Based on currently indexed evidence, there is no clinical evidence that gestrinone is an effective treatment for lipedema. A high-quality PRISMA systematic review (2025, high GRADE, low risk of bias) identified zero clinical trials, observational studies or case reports evaluating gestrinone for lipedema, particularly as subcutaneous implants — this is an absence of evidence, so its effectiveness and safety remain unknown. Two narrative/mechanistic reviews (both very-low quality, risk of bias unknown) propose a theoretical rationale for gestrinone in lipedema: as a 19-nortestosterone progestin it is hypothesized to act via PRβ to increase 17β-HSD2, inhibit 17β-HSD1 and aromatase, and thereby reduce local estradiol accumulation, ERα overactivation and adipogenesis in lipedema adipose tissue. However, these reviews present only mechanistic hypotheses and in vitro cell-viability data (MTT in MDA-MB-231 and Huh7 cell lines) and NO clinical intervention data or patient outcomes; they provide theoretical context only and do not demonstrate efficacy. Because no clinical evidence supports it, off-label use (notably via subcutaneous implants) is not justified, and the safety of that route is unstudied. The Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Lipedema Association oppose its use.

This update added two very-low-quality narrative/mechanistic reviews proposing a theoretical rationale (aromatase/estrogen-pathway inhibition) and in vitro cell-viability data for gestrinone in lipedema, but these provide only theoretical context and do not change the absence of clinical efficacy evidence.
Knowledge freshness = share of the 3 indexed evidence sources from the last 5 years (newest 2025, oldest 2024) . Low freshness flags an ageing evidence base — not that the answer is wrong.
Evidence over time

Refining / context
- SCR-LIP-000328 context
This narrative review proposes, on a mechanistic/theoretical basis, that gestrinone (a 19-nortestosterone progestin acting via PRβ to increase 17β-HSD2 and inhibit 17β-HSD1 and aromatase) could reduce local estradiol accumulation and ERα overactivation in lipedema adipose tissue, but presents no clinical intervention data or outcomes in lipedema patients.
DOI:10.9734/jammr/2025/v37i25731 - SCR-LIP-000329 context
This review proposes a mechanistic rationale for gestrinone in lipedema—based on aromatase overexpression in lipedema adipose tissue, with gestrinone hypothesized to inhibit aromatase and block estrogen receptors and adipogenesis—but presents only in vitro cell-viability data (MTT in MDA-MB-231 and Huh7 lines) and no clinical trial demonstrating efficacy in lipedema patients.

Major uncertainty
No clinical trials or patient-outcome data exist for gestrinone in lipedema; the only supporting material is mechanistic theory and in vitro cell-viability data, which cannot establish clinical efficacy or safety. Whether the hypothesized aromatase/estrogen-pathway mechanism translates into any clinical benefit, and the safety of subcutaneous-implant administration, remain entirely unstudied.
