Blood and lining tests during IVF cycles to guide endometrial timing
Part of Women’s health & pregnancy clinical trials.
This study looks at “biomarkers” (test signals in your blood or cycle data) to better judge how ready the womb lining is during IVF. It compares two types of IVF hormone setups to see which approach best matches endometrial receptivity and supports successful embryo transfer.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are female and under 37 years old (up to 36 years and 364 days)
- You are a non-smoker and your periods are regular, lasting 25–35 days
- You have been trying for less than 5 years and have had fewer than 3 failed IVF/insemination embryo-transfer cycles
- You have a “normal responder” pattern during stimulation and typical hormone/follicle markers (like day-3 FSH < 10 and 5–15 antral follicles)
- Your IVF plan must use specific embryo-transfer conditions (a single best-quality blastocyst transfer) without cycle cancellation
- You must not have certain conditions, surgeries, or prior diagnoses (like endometriosis/adenomyosis, genetic/metabolic/endocrine disorders, prior OHSS, or major reproductive structure problems)

This trial is testing a new, non-invasive test (called Ora) that checks when your uterine lining is ready for an embryo. It is for women who have had a failed transfer with a genetically normal embryo and are planning a frozen embryo transfer.
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.
This study tests if a blood test measuring tiny molecules (miRNAs) can predict when the uterus is most ready for an embryo. It aims to improve IVF success in women with unexplained repeated implantation failure.
This study looks at immune-related blood patterns and other measurements to better understand why some women have repeated pregnancy loss or repeated IVF implantation failure. If you qualify, your answers and test results may help researchers identify biomarkers that could guide future care.
This study looks at certain blood markers (related to metabolism and blood cells) in women who are going through IVF. Researchers want to understand how these markers might be linked to fertility, which could help improve treatment in the future.
This study follows women who are having IVF/ICSI or frozen embryo transfer (FET) to see how a specific area of the uterine lining relates to pregnancy outcomes. It may help doctors better predict which embryo-transfer situations lead to better results.
