Postmenopausal hyperandrogenism, characterized by excess androgens, requires careful evaluation. Hormonal tests and imaging like MRI and CT scans help pinpoint the source, distinguishing tumors from other causes.
Area of Science:
- Endocrinology
- Reproductive Medicine
- Oncology
Background:
- Postmenopausal hyperandrogenism involves androgen excess from adrenal or ovarian sources.
- Symptoms range from moderate (hirsutism, acne) to severe (virilization, alopecia).
- Rare but critical to exclude are androgen-secreting tumors, including adrenal tumors.
Purpose of the Study:
- To review hormonal measurements and imaging techniques for identifying the origin of androgen excess.
- To assess the utility of testosterone (T), delta 4 androstenedione, 17 OH progesterone, SDHEA, FSH, and LH.
- To evaluate the role of pelvic ultrasound, MRI, and adrenal CT scans in diagnosis.
Main Methods:
- Review of hormonal assays including T, delta 4 androstenedione, 17 OH progesterone, SDHEA, FSH, and LH.
- Analysis of imaging modalities: pelvic ultrasound, pelvic MRI, and adrenal CT scan.
- Correlation of clinical presentation (hirsutism, alopecia progression) with diagnostic findings.
Main Results:
- Rapid progression of hirsutism and/or alopecia, along with elevated serum testosterone levels, suggests a tumorous cause.
- Pelvic MRI is effective for evaluating ovarian and pelvic sources of androgen excess.
- Adrenal CT scans are crucial for identifying adrenal tumors contributing to hyperandrogenism.
Conclusions:
- A combination of specific hormonal measurements and advanced imaging is essential for diagnosing postmenopausal hyperandrogenism.
- Distinguishing between adrenal and ovarian sources, and ruling out tumors, is critical for appropriate patient management.
- MRI and CT scans are valuable tools for localizing the source of androgen excess.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
