What is the role of hyaluronidase in fertilization?
What is the role of hyaluronidase in fertilization?
- Dissolving the zona pellucida of the ovum
- Binding specifically with receptor proteins in the zona pellucida
- Opening pathways between granulosa cells for sperm to reach the ovum (correct)
- Stimulating the Sertoli cells for germ cell activity
What happens within minutes after the sperm reaches the zona pellucida of the ovum?
What happens within minutes after the sperm reaches the zona pellucida of the ovum?
- The sperm head fuses with the oocyte cell membrane
- The genetic material of the sperm and oocyte combine to form a new cell genome
- The entire acrosome dissolves and releases all acrosomal enzymes (correct)
- The Sertoli cells are stimulated for germ cell activity
