What happens during fertilization in humans
after many sperms reach close to the ovum?
Only two sperms nearest the ovum
penetrate zona pellucida
Secretions of acrosome helps one sperm
enter cytoplasm of ovum through zona
pellucida
All sperms except the one nearest to the
ovum lose their tails
Cells of corona radiate trap all the sperms
except one.
