Summary

This study looked at how different doses and methods of giving progesterone (vaginal, under the skin, or muscle injection) affect the structure and function of the uterine lining in women preparing for embryo transfer. 109 healthy women with regular cycles took part, and researchers compared their uterine lining to a natural cycle without extra progesterone. The goal was to understand which approach works best, but no embryos were transferred during the study.
