Luteinizing Hormone Role in Menstrual Cycle
"On the role of luteinizing hormone in the menstrual cycle"
Menstruating people are often women. Its cycle is orderly and related to pregnancy. During this period, the role of luteinizing hormone (LH) is quite critical.
LH gradually gains its momentum at the beginning of the menstrual cycle. The hypothalamus secretes gonadotropin-releasing hormones, which stimulates the anterior pituitary gland to slowly release LH. At this time, LH and follicle-stimulating hormone (FSH) cooperate to promote the initiation of follicles. Follicles grow gradually in the ovaries, such as the bud of a tiller.
During the cycle, LH secretion jumps and reaches its peak. The power of this peak is like the chirping of the horns of the drum, causing the mature follicle to rupture and the egg to escape, which is ovulation. Without the promotion of this peak of LH, although the follicle is fertile, the egg cannot come out, and the road to conception is blocked.
After ovulation, the work of LH is not complete. It prompts the ruptured follicle to transform into the luteal body, which is the place where the progesterone and estrogen are secreted. Progesterone causes the endometrium to proliferate and thicken, creating a good environment for the implantation of the fertilized egg. If the egg is fertilized, the luteal body is nourished by hormones and continues to secrete hormones to maintain the beginning of pregnancy. If not fertilized, the luteal body gradually withers, hormone secretion decreases sharply, and the endometrium is
From this perspective, LH is interlinked and indispensable in the menstrual cycle, or to promote follicle development, or to induce ovulation changes, or to assist the formation of the luteal body. It has a great effect on women's pregnancy.
