Can a simple uterine flush boost IVF pregnancy rates?
NCT ID NCT06684951
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether flushing the uterus with a low dose of the hormone hCG right after egg retrieval could improve pregnancy rates in women undergoing IVF. Researchers measured immune markers and blood flow in the uterus to see if the flush made the womb more receptive to an embryo. The trial involved 90 infertile women aged 18 to 40.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- human chorionic gonadotropin (hCG)
- What this could lead to
- If successful, this could point toward a simple way to improve IVF success rates by preparing the uterus for embryo implantation.
- What could go wrong
- This is a small, completed Phase 4 study with only 90 participants. The results may not apply to all women, and the intervention may not significantly improve pregnancy rates.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. The patient\'s consent to participate in the research study is crucial for data collection and analysis. 2. Each pair of individuals undergoing IVF/ICSI procedures typically possess grade 1 (G1) embryos during the embryo transfer process. 3. The age range of the female participants varied from 18 to 40 years. 4. Infertility arising from female factors, including issues like blocked fallopian tubes, lack of ovulation, and unexplained fertility challenges, was examined. 5. Male-related factors contributing to infertility were also taken into consideration. 6. The procedure involved the transfer of grade one embryos during a fresh cycle. Exclusion Criteria: Endometrioses, whether clinically suspected or discovered during laparoscopy, are of interest. 2\. Instances of congenital abnormalities in the reproductive system are being examined. 3\. Individuals above the age of forty are under consideration. 4. Individuals who do not possess G1 embryos are also included. 5. Patients with chronic systemic conditions (such as diabetes, hematologic disorders, hypertension, autoimmune disorders of the connective tissue, asthma, thyroid disorders) are a part of the study. 6\. The presence of empty follicles is noted in stimulated cycles where no oocytes were obtained during the aspiration procedure. \-
