Abstract
Infertility is often a difficult and stressful condition for both clinicians and patients to address. The possibility of being childless often threatens both the male and female partner’s self-esteem. In addition, clinicians are often unfamiliar with the plethora of diagnostic tests currently available, and the interpretation of those tests required to develop a rational management plan. Pregnancy rates by intercourse in normal couples are approximately 20–25% per month, 75 % by six months, and 90% by one year.
After one year of unprotected intercourse approximately 15% of couples of unknown fertility status are unable to conceive. In approximately 30% of these couples, infertility is due to a significant male factor alone, whereas combined male and female factors are present in an additional 20%. Thus, a male factor is involved in approximately 50% of infertile relationships. It is important to realize that 25–35% of infertile couples without treatment will conceive by intercourse at some point in time
