Generally, most of the follicles undergo atresia during their development in mammals, and only a few grow to maturation and ovulation. For many years, the mechanisms of follicular atresia have been one of the foci of study. Recently, with the development in studies on cell apoptosis, it has been proved that follicular atresia is a process of cell apoptosis. However, the endocrinological and molecular evens underlying follicular development and atresia and granulosa cell apoptosis in the goat has not been studied.
