Reproductive biology of pêga jackasses: Characteristics of sperm-rich fraction collected using the split-ejaculate method
(2016-01-01)
The aim of this study was to evaluate the physical and morphological characteristics of the sperm-rich fraction of jackass semen. To this end, 130 ejaculates from five Pêga jackasses were collected using an open model ...
Sperm sexing with density gradient centrifugation in dogs
(Elsevier B.V., 2018-12-01)
Sexed sperm in dogs is of interest because of being polytocous, and as a result, the greatest number of offspring of the same sex can improve the market, although few studies assessing sperm sexing have been performed in ...
Sexual maturation of the Mongolian gerbil (Meriones unguiculatus): a histological, hormonal and spermatic evaluation
(2014)
This study determined the phases of sexual development of the male Mongolian gerbil (Meriones unguiculatus) based on an integrative analysis of testicular morphology, hormonal data and sperm parameters. Male gerbils were ...
Cryopreservation and fertility of ejaculated and epididymal stallion sperm
(Elsevier B.V., 2011-09-01)
The cryopreservation of epididymal sperm is important to preserve genetic material from valuable deceased males. This study evaluated the viability of sperm samples from eight stallions under three conditions: (1) collected ...
