LH commonly refers to Luteinizing Hormone in biology or medicine. It's a hormone produced by the pituitary gland and plays a vital role in regulating the reproductive system for both men and women. Here's a detailed breakdown:
Luteinizing hormone (LH) levels decrease significantly after the ovulation surge. Once the egg is released from the follicle, the ruptured follicle transforms into a structure called the corpus luteum. This structure primarily produces progesterone, which is crucial for preparing the uterus for pregnancy.
As progesterone levels rise, they exert a negative feedback effect on the pituitary gland, reducing the production of both LH and follicle-stimulating hormone (FSH). This decline in LH levels is necessary to maintain the corpus luteum and support the early stages of pregnancy.
