What is the relationship between menstruation and ovulation in women?

Menstruation is a normal physiological phenomenon for female friends. We know that female friends' bodies are prone to various abnormal conditions during menstruation. Because female friends' immune function and digestive ability will decrease during menstruation, we recommend that female friends take good care of their bodies during menstruation. In addition, they should learn more about menstruation. Below we introduce the relationship between women's menstruation and ovulation.

The relationship between menstruation and ovulation: no ovulation, no menstruation

Menstruation and ovulation are closely related. Simply put, ovulation determines menstruation. Without ovulation, there will be no menstruation; to be more precise, without ovulation, there will be no ovulatory menstruation and no fertility. Therefore, to determine whether menstruation is normal, we should first determine whether ovulation has occurred. Menstruation with ovulation is normal.

Under normal circumstances, the menstrual cycle is controlled by the cerebral cortex and regulated by the interaction between the hypothalamus, pituitary gland and ovaries, and is also affected by other endocrine hormones such as thyroid hormone. Therefore, generally women secrete estrogen before ovulation, and progesterone and estrogen after ovulation.

It is under the action of these two hormones that the female endometrium undergoes changes between the proliferative phase and the secretory phase. Once the hormone level drops, the endometrium loses hormonal support and becomes necrotic and shed, and menstruation occurs. This is normal ovulatory menstruation. In anovulatory menstruation, the ovaries only secrete estrogen and not progesterone, so the endometrium only undergoes proliferative changes. When estrogen drops to a certain level, the endometrium is shed and women begin menstruating.

In the above article, we introduced the importance of menstruation to female friends. We suggest that female friends must pay attention to the changes in menstruation in their daily lives, and pay attention to any abnormal situation. The above article introduces in detail the relationship between women's menstruation and ovulation.
