How do fertility medications work?

Fertility medications work by addressing hormonal imbalances or stimulating ovulation. Common types include:

1. Clomiphene Citrate (Clomid): Stimulates the ovaries to produce more eggs by blocking estrogen receptors.
2. Gonadotropins: Hormonal injections that directly stimulate the ovaries to produce eggs.
3. Letrozole: An aromatase inhibitor that can help stimulate ovulation, often used in women with PCOS.
4. Metformin: Commonly used for women with insulin resistance or PCOS to help regulate ovulation.
