Most sperm
survive for
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.
2. The ovulated secondary oocyte is encapsulated by two walls, the

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

3. As this sperm loses its
