In Vitro Fertilization and Embryo Transfer - D2/D3 (Conventional-IVF)
In vitro fertilization (IVF)
In vitro fertilization (IVF) is a process by which an egg is fertilized by sperm outside the body and the resultant embryo is culrured – in vitro for 3 to 5 days in an Incubator. IVF is a major treatment for infertility when other methods of Infertility treatments have failed. The process involves monitoring a woman’s follicular maturation , retrieving oocytes from the woman’s ovaries and letting sperm fertilize them in a fluid medium in a laboratory. When a woman’s natural cycle is monitored to collect a naturally selected ovum (egg) for fertilization, it is known as natural cycle IVF. The resultant embryos , then transferred to the patient’s uterus with the intention of establishing a successful pregnancy.
Are there variations of in vitro fertilization?
Gamete Intra-Fallopian Transfer (GIFT) and Zygote Intra-Fallopian Transfer (ZIFT) are two procedures related to IVF. GIFT is similar to IVF, but the gametes (egg and sperm) are transferred to the fallopian tubes rather than the uterus, and fertilization takes place in the tubes rather than in the laboratory. GIFT also involves a laparoscopic surgical procedure to transfer the sperm and egg into the tubes. ZIFT differs from GIFT in that the fertilization process still takes place in the laboratory versus the fallopian tubes. It is similar to GIFT in that the fertilized egg is transferred into fallopian tubes, and it involves a laparoscopic surgical procedure.
