For one of six couples of childbearing age, fertility is not a force to be turned on at will. Infertility, the inability to achieve pregnancy after a year of regular sexual relations, or the inability to carry pregnancy to live birth, will be experienced by 15% of the population of childbearing age. A recent United States Census Bureau report states that there are now 220 million Americans, and that 66 million (30%) are between the usual childbearing ages of 22 and 40 years. By applying the accepted rate of infertility -15%- we can determine that 10 million people are currently affected by infertility in America (United States Census estimates and projections, based on July 1978).
Medical investigation and treatment of infertility have made great strides in discovering and curing problems of female and male infertility in recent years. It is estimated that 50% to 60% of all infertility can be treated if the couple has access to expert medical care. Some of the most reknowned specialists are claiming cure rates of 70% to 80% for certain types of problems. These cures are not achieved without cost. A couple may incur tremendous physical, emotional, and financial expense -sometimes also years of effort and numerous opinions- before the longed-for baby is born to them.
