What medication is best for increasing fertility in woman?

Clomiphene or Femara (letrozole): The choice of medication depends on the type of patient, but the first line of treatment is clomiphene, an oral medication used to induce follicular growth and ovulation. It is inexpensive and relatively safe, but can lead to multiple pregnancies (8%) and supresses the uterine lining. Femara (letrozole) is an oral alternative to Clomiphene that does not affect the endometrium. Both are equally effective.

Fertility medication: Agents which can increase fertility are those which stimulate ovulation. Follistim, clomiphene citrate, and used in "in vitro fertilization" (IVF) is Pergonal to stimulate multiple eggs for harvesting for embryo production. If pregnancy is desired, consult a reproductive endocrinologist for treatment options.
