ABSTRACT

In vitro fertilization was developed as a treatment to solve tubal disease, which meant, women who by infectious processes, inflammatory diseases or surgical events were infertile. Unable to regain tubal function via surgery, it was thought to fertilizing an egg in a laboratory and transfers the resulting embryo into the uterus, with a later achievement of a viable intrauterine pregnancy. It was until 1976, when Edwards and Steptoe finally manage to conclude the first in vitro fertilization birth, culminating a time of research and beginning a development and innovations era, which until today, has not ended. Material and methods: We performed a retrolective, descriptive and cross sectional study, which included those patients with a medical justified indication that underwent fertility treatments, reported on series XI and XII in the Clínica de Fertilización Asistida. Stimulation protocols: the basic protocols are Down Regulation (Long) and Short with Antagonists, both using ovary synchronization with oral contraceptives. The fertilization, egg injection and embryonic development was carried out in the conventional manner, so as to in vitro fertilization and intracytoplasmic sperm injection, with a short development in 3 days, or extended to 5 days. All embryo transfers were performed under ultrasonographic control. Results: The rates of fertilization, development and pregnancy were comparable with the results reported on the best first world countries. Conclusions: Success rates in our extended culture group were relevant for the favorable high rate pregnancy set, high number of singletons, lower rates of twin sets and a significant decrease in multiple pregnancies. Finally we reported no cases of severe ovarian hyperstimulation.
