Sperm Morphophysiology in Different Sections of the Rooster Reproductive Tract
SUMMARY: It is important to know the morphological changes that occur in the spermatozoa of rooster during their passage through the reproductive tract, which help to understand what they acquire their fertilization capacity. The morphophysiological changes related to the capacitation and acrosomal...
