- EMBRYOLOGY LAB NOTES A. Syngamy: 1. Of the of sperm that are ejaculated into the vagina, only a few thousand make it all the way out into the 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 and the deeper Hundreds of sperm must release their acrosomal enzymes before theses barriers are breached, and sperm fuses with the oocyte's membrane. 3. As this sperm loses its and its nucleus is pulled into the oocyte cytoplasm, changes occur in the oocyte membrane, thus preventing other sperm from entering (and ensuring in humans). 4. The secondary oocyte is now able to complete meiosis II, forming and ovum and a second The sperm nucleus swells to form the male pronucleus chromosomes); the ovum nucleus also swells to become the chromosomes).
