[Intravaginal culture and embryo transfer].

The intra-vaginal culture and embryo transfer is based on the principle of fertilization of hyman ovocytes in the absence of CO2-enriched air. Ovocytes and spermatozoa are placed in a water-tight tube filled with B2 medium and placed in the vagina during the culture. Once the culture is done, the embryos are replaced in the uterus. The various studies done with intra-vaginal culture and embryo transfer, their results as well as future prospects are reviewed in detail.
