Can menstruation occur even if the ovaries do not ovulate?

Many adult women find that they sometimes do not ovulate during their ovulation period. If this phenomenon occurs frequently, it can easily lead to infertility. Some people may find it strange: "Will menstruation occur if the ovaries do not ovulate?" The answer is yes. Menstruation will occur even if there is no ovulation. Let me give you a detailed introduction to the reasons below!

Can menstruation occur even if the ovaries do not ovulate? Because under the influence of certain factors, the follicles will no longer mature after reaching a certain stage of development and will not ovulate. However, such follicles also produce estrogen, causing the endometrium to proliferate; later, the follicles atrophy, and the estrogen level in the blood suddenly drops. The endometrium loses the support of estrogen and collapses, causing bleeding. However, on the surface, it is often no different from normal menstruation with ovulation, but in this case it is easy to cause anovulation and infertility.

During puberty, girls' follicles begin to grow and develop, but the hypothalamus-pituitary-ovarian gonad axis has not yet established a normal relationship and the endocrine system is unstable, so most menstruation is without ovulation. In menopausal women, the ovarian function gradually declines, and they first experience anovulation, and then the follicles completely stop growing. Therefore, women in adolescence and menopause often have anovulatory menstruation and are also prone to anovulatory functional uterine bleeding.

Ovulation stops after pregnancy, and women who give birth or have miscarriage need to resume ovulation, so they are more likely to have anovulatory menstruation first. As for the use of estrogen or progesterone drugs, which cause endometrial hyperplasia or secretion, the bleeding that occurs after stopping the medication, although it is also cyclical, can only be called withdrawal bleeding, not true menstruation.

After reading the above text, I believe you are all very clear about the reasons for menstruation without ovulation. If you do not ovulate occasionally, it generally has little impact. But if this phenomenon occurs frequently during the childbearing age, you must pay attention to it. It is very necessary to find out the reasons for not ovulating in time.
