The technique, first attempted by Steptoe and Edwards[1] and later pioneered by endocrinologist Ricardo Asch, allows fertilization to take place inside the woman's uterus.
The doctor will monitor the growth of the ovarian follicles, and once they are mature, the woman will be injected with human chorionic gonadotropin (hCG).
The eggs will be harvested approximately 36 hours later, mixed with the man's sperm, and placed back into the woman's fallopian tubes using a laparoscope.
Some patients may prefer the procedure to IVF for ethical reasons, since the fertilization takes place inside the body.
The first application of this method in Latin America was held in Argentina on 13 May 1986, and was led by Dr. Ricardo Asch, the treatment was successfully completed with the birth of Manuel Campo Lopez.
