Induction of ovulation in infertile women with pituitary tumors.

Four infertile women with pituitary adenoma were treated with human pituitary gonadotropins (HPG) in order to enable them to become pregnant. During pregnancy they contracted headache, bitemporal visual field defects, or impaired visual acuity. One woman was operated upon in the second trimester; the other three, as the symptoms were relatively moderate and no risk of permanent damage to the optic tract existed, went to term. After operation or delivery the symptoms disappeared.
