- Human fertilization is internal and viviparous.
- Only one ovum is released in human females during the menstrual cycle.
- Human males produce 300-400 million sperms per ejaculation.
- Capacitation is a process that provides sperms the ability to fertilize an ovum.
- Fertilization involves the approximation of sperm and ovum.
- The acrosome reaction occurs when the acrosome covering degenerates and enzymes are released.
- The egg reaction involves the development of a fertilization cone and the extrusion of cortical granules.
- The activation of the ovum involves meiosis II and the extrusion of a secondary polar body.
- The fusion of sperm and egg nuclei forms a synkaryon and the fertilized egg is called a zygote.
