title: Controlled ovarian hyperstimulation and IVF pregnancy prognosis.
abstract: IVF (in vitro fertilization) often represents the ultimate step in our attempt to treat infertility. Nowadays this method is more and more used, couple's expectations are higher and higher, so that optimizing the chance that one IVF pregnancy became a healthy newborn child is becoming an important issue. In this study we analyzed the controlled ovarian hyperstimulation impact on IVF pregnancy prognosis. We studied 307 patients who had IVF fresh procedures in "Panait Sirbu" Clinical Hospital of Obstetrics and Gynecology - Department of Assisted Human Reproduction between 01.01.2008 - 31.12.2010 and obtained pregnancy; pregnancy rate according to our statistics is 34%. For statistic analysis we used the odd Student test. Our data proved better results (defined as a better birth/abortion ratio) for the patients where recombinant FSH was used towards patients where highly purified urinary gonadotropin or the combination of the two drugs was used. Our statistical data also proved that none of the variables: age, BMI (body mass index), endometrium thickness, number of oocytes, number of embryos or number of days of stimulation is a favorable variable for this better result, but the number of units of gonadotropin is a favorable variable for a better birth/abortion ratio. We consider that our data gives an interesting perspective upon the connection between controlled ovarian hyperstimulation and pregnancy outcome, especially these days when tendencies are to obtain as many oocytes in one procedure as we can, which often means to use high doses of gonadotropin.
