hours inside the female, and the ovulated oocyte is viable for
hours. For fertilization to occur, coitus must occur no more than
days prior to ovulation and no later than
hours after.

must release their acrosomal enzymes before theses barriers are breached, and

3. As this sperm loses its

changes occur in the oocyte membrane, thus preventing other sperm from entering (and
