Primary amenorrhea and pituitary adenomas

Area of Science:

• Endocrinology
• Reproductive Medicine
• Neurosurgery

Background:

• Hyperprolactinemia is associated with menstrual dysfunction.
• Prolactin-secreting tumors can cause significant hormonal imbalances.
• Primary amenorrhea requires investigation into underlying causes like hyperprolactinemia.

Purpose of the Study:

• To evaluate the impact of transsphenoidal surgery for prolactinomas on menstrual function in patients with primary amenorrhea.
• To assess the persistence of hyperprolactinemia after surgical tumor removal.
• To determine if surgical intervention can restore spontaneous menses.

Main Methods:

• Retrospective analysis of 210 patients undergoing transsphenoidal surgery for prolactinomas (1972-1980).
• Focus on eight patients presenting with primary amenorrhea, normal thelarche/pubarche, and hyperprolactinemia.
• Sella turcica tomography used for diagnostic findings.

Main Results:

• Only one of the eight primary amenorrhea patients achieved persistent normoprolactinemia and spontaneous menses post-surgery.
• Seven out of eight patients with primary amenorrhea experienced persistent hyperprolactinemia after surgery.
• Hyperprolactinemia interfered with menstrual function but not other pubertal development.

Conclusions:

• Surgical removal of prolactin-secreting tumors can potentially initiate spontaneous menses by resolving hyperprolactinemia.
• Patients with prolactinomas and primary amenorrhea have a high likelihood of persistent hyperprolactinemia post-operatively.
• While prolactinomas affect menstruation, they do not typically impair other aspects of pubertal development.
