LH

What is LH (Lutenizing Hormone)?

Luteinizing Hormone, or LH, is a hormone created in the pituitary gland, which oversees hormone production. In women, LH helps control the menstrual cycle and ovulation. In men, it tells the testes to make testosterone, which is a hormone important for things like muscle strength and facial hair. You can learn more about your testosterone levels here.

Why is it measured?

LH is helpful for a variety of bodily functions, such as:

  1. Ovulation analysis and tests
  2. Understanding issues with puberty
  3. Validating investigations of brain issues

How can I better understand my results?

In Males:

  • Low Levels: This may indicate a lack of testosterone production in men. 
  • High Levels: High levels may also indicate a lack of testosterone production, or production of nonfunctioning testes. 

In Females:

  • Low Levels: This could mean that your ovaries are not receiving the signal to produce eggs. This might be due to excessive stress or exercise. It could also be a sign of another underlying health condition. 
  • High Levels: Levels normally spike during the menstrual cycle. However, spiking at other times could be a sign of another health condition.
