In vitro fertilization of intact sheep and cattle oocytes with goat spermatozoa
1992
Slavik, T. | Fulka, J.
In an earlier study we reported on the fertilization of in vitro-matured bovine oocytes by ram spermatozoa. The present results extend those observations and demonstrate the penetration of bovine and ovine oocytes matured in culture by goat spermatozoa. Freshly ejaculated and in vitro capacitated goat spermatozoa penetrated 37.1% of bovine and 48.1% of ovine intact oocytes. Monospermic fertilization was detected in about 90% of the oocytes of both species, and the development of pronuclei followed a developmental pattern similar to that of homologous fertilization.
