Menstruation is an important physiological phenomenon of women in childbearing period. One of the important organs to maintain women's normal menstruation is ovary, which can produce eggs and secrete sex hormones. There are about 2 million follicles at birth. Most follicles in childhood gradually degenerate, and there are only about 300000 follicles left at the age of 10. Why say follicles, because they are the basis of luteal formation Because the ovary changes periodically, women's menstruation also has a very regular periodicity, just like the tide of Qiantang River. What's the reason for the long luteal phase.

What is the reason of long luteal phase

Second: if you have regular menstruation, such as a cycle of 28 days on average, the follicle will grow to the largest on the 14th day of your menstruation, about 2 cm, and then begin to ovulate under the action of hormone, that is, the egg will come out from the follicle.

Third: after arranging the eggs, there is a layer of follicle wall and some cells and tissues outside, and a corpus luteum will gradually form. Then, the time when your next menstruation comes is the luteal phase. Sometimes, when you go to B-ultrasound, you may see a cyst or something, which may be the corpus luteum, so don't worry too much.

If you are in the same room before and after ovulation, and there is no contraception, if the egg encounters sperm, the corpus luteum will become pregnant corpus luteum, which mainly secretes hormones to maintain the development of the fertilized egg, It usually doesn't disappear until 3 months of pregnancy.
