What do your LH levels mean?
The short answer
Nobody we follow has said what your LH should be. It comes up on the shows, but never with a number.
Your lab prints 1.9–12.5 mIU/mL. That range exists to catch disease, not to describe your best.
Labs print different ranges by sex: about 1.9–12.5 mIU/mL for women and 1.7–8.6 for men.
What LH measures
A pituitary hormone that triggers ovulation and tells the testes to make testosterone.
Read with FSH and the sex hormones, it separates a problem in the ovaries or testes from one in the pituitary.
Checked against MedlinePlus — Luteinizing Hormone (LH) Levels Test.
