Luteinizing Hormone (LH) is a key reproductive hormone that plays a critical role in the menstrual cycle. In people with ovaries, a surge in LH triggers ovulation — the release of an egg from the ovary — making it a vital marker for tracking fertility and understanding hormonal balance.
How Does LH Indicate Ovulation or Fertility?
An LH surge typically occurs 24 to 36 hours before ovulation, making it one of the most reliable signs that the body is preparing to release an egg. LH levels can fluctuate throughout the cycle, so tracking it helps identify your fertile window, whether you're trying to conceive or just monitoring your cycle.
