NIH-funded research P01 program project

Age-related changes in FSH sugar tags and how they affect fertility and bones

Official title: Project 4: Age-Related Changes in Gonadotropin Glycosylation and Function

Funded at Wichita State University · NIH-11401807 · Data updated 2026-11-12

A study to understand how changes in the sugar molecules attached to follicle-stimulating hormone (FSH) as women age affect fertility and bone health.

Who could benefit from this research

Could help

Ideal candidates would be women experiencing or approaching menopause where aging affects FSH activity and ovarian function.

Less likely to help

Women without ovarian aging-related fertility concerns may see limited direct benefit.

What this research studies

As women age, FSH changes its sugar makeup and this may alter how strongly it activates its receptor, impacting fertility and bone density. The project aims to create improved tests to distinguish FSH sugar forms and to study how these forms interact with the FSH receptor in the ovary. Researchers will compare different FSH glycoforms in laboratory experiments and in collaboration with other species, to uncover how aging shifts FSH activity and ovarian response. This knowledge could help explain age-related fertility decline and bone loss, guiding future interventions.

Why it matters

Potential benefit: Findings could lead to better diagnostics or treatments for age-related fertility issues and bone health.

How similar studies have gone: Preliminary data suggest glycoforms of FSH have different biological activities, supporting this line of inquiry.
