Selective venous sampling for androgen-producing ovarian pathology.

Area of Science:

• Endocrinology
• Reproductive Medicine
• Oncology

Background:

• Diagnosing the source of excessive androgen production in women often requires multiple methods.
• The diagnostic utility of selective venous catheterization for hyperandrogenism remains incompletely defined.

Observation:

• A study evaluated 136 hyperandrogenaemic women, including four new cases and 132 from literature reviews.
• Measurements included serum androgens, diagnostic imaging, and ovarian venous effluent sampling.
• Criteria were developed to differentiate ovarian tumors from other ovarian conditions and to localize lesions.

Findings:

• Peripheral testosterone levels ≥ 4.51 nmol/L effectively distinguished ovarian tumors from benign hyperandrogenism causes (93.8% sensitivity).
• Ovarian venous sampling demonstrated higher ipsilateral testosterone concentrations from single lesions compared to contralateral values.
• A right-to-left ovarian testosterone ratio ≥ 1.44 identified right-sided tumors, and combined with a left-to-right ratio > 15, correctly localized 66% of androgen-producing tumors.

Implications:

• Peripheral testosterone measurements are valuable for identifying ovarian androgen-producing tumors.
• Selective venous sampling offers a complementary role in localizing these tumors, particularly when imaging studies are inconclusive.
• These findings support the integration of biochemical and invasive sampling techniques in the diagnostic workup of hyperandrogenism.
