Many factors do influence the success of the treatments. Your age, how long you have been infertile and the reason for it, your life-style, the form of treatment, your body’s reaction to stimulation (i.e. the quality of and how many oocytes you produce), the quality of the semen, the quality of the embryos and the number of embryos to be transferred all influence the probability of pregnancy. Our Live Birth pregnancy rates are way above the Greek national average: 68% baby take-home rate after an exclusive egg donation treatment.
