What is Follicle Stimulating Hormone (FSH)?

Follicle Stimulating Hormone is measured as part of a female hormones panel. Your FSH is within the typical reproductive-age range. FSH varies across the menstrual cycle, so your doctor interprets it alongside the cycle day.

What does a high Follicle Stimulating Hormone mean?

Your FSH is elevated. In women, a high FSH can indicate reduced ovarian reserve or menopause; it's interpreted with LH, estradiol, and your age.

What does a low Follicle Stimulating Hormone mean?

Your FSH is low. In the context of fertility, low FSH can relate to signaling from the brain/pituitary. Interpretation depends heavily on your cycle phase and clinical picture.

Understand your whole report, not just one number

A single value rarely tells the full story — Follicle Stimulating Hormone is best read alongside the rest of your panel. Paste your values or upload your report and get a plain-English explanation of every marker, with the important results flagged.
