Does Luteinizing Hormone Cause Ovulation
Q: Does luteinizing hormone trigger ovulation?
A: Luteinizing hormone plays a key role in the process of ovulation in women. When the luteinizing hormone in a woman's body reaches a peak, this is an important sign that ovulation is about to occur.
During a normal menstrual cycle, the hypothalamus secretes gonadotropin-releasing hormone, which acts on the pituitary gland and causes the pituitary gland to secrete follicle-stimulating hormone and luteinizing hormone. Follicle-stimulating hormone can promote the development and maturation of follicles, and as follicles develop, the amount of estrogen secreted also increases. When estrogen secretion reaches a certain level and is maintained for a certain period of time, it will have a positive feedback effect on the hypothalamus and pituitary gland, causing the pituitary gland to secrete a large amount of luteinizing hormone, which is the peak of luteinizing hormone.
This peak of luteinizing hormone is of great significance to the occurrence of ovulation. It can enhance the lysase activity of the mature follicle wall, make the follicle wall dissolve and release; at the same time, it can promote the follicle to secrete prostaglandin, which can cause the muscle-like cells of the follicle wall to contract, and help the follicle rupture and ovulation. If the secretion of luteinizing hormone is abnormal or the peak of sufficient intensity cannot be formed, it is very likely to cause ovulation disorders and affect the reproductive function of women. Therefore, luteinizing hormone can indeed trigger ovulation and is an indispensable factor in the ovulation process
