Letrozole is a fertility medicine that helps stimulate ovulation by temporarily lowering estrogen, which signals the brain to release more FSH and LH so the ovaries are more likely to mature and release an egg. It’s commonly used for people with irregular ovulation , especially PCOS , and it can sometimes help if Clomid hasn’t worked well.

Quick Scoop

  • Main job: Encourages the ovaries to make and release an egg.
  • How it works: Lowers estrogen briefly, which boosts FSH/LH signals from the brain.
  • Who it may help: People who don’t ovulate regularly, including many with PCOS.
  • Why doctors use it: It can improve ovulation and, in some cases, pregnancy chances.

In simple terms

Think of letrozole as a “push” to help your body start an ovulation cycle more reliably. By reducing estrogen for a short time, it nudges the hormonal system to get follicles growing, which can lead to egg release.
