Deskripsi
Rate of ovulation (i.e. fecundity) is largely influenced by both genetic and environmental factors. The ovarian growth factorsincluding members of bone morphogenetic proteins (BMPs) play a central role in determining ovulation quota and litter size.Naturally occurring mutation in sheep and knock-out and knock–down studies in murine indicated the importance of bonemorphogenetic protein 15 (BMP15), growth differentiation factor 9 (GDF9) and bone morphogenetic protein receptor 1B(BMPR1B) genes in mammals. These factors have major regulatory roles during the gonadotrophin-independent and -dependent stages of follicle development. Understanding of BMPs in reproduction assists in the treatment of infertility/sterility in animals.
