Effect of a GnRH Analog on Hepatic Steatosis (EndomMASLD)

February 1, 2026 updated by: Stergios A Polyzos, Aristotle University Of Thessaloniki

Effect of the Pharmacological Cessation of Menstruation With a GnRH Analog on Hepatic Steatosis in Women With Endometriosis

Menopause increases the risk of metabolic dysfunction-associated steatotic liver disease (MASLD), possibly owing to the abrupt lack of estrogen. Gonadotropin-releasing hormone (GnRH) treatment in endometriosis is regarded as a model of pharmaceutical menopause. Thus, the effect of goserelin acetate, a GnRH analog that results in transient menopause, on hepatic steatosis and fibrosis will be evaluated in this study.

Study Overview

Detailed Description

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), which until recently was known as nonalcoholic fatty liver disease (NAFLD), has risen to 30% of the global adult general population, whereas the pharmaceutical interventions against it remain limited. Owing to the epidemiologic and pathophysiologic association of MASLD with obesity, type 2 diabetes mellitus, dyslipidemia and arterial hypertension, the diagnostic criteria for MASLD are similar to those of the metabolic syndrome.

Menopause has been associated with higher MASLD prevalence, with the lack of estrogen being a very plausible pathogenetic contributor to this liver disease. Other pathogenetic contributors of MASLD, including abdominal obesity, increase in insulin resistance (IR) and dysmetabolism of carbohydrates and lipids, are aggravated after menopause, thus adversely contributing to the pathogenesis of MASLD. Regarding the effect of the lack of estrogen on the liver, most to date data are derived from experimental studies, largely showing a favoring effect on MASLD. Epidemiological studies have also shown menopause as an associate of MASLD. However, existing clinical studies are mostly observational, thereby not being able to show a causative association between menopause and MASLD.

Gonadotropin-releasing hormone (GnRH) treatment in disorders such as endometriosis can be regarded as a model of pharmaceutical menopause. More specifically, GnRH analogs, like goserelin acetate, lead to pharmaceutical menopause by suppressing the axis hypothalamus-pituitary-ovaries, thus, causing an iatrogenic, reversible ovarian cessation, which lasts as long as the use of GnRH. The adverse effects of GnRH are generally mild and reversible after their discontinuation.

This is a prospective, interventional non-randomized study, which aims to evaluate the effect of goserelin acetate on hepatic steatosis in women with histologically confirmed endometriosis compared with women with endometriosis that will not receive pharmacological treatment post-surgically.
