Study of vaginal and uterine microbiome after frozen embryo transfer
Part of Hormones & metabolism, Women’s health & pregnancy clinical trials.
This study looks at how bacteria in the vagina and lining of the uterus change during the “luteal phase” (the time after ovulation and before a pregnancy test) in people using frozen embryo transfers. It may help researchers understand what conditions support embryo implantation and pregnancy in assisted reproduction.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be between 18 and 45 years old
- You are scheduled for transfer of cryopreserved (frozen) embryos
- Your cycle should be a programmed frozen embryo transfer (not a fresh IVF/ICSI transfer)
- Before transfer, there should be no signs that you already ovulated (no mature follicle and/or no progesterone level showing ovulation, as defined by the study)
- You should not have known uterine shape problems or abnormal uterine lining seen on ultrasound or past hysteroscopy

This Phase 3 study tests whether adding micronized progesterone during frozen embryo transfer cycles helps support embryo implantation and pregnancy. You may benefit if your care team is already preparing the uterus with hormone therapy for a blastocyst transfer.
This study looks at whether testing the lining of the womb before a single embryo transfer can help doctors choose the best treatment for you. It compares outcomes for people who had this testing with those who did not, to see if it improves the chance of a successful pregnancy.
This study compares different methods for transferring frozen embryos into the uterus during IVF. It aims to find the best technique to improve pregnancy chances.
This trial explores how natural uterine contractions affect pregnancy success in women using hormone therapy for frozen embryo transfer. It may help doctors understand if uterine activity influences implantation.
This study tests a vaginal treatment (FB301) to see if it helps improve the balance of bacteria in the vagina before a frozen embryo transfer. It may help women who have had a prior failed frozen embryo transfer and have a specific type of vaginal bacterial imbalance.
This study measures changes in your blood immune markers during frozen embryo transfer when the embryo is chromosomally normal. It may help clinics understand what blood immune patterns relate to successful pregnancy in natural or hormone-prepared cycles.
