GLP-1 medication effects on reproductive hormones in obese teenage girls with PCOS

Effects of Glucagon-like Peptide-1 (GLP-1) Agonist in Neuro-reproductive Function in Obese Adolescent Females With Polycystic Ovary Syndrome (PCOS)

Observational Nemours Children's Clinic · NCT07169136

We will test whether GLP-1 medications are linked to changes in reproductive hormones and menstrual cycles in obese adolescent girls with PCOS.

What this trial studies

This observational study will enroll obese adolescent females with PCOS to examine relationships between GLP-1 receptor agonist exposure and neuro-reproductive function. Researchers will collect clinical histories, menstrual cycle data, metabolic measures, and blood samples to measure gonadotropin and sex steroid levels and to characterize GnRH/gonadotropin pulsatility. The study will also examine insulin and other metabolic markers and compare hormonal patterns in participants with and without GLP-1 agonist exposure. Work will be conducted at Nemours Children’s Clinic in Jacksonville and focuses on adolescents at least two years post-menarche who remain symptomatic despite lifestyle changes.

Who should consider this trial

Good fit: Obese (≥95th percentile) female adolescents aged 12–18 years, at least two years post-menarche, diagnosed with PCOS by NIH criteria and still symptomatic despite lifestyle modifications are ideal candidates.

Not a fit: Patients with diabetes or impaired glucose tolerance, abnormal thyroid function, non-classic congenital adrenal hyperplasia, hyperprolactinemia, a personal or family history of medullary thyroid carcinoma/MEN2, pancreatitis, or recent use of metformin, GLP-1 agonists, hormonal contraception, progesterone, or other insulin sensitizers are unlikely to be eligible or to gain benefit from this observational analysis.

Why it matters

Potential benefit: If successful, this could point to GLP-1–based approaches that improve menstrual regularity and reproductive hormone balance in obese adolescents with PCOS.

How similar studies have performed: GLP-1 receptor agonists are proven for diabetes and weight loss and some adult studies show metabolic and reproductive improvements, but direct effects on neuro-reproductive function in adolescents with PCOS remain under-studied.
