Postmenopausal androgen secreting ovarian tumour: pathophysiological implications; a case report
1Department of Endocrinology and Nutrition, Hospital de la Santa Creu i Sant Pau, Autonomous University, Barcelona, Spain.
Summary
This study investigated chronic testosterone's effects on the hypothalamic-pituitary axis in a postmenopausal woman with an ovarian tumor. The findings reveal testosterone's impact on hormone regulation, offering insights into hyperandrogenism.
Area of Science:
- Endocrinology
- Reproductive Medicine
- Oncology
Background:
- Hyperandrogenism in women often disrupts the hypothalamic-pituitary-ovarian axis.
- The precise impact of chronic androgen excess on this axis remains unclear.
Observation:
- A postmenopausal woman presented with recent-onset hirsutism and hyperandrogenism.
- She had elevated serum testosterone and suppressed gonadotropins (FSH and LH), with a low LH/FSH ratio.
- An intraovarian testosterone-secreting tumor was identified and surgically removed.
Findings:
- Post-surgery, testosterone levels normalized, and gonadotropins returned to expected postmenopausal ranges.
- The patient's unique hormonal profile (low LH/FSH ratio) may be due to hypoestrogenism and/or lack of inhibin.
- This case provides a model to study testosterone's isolated effects on LH and FSH secretion.
Implications:
- Understanding the isolated effects of testosterone on the hypothalamic-pituitary axis.
- Provides a unique model for studying hormonal regulation in the absence of estrogens and inhibin.
- Contributes to the understanding of virilizing ovarian tumors and hyperandrogenism management.
