Abstract

Erdheim and Stumme have demonstrated an increase in weight as much as twofold of the pituitary gland during pregnancy. There is very little increase in the anteroposterior and transverse axes of the gland due to the limited space available for expansion. The increase is thus primarily in height, which has been variously reported to increase from a mean 5.9 mm in the nulliparous woman to 7.5 mm at term, with a maximum size of 11.5 mm. The increase in circulating estrogen levels during pregnancy probably stimulates both hyperplasia and hypertrophy of lactotropic cells. Furthermore, there is a parallel between the increase in estrogen and prolactin levels during pregnancy.
