Medications: Tamoxifen

Tamoxifen is a medication that is primarily used to prevent breast cancer.

However, it can induce ovulation induction by a mechanism similar to clomiphene citrate, but is more estrogenic in the cervix and uterus than clomiphene citrate.

The benefit of Tamoxifen is its ability to induce ovulation while minimizing the antiestrogenic action of the cervix and uterus.

Typically Tamoxifen is given at a dose of 10 to 20 mg per day on either cycle days three to seven or five to nine. It is administered orally.
