Summary

The impact evaluation of ovarian hyperstimulation on coagulation and fibrinolysis in infertile women. Comparative analysis between different ovarian stimulation protocols on thrombin formation and efficiency of fibrinolysis in women diagnosed with infertility.

Detailed description

Infertility is a common problem. Assisted reproductive techniques (ART) increases the chance of getting pregnant by couples undergoing such treatment. Unfortunately, the numer of live births after ART remains still low. Over the past three decades, physicians have tried to improve infertility diagnosis and increase its successful treatment. An effort aimed at increasing effectivenes of diagnosis resulted in hypothesis that one of probable reasons of infertility may be the occurrence of microclots, which worsen implantation and embryos development. There are currently no published studies describing the effects of different ovarian hyperstimulation protocols on hemostasis (coagulation and fibrinolysis). The parameters of thrombin generation and efficiency of fibrinolysis will be evaluated in women qualified for ovarian hyperstimulation. The study may improve the effectiveness of ART.
