Chapter 1 THE PROBLEM AND ITS BACKGROUND This chapter gives an introduction and background on the study. This chapter also presents the statement of the problem, the hypothesis, the significance and scope and limitation of the study.
Introduction Our human species is not exactly known for its willingness to comply with divine instruction. But when God said unto them “Be fruitful and multiply”, they were more than eager to comply. They took the task to heart. They turned a duty into a pleasure. The majority of couples had no problem. A minority, however, were distressed because of delay or inability to conceive and bring forth children. Medicine tried to help them to conceive naturally. There remained, however, a group who could not reproduce naturally without assistance. Infertility affects more than 80 million people worldwide. In general, one in ten couples experiences primary or secondary infertility, but infertility rates vary amongst countries from less than 5% to more than 30%. The increasing prevalence of infertility cases is becoming a major public health problem in developing countries (WHO, 2002). The term “infertility” refers to inability to conceive after having regular unprotected sex. Infertility can also refer to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy full term (Medical News Today, 2009). Though infertility was

traditionally considered a woman’s issue, research has demonstrated that approximately 40 percent of infertility is due in part or entirely to male factors (Essay Empire, 2012).
