Strangely, there is the presence of a hormone (the lining of the uterus causes the uterine lining, which are developed paid in the blood vessels), but the absence of the hormone progesterone, which causes the event.
Progesterone is the "scar" (called the corpus luteum - which means the corpus luteum) in the ovary where the egg exploded. The uterus, when oust a foreign body in the contracts of foreigners. Effect of progesterone is that it contracts the uterus is stopped when an object in the uterus.
During the menstrual cycle (no menstrual period), the flow of the uterine lining, the endometrium, the growth of blood vessels and blood through the blood vessels. The endometrium and associated blood vessels and the is, which ruled during menstruation. The endometrium serves as a foreign body in the uterus. If a fertilized egg implant, then the endometrium can only be paid as if they were the egg will be flushed, too. Progesterone stops the tightening or spasms in the uterus to expel the endometrium.
Then when the eggs are implanted, is a hormone hCG () human chorionic gonadotropin. HCG causes the corpus luteum cells remain "healthy" and its functioning. Thus, from the corpus luteum produces progesterone continues to be produced and the endometrium is not excluded, and the woman is pregnant.
However, if the egg is not fertilized, the corpus luteum stops degenerates (no HCG) and progesterone. Without ProProgesterone, rejects the uterus with blood vessels in the endometrium and is associated with increased blood vessels are.
