Question

What is the fate of released egg in female, if fertilization doesn't occur?

Answer 1

It will form corpus leutem and the uterus wall will get thinner

Answer 2

A male releases sperm when he ejaculates and a female releases anegg each month, during ovulation. It only takes one sperm to fertilize anegg. So, if an egg and sperm meet (anegg is fertilized), it travels down the fallopian tube and implants in the lining of the uterus. If this happens, afemale becomes pregnant.
