A case of clomiphene-induced follicular growth in pregnancy is presented in
a 34-year-old woman with ectopic pregnancy treated at a university teachin
g hospital. Following administration of clomiphene citrate in pregnancy, fo
llicular growth to 18 mm mean diameter was noted. It is concluded that clom
iphene citrate can induce follicular growth and maturation in pregnancy, po
ssibly by reversing pregnancy-induced pituitary suppression.
