Could a brother or son’s cells affect pregnancy loss?
NCT ID NCT05340556
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This pilot study examines whether cells from a woman’s firstborn son or older brother can be found in her blood and if they are linked to recurrent pregnancy loss. Researchers will take blood and cheek swab samples from 32 women who have had at least three miscarriages. The goal is to gather information for a larger future study, not to test a treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help understand why some women experience recurrent pregnancy loss, potentially pointing toward future diagnostic or treatment approaches.
What could go wrong
This is a very small pilot study (32 participants) that only looks for cells in the blood, not a treatment. It may not find a clear link or lead to any practical changes.
