The IVF procedure

The in vitro fertilization is an assisted reproductive technique, in which the fecundation of the ovules takes place outside the human body. After the medication therapy, the ovaries provide more mature ovules, which are collected through puncture. The ovules are fecundated with the partner’s spermatozoids in laboratory and the embryos are incubated for 2-5 days. The best embryos are selected in order to be inserted into the uterus.


In 1978 Louise Brown was born, the first test tube baby. The number of IVF babies have been constantly increasing ever since. Until now, no differences were noticed between these babies and the ones conceived naturally, from the viewpoint of malformations percentage and intelligence. The IVF procedure reports depend on several individual factors. Each patient responds differently, uniquely to treatment and the reasons for which IVF is recommended can vary.


The main situations for which IVF is recommended are: obstruction or bilateral affecting of uterine tubes, severe masculine infertility, endometriosis, and infertility of unexplained causes or lack of response to previous treatment. Using donated oocytes or surrogacy also require the IVF technique.


Exactly as in the case of fertile couples, 3-4 treatment cycles may be needed for obtaining a pregnancy, the IVF technique can be repeated and adjusted depending on the previous result. High quality embryos that have not been transferred into the uterus can be conserved or donated.
