The empty follicle now called the corpus luteum stays in the ovary and produces Progesterone. Since the built-up tissue and all its glands and blood vessels are needed for the embryo, they naturally just stay put if fertilization occurs. This effect was first described in 1971, and possibly explained by the action of in 1998.

As a woman's total egg supply is formed in fetal life, to be ovulated decades later, it has been suggested that this long lifetime may make the of eggs more vulnerable to division problems, breakage, and mutation than the chromatin of sperm, which are produced continuously during a man's reproductive life. D The mesometrium supports the uterine tubes along their entire length. It takes 13 days for the egg cell to reach maturity.
