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
The mid-cycle surge of luteinizing hormone (LH) is a crucial event in the female menstrual cycle. It marks the point of ovulation, where a mature egg is released from the ovary.
Key Points About the LH Surge:
- Timing: It typically occurs around 12-14 days before the start of the next menstrual period.
- Trigger for Ovulation: The surge in LH triggers the final maturation of the egg and its release from the follicle.
- Hormonal Changes: The rising levels of estrogen during the follicular phase provide the necessary feedback to stimulate the LH surge.
