In vitro fertilization (IVF) is a long-term assisted reproductive technique applied to couples who cannot have children. Today, one of the most preferred infertility treatments is “IVF. In cases like infertility, infection, obstruction in the tubes, low sperm quality of the man, weight or aging, the couples can have a baby with the IVF method. In vitro fertilization involves the collection of eggs, which is female reproductive cells and sperm, which are male reproductive cells, and are brought together in the laboratory environment outside of the body to ensure fertilization. The fertilized eggs begin to divide and pass the first stages of development, the so-called embryo, in the laboratory and are placed in the mother’s womb. Pregnancy obtained after this stage is no different from a natural pregnancy. The difference from natural pregnancy is that fertilization is carried out under laboratory conditions and that the fertilized eggs are placed back into the womb. Vaccination treatment can also be preferred before IVF treatment, especially in male infertility. In this method, the collected sperm are transferred into the uterus.
