What it means

FSH stands for Follicle Stimulating Hormone. It is a hormone that helps the ovaries grow and prepare eggs each cycle. The level of FSH in the body can give a signal about how hard the body is working to stimulate the ovaries.

When it’s used

It’s usually tested early in the menstrual cycle as part of fertility checks. In IVF, it helps give more context alongside AMH to understand how the ovaries may respond.

Why people get confused

Some people try to read FSH as a “good or bad” number on its own. But FSH doesn’t work alone. A higher level can mean the body is trying harder to stimulate the ovaries, but it needs to be understood together with other results like AMH.

Think of it this way

If AMH is about how many eggs might be available, FSH is more about how much effort the body needs to use to get things going.

What to expect

FSH is measured through a blood test, and the result is usually one number. This number is interpreted together with other tests, so it’s part of a bigger picture rather than a final answer on its own.
