This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Summary

This study asks whether body fat percentage, measured by a quick bioelectrical impedance analysis (BIA) scale, is a better predictor of IVF outcomes than the traditional body mass index (BMI). Researchers will follow about 200 people undergoing IVF, measuring body composition before treatment and tracking egg retrieval, fertilization, embryo quality, pregnancy, and miscarriage rates. The goal is to see if a more detailed look at body composition could help personalize fertility care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Bioelectrical impedance analysis (BIA) to measure body fat and visceral fat percentage
What this could lead to
If body fat percentage proves a better predictor than BMI, it could help personalize IVF treatment and improve success rates.
What could go wrong
This is an observational study, so it can only show associations, not cause and effect. Results may not apply to all IVF patients.
