Several factors affect the chances of success, including the actual cause of infertility and the response of the patient providing eggs to the drug treatment, but their age at the time of egg collection is the most important factor affecting outcome. For women over 40, the chances of success are reduced. Even if the initial pregnancy test is positive, there is still a considerable risk of early miscarriage. There is usually a drop in pregnancy rate for women who commence treatment after the age of 35.
