invitro, invivo are the 2process
Answer:
in vitro fertilization and Gamet intra fallopian transfer
Explanation:
~IVF is a method of assisted reproduction in which a man’s sperm and a woman’s eggs are combined outside of the body in a laboratory dish. One or more fertilized eggs (embryos) may be transferred into the woman’s uterus, where they may implant in the uterine lining and develop. Excess embryos may be cryopreserved (frozen) for future use. Initially, IVF was used to treat women with blocked, damaged, or absent fallopian tubes. Today, IVF is used to treat many causes of infertility, such as endometriosis and male factor, or when a couple’s infertility is unexplained. The basic steps in an IVF treatment cycle are ovarian stimulation, egg retrieval, fertilization, embryo culture, and embryo transfer.
~GIFT is an early, and very simple ART (Assisted Reproductive Technology) technique devised in the 1980s to achieve pregnancies in most couples who have not been able to conceive using conventional treatments for infertility (despite having good sperm and normal fallopian tubes). Most infertility patients will have their best chance of pregnancy with some sort of ART procedure, and GIFT is the only ART approach that is completely acceptable to the Roman Catholic Church. The success rate with GIFT is even somewhat higher than with standard IVF (in vitro fertilization), but GIFT can be performed only if the patient has normal fallopian tubes and adequate sperm. For cases with abnormal fallopian tubes, IVF is mandated. For cases with poor sperm, we recommend the ICSI procedure pioneered by us and our Belgian collaborators.
