Summary
This study looked at how different doses and ways of giving progesterone (vaginal, under the skin, or muscle injection) affect the womb lining in women preparing for embryo transfer. 109 healthy women aged 18-35 took part. The goal was to see which method works best for the womb, but no embryos were transferred because a biopsy was needed for research.
