| Popis: | This literature review focuses on the use of corifollitropin alfa for ovarian stimulation in assisted reproductive technology (ART) programmes in different groups of patients. Corifollitropin alfa is a gonadotropin drug with prolonged FSH activity. The main difference between corifollitropin alfa and other gonadotropins is the higher level of peak FSH, which leads to the recruitment of more follicles. Another feature is the inability to adjust the gonadotropin dose during the first days of ovarian stimulation. In contrast to traditional indications/contraindications for gonadotropins, the use of cortifollitropin is not recommended in combination with GnRH agonists or in patients with polycystic ovary syndrome.Evidence for the feasibility and efficacy of using corifollitropin alfa in patients with various ovarian response variants in ART programmes has been analysed. Most researchers agree that the use of corifollitropin alfa can be recommended for patients with a presumed poor or normal ovarian response. The use of corifollitropin alfa in patients with a presumed excessive response to ovarian timulation is possible when embryo transfer is not expected: in oocyte donation/oocyte vitrification cycles or in "freeze-all" cycles.A significant advantage of using corifollitropin alfa for oocyte donor patients is the single administration of the drug, which can be done in a medical facility, which reduces the risk of prescription non-compliance.The use of corifollitropin alfa in protocols with GnRH agonists requires further research: firstly, corifollitropin alfa has no LH component and secondly, there is no possibility of ovulation trigger replacement in this protocol if there is a high risk of early ovarian hyperstimulation syndrome. |
