Steve Nakajima, MD- In vivo conceived embryos recovered by nonsurgical uterine lavage

In a series of 69 cycles of superovulation followed by IUI, uterine lavage recovered 48 embryos in 25 (36.2%) of cycles.

Santiago Munne, PhD- First Analysis of In Vivo Blastocysts

Uterine lavage performed after insemination successfully recovered in vivo blastocysts. Using Next Generation Sequencing (NGS) we performed the first chromosomal characterization, where 27.5% were euploid.

Previvo 2017 In Review

Through these efforts we have achieved a scientific first: History’s first preimplantation chromosomal screening (PGS) with embryos conceived and developed in vivo, without in vitro fertilization (IVF). These results will be published in peer reviewed journals that will be used for submission to the FDA and European regulatory bodies.
