Human Uterine Lavage: First Live Births from In Vivo Conceived Genetically Screened Blastocysts.
Observational study in Advances in therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03426007 (Controlled Ovarian Stimulation and Human Uterine Lavage), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
introductionWe wish to report the first live births from genetically screened human euploid blastocysts obtained by uterine lavage. The embryos transferred to infertile women were previously obtained using a novel fully automated uterine lavage catheter and fluid recovery device developed for this indication. The objective of this portion of the research was to confirm embryo implantation and live births with these unique in vivo conceived blastocysts obtained by uterine lavage.
methodsIn vivo conceived embryos recovered by uterine lavage 5 days after intrauterine insemination were available for embryo donation. In vivo embryos were the result of prior controlled ovarian stimulation cycles in oocyte donors and intrauterine insemination with donor sperm. An observational case series of nine embryo transfer procedures was performed at an outpatient fertility center. One to two embryos were transferred to eight infertile women since one woman had two separate embryo transfer procedures.
resultsNine embryo transfer procedures were performed with 14 blastocysts in eight women resulting in a blastocyst implantation rate of 36% (5/14) and live birth rate of 44% (4/9). Five infants have been born from the four delivered pregnancies with one set of twins.
conclusionsThis is the first report of live births from genetically screened human euploid blastocysts obtained by uterine lavage. The nonsurgical uterine lavage office procedure represents the only current approach to obtain in vivo conceived embryos and can provide a benchmark for comparison to standard in vitro cultured blastocysts. Live births of in vivo conceived blastocysts represent the validation that the nonsurgical uterine lavage procedure allows simplified access to naturally conceived embryos without performing the surgical procedure of an oocyte aspiration. Owing to its simplicity, uterine lavage may be useful in screening embryos for preimplantation genetic testing for aneuploidy in fertile and infertile couples.
