Summary

This study looked at over 1,800 frozen embryo transfer cycles to see if a woman's body mass index (BMI) affects whether the transfer can be done as planned and if it leads to pregnancy. Researchers compared obese and non-obese women using different hormone preparation methods. The goal was to understand if weight influences treatment success and cycle cancellation rates.

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Women undergoing assisted reproductive technology (ART) with frozen embryo transfer (FET) at a tertiary fertility center were retrospectively identified. The study population included adult patients who underwent endometrial preparation using one of the following protocols: modified natural cycle with ovulation trigger, stimulated cycle, or hormone replacement therapy (HRT). Participants were categorized according to body mass index (BMI) into obese and non-obese groups for comparative analysis of embryo transfer feasibility and reproductive outcomes.

Ages

18 to 45 years

Sex

Female participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
