Question

How sperm enters into ovary!?​

Answer 1

• As the fallopian tube pushes the egg towards the uterus, cilia push the sperm towards the egg. Progesterone and estrogen influence this process by increasing the number of cilia and how fast they move (1). The egg and surrounding cells produce a chemical that attracts sperm (1,7).

Answer 2

Answer:

To enter the egg, the sperm has to do two things:

Break through a group of cells known as the cumulus oophorus that surround the egg. The sperm dissolves these cells using an enzyme (1,7). Break through the outer membrane of the egg. The sperm essentially fuses to and digests this membrane using an enzyme (1,7).
