Who could benefit from this research

Could help

Adult women with obesity-related infertility or diminished ovarian reserve who are considering IVF.

Less likely to help

Women without obesity-related fertility issues or diminished ovarian reserve may not experience the same benefit.

What this research studies

If you are an adult woman dealing with obesity-related fertility challenges or diminished ovarian reserve, this project will test whether a pulsatile pattern of FSH can improve how your ovaries grow follicles compared to the standard daily injections. Researchers will translate findings from a mouse model to humans and compare hormone output and follicle response between pulsatile and daily FSH delivery across a treatment cycle. The study aims to identify a potential, more effective way to boost fertility potential in this high-need group. Participation would involve a controlled treatment cycle with careful hormonal monitoring and outcomes related to ovarian response.

Why it matters

Potential benefit: If successful, pulsatile FSH could improve ovarian response and fertility outcomes for women with obesity-related subfertility and aging-related ovarian reserve decline.

How similar studies have gone: Preliminary data in obesity-exposed women suggest improved follicle growth with pulsatile FSH, but human-confirmed benefits require confirmation in this trial.
