title: [Infertility: the magnitude of this problem].
abstract: Infertility affects 10-15% of couples at reproductive ages. At the present times, we are experiencing a noticeable increase in the demand for assistance in resolving this problem. Over the past two decades, three important changes have occurred. First, there was the introduction of assisted fertility reproduction techniques which increased the possibilities for effective treatment for infertile couples. Secondly, and partially due to the media attention paid to these techniques, the general public began to learn about these possible treatments which led to a substantial increase in consultations about infertility. The third change is the increase in the number of women over age 35 who solicit medical attention for infertility. This reflects the more advanced age at which marriage is consumed and the postponement of pregnancy when women, either by choice or out of necessity enroll in the labor market. To all of these factors, a slight increase in the proportion of couples considered infertile needs be added.
