Examining the link between progesterone levels and live birth rates

The Correlation Between Luteal Serum Progesterone and Live Birth Rate in IVF - a Prospective Cohort Study (LUT-2)

Observational Regionshospitalet Viborg, Skive · NCT05323513

This study is trying to see if measuring progesterone levels in patients undergoing embryo transfer can help predict their chances of having a live birth.

What this trial studies

This observational cohort study aims to investigate the relationship between serum progesterone levels and the likelihood of achieving a live birth in patients undergoing embryo transfer. Serum progesterone will be measured on day OR+4 and again on the day of embryo transfer, which occurs on either day OR+3 or OR+5. By analyzing these hormone levels, the study seeks to provide insights into how progesterone may influence fertility outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are women undergoing embryo transfer with a BMI of less than 35 kg/m2.

Not a fit: Patients who have undergone a fresh embryo transfer or those who have previously participated in this study may not benefit.

Why it matters

Potential benefit: If successful, this study could help optimize fertility treatments by identifying progesterone levels that are associated with higher live birth rates.

How similar studies have performed: While there have been studies examining hormone levels in relation to fertility, this specific correlation between luteal serum progesterone and live birth rates is less commonly explored, making this approach somewhat novel.
