Letrozole and Estrogen Suppression

Letrozole stops making estrogens. Estrogens are made in many places like the ovaries and brain. Letrozole mechanism of action stops aromatase, lowering estrogen levels.

This makes the pituitary gland release more FSH. FSH helps follicles grow and ovulate.

Impact on Ovulation Induction

Letrozole lowers estrogen levels, helping ovulation. With less estrogen, the body thinks it needs more. This makes more follicles mature and release eggs.

This makes ovulation happen naturally. Letrozole is key in helping women with infertility.

Inhibition of aromatase enzyme Estrogen suppression
Reduction of estrogen levels Increased FSH production
Stimulation of ovarian follicles Ovulation induction

This difference affects how well each drug works for different people.

Side Effects

Both drugs have side effects, but they’re not the same. Letrozole can cause tiredness, dizziness, and headaches. Clomid might lead to hot flashes, mood changes, and a condition called OHSS.

It’s important to look at these side effects when choosing between Letrozole and Clomid.
