In vitro fertilization, or IVF, is where an egg is combined with sperm outside the body. The process involves stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilize them in a laboratory liquid. The fertilized egg (zygote) undergoes embryo culture for 2–6 days and is then transferred to the same or another woman's uterus, with the intention of establishing a successful pregnancy.
IVF offers many women and couples a fertility treatment when pregnancy is difficult. For example, some women have extensively damaged fallopian tubes from pelvic inflammatory disease (PID) or from severe intra-abdominal infections. IVF is designed to bypass the tubes by allowing conception to occur outside the body. The fertilized eggs are then introduced into the uterus in the hope of pregnancy.
With Previvo Uterine Lavage, the advantage lies in the ability to develop and recover in vivo fertilized embryos from the uterus of a woman. Once captured by Previvo Uterine Lavage, the embryos can be screened for a specific genetic disease and potentially cryopreserved and replaced when the couple wishes.
Previvo Uterine Lavage is a new choice in recovering fertilized embryos, which are developed in the uterus instead of being developed in a laboratory solution.
