[Indications of fertilization in vitro (FIV) and intratubal transfer].

Initially developed to treat tubal infertility, in vitro fertilization (IVF) has acquired wider indications when the pregnancy rates have improved. IVF is now offered to couples as the ultimate solution in case of tubal infertility (with Fallopian tubes that are altered or definitively out of action), in case of unexplained infertility or in case of male infertility. In addition, it has been used in endometriosis, in cervical mucus problems or after failure of donor insemination. If at least one tube is healthy (unexplained or male infertility), a gamete intra-Fallopian transfer (GIFT) may be proposed. At the moment, IVF is not only the ultimate therapy but also the ultimate diagnostic test for infertile couples.
