Summary

Transsphenoidal surgery effectively treated pituitary adenomas in women with hyperprolactinemia, restoring normal prolactin levels and menstrual function in most patients. The study also explored the potential link between oral contraceptive use and these tumors.

Area of Science:

  • Endocrinology
  • Neurosurgery
  • Reproductive Medicine

Background:

  • Hyperprolactinemia, often caused by pituitary adenomas, leads to amenorrhea and galactorrhea.
  • Pituitary adenomas are tumors of the pituitary gland that can disrupt hormone production.
  • The role of oral contraceptives in the development or management of these conditions requires further investigation.

Purpose of the Study:

  • To evaluate the efficacy of microsurgical transsphenoidal excision for pituitary adenomas in patients presenting with amenorrhea, galactorrhea, and hyperprolactinemia.
  • To assess the impact of surgical treatment on prolactin levels and reproductive function.
  • To explore a potential association between prior oral contraceptive use and the occurrence of prolactin-producing pituitary adenomas.

Main Methods:

  • Microsurgical transsphenoidal approach for pituitary adenoma excision.
  • Pre- and post-operative assessment of serum prolactin levels.
  • Monitoring of menstrual function and pregnancy outcomes.

Main Results:

  • Successful normalization of prolactin levels in 5 out of 8 patients; significant reduction in the remaining 3.
  • Resumption of menses in 5 patients.
  • Two patients achieved pregnancy post-surgery.

Conclusions:

  • Transsphenoidal surgery is an effective treatment for hyperprolactinemia-inducing pituitary adenomas.
  • Surgical intervention can restore hormonal balance and reproductive capacity.
  • A potential link between oral contraceptive use and pituitary adenomas warrants further research.
