{{Main|Ovulation induction}}
The main [[ovulation induction]] medications include:
*[[Antiestrogen]], causing an inhibition of the [[negative feedback]] of estrogen on the [[pituitary gland]], resulting in an increase in secretion of [[follicle-stimulating hormone]]. Medications in use for this effect are mainly [[clomifene citrate]] and [[tamoxifen]] (both being [[selective estrogen-receptor modulator]]s), as well as [[letrozole]] (an [[aromatase inhibitor]]).<ref name=":6" />
*[[Follicle-stimulating hormone]] (FSH), directly stimulating the ovaries. In women with anovulation, it may be an alternative after 7–12 attempted cycles of pituitary feedback regimens (as evidenced by clomifene citrate), since the latter ones are less expensive and more easy to control.<ref name="WeissBraam2014">{{cite journal|last1=Weiss|first1=N.
