[Prolactinoma and pregnancy. Six cases and review of the literature].

Prolactinoma is the most frequent of secreting pituitary adenomas. It is often discovered among women of childbearing-age presenting an association of amenorrhea and galactorrhea. Data in the literature from large series indicate the current risks of interaction between prolactinoma and pregnancy. Risks have been overestimated in the past and it is now recognized that pregnancy can be allowed providing strict follow-up is assured. Dopaminergic drugs have no teratogenic side-effects and are known to allow tumoral control and recovery of fertility in the majority of cases. The use of these medications explains the reduction of indications for surgery. Microprolactinomas are highly influenced by pregnancy and can even lead to tumor retrogression. Macroprolactinomas give complications more often, and require a good tumor control and a rigorous follow-up.
