Tumors vary in how they affect pregnancy depending upon the hormone secreted. Some hormone oversecretion syndromes must be controlled to allow pregnancy to proceed without undue maternal and fetal morbidity ( @entity699 and @entity1378 ) whereas treatment during pregnancy for other @entity5 is not necessary. Surveillance for @entity5 growth during pregnancy is necessary primarily for @entity2013 . A literature search was conducted to identify the effects of pregnancy on pre-existing @entity977 and the effects on the outcome of pregnancy due to hormone oversecretion by @entity977 . Results show that @entity4089 and @entity699 may interfere with fertility and usually need to be controlled to allow for conception. @entity699 , @entity2012 and @entity1378 secondary to hypersecretion of thyroid-stimulating hormone (TSH) may increase maternal morbidity (gestational @entity6 , @entity101 ) and fetal morbidity and mortality. Intervention is warranted to remove a @entity5 that secretes @entity4545 (ACTH) during pregnancy to reduce the risk of fetal loss and to control @entity1378 . In contrast, surgery or medical therapy for @entity652 that secrete @entity2124 ( @entity2124 ) and for clinically nonfunctioning @entity652 is not indicated during pregnancy. Pregnancy may cause an increase in the size of @entity5 that secrete prolactin (PRL), especially macroadenomas, so close surveillance is indicated and re-institution of @entity2847 therapy may be necessary to treat such an increase in @entity5 size. An increase in the size of other types of @entity5 during pregnancy is very rare.

XXXX and pregnancy.
