How the hormone LH affects body fat and metabolism as we age

Regulation of Body Composition and Energy Metabolism by LH With Aging

NIH-funded research Icahn School of Medicine at Mount Sinai · NIH-11365790

This project looks at whether increasing LH activity or using LH-like drugs can reduce body fat and raise energy use in adults, especially older people with weight gain or obesity.

What this research studies

Researchers are following clues from lab and animal work that the pituitary hormone LH and drugs that act like it change fat cells and how the body burns energy. They use experiments in animals, fat cell organoids in the lab, and studies of a small-molecule LH agonist (ORG43553) that has been tested in people for infertility. The team measures fat accumulation, fat-cell development, and whole-body energy use including thermogenesis. Their goal is to see if LH-based approaches could be developed into treatments that help lower body fat, particularly in older adults and post‑menopausal women.

Who could benefit from this research

Good fit: Ideal candidates would be adults (21+) with overweight or obesity, particularly older adults or post‑menopausal women experiencing weight gain.

Not a fit: Children under 21, pregnant people, and individuals with conditions that interfere with LH signaling or for whom hormonal treatments are unsafe may not receive direct benefit.

Why it matters

Potential benefit: If successful, this work could lead to new medicines that help reduce body fat and boost metabolism for adults with age-related weight gain or obesity.

How similar studies have performed: Preclinical animal and lab studies have shown LH receptor activation can reduce fat and increase thermogenesis, and the LH agonist ORG43553 has prior clinical testing for infertility, but using these approaches to treat obesity in people remains largely untested.
