Meli̇h Aksoy
Turkish Journal of Veterinary & Animal Sciences
Following ejaculation, sperm appear morphologically mature, but functionally they are inactive. To attain functional capability or capacitation in vivo, sperm must reside in the female reproductive tract for a certain period of time before fertilization. In the female reproductive tract, cholesterol efflux from the sperm plasma membrane is considered vital for the initiation of capacitation. A number of in vitro studies have used biological and nonphysiological means to understand the phenomenon of cholesterol efflux and capacitation. In this review, we present a short overview of the role of cholesterol efflux in regulating sperm capacitation using various agents. This review provides …
