On the Suitability of Luteinizing Hormone
Luteinizing Hormone (LH) is the key to the order of human physiology. The suitability of its level varies depending on the individual and the physiological stage.

If you are a woman of childbearing age, the level of LH changes dynamically during the menstrual cycle. During the intermenstrual period, its value rises sharply, such as the peak, which is an important sign of ovulation. At this time, the level of LH can reach several times that of normal prime, and it is prepared for the release of eggs. Before ovulation, LH may reach dozens of international units per liter to initiate the process of egg rupture and egg escape. In the follicular stage and the luteal stage, the level is relatively mild, about 2-15 IU per liter in the follicular stage and 1-10 IU per liter in the luteal stage, maintaining the stability of ovarian endocrine and regulating the secretion of estrogen and progesterone.

As for after menopause, women's ovarian function gradually decreases, and LH levels tend to increase. Because the feedback of the ovaries to gonadotropins is weakened, the compensatory secretion of the pituitary gland increases, and the value may reach tens or even hundreds of IU per liter. This is one of the symptoms of hormone imbalance in the body after menopause.

LH in men is responsible for stimulating testicular stromal cells to promote testosterone secretion. When normal, its level is about 1.7-8.6 international units per liter, which maintains the normal function of male reproduction and is related to the development of gonads and sperm production.

The guide for observing LH level is actually the basis for physicians to diagnose diseases and observe physiology. At the clinical stage, combined with the symptoms and signs of patients, the LH level can be studied, which can prevent ovulation and gonadal diseases and many other diseases. Therefore, it is clear that the appropriate level of LH is of far-reaching significance for the protection of human health.
