Many more couples, however, experience involuntary childlessness for at least one year: estimates range from 12% to 28%.[4] Male infertility is responsible for 20–30% of infertility cases, while 20–35% are due to female infertility, and 25–40% are due to combined problems in both parts.[2][5] In 10–20% of cases, no cause is found.[5] The most common cause of female infertility is ovulatory problems, which generally manifest themselves by sparse or absent menstrual periods.[6] Male infertility is most commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.[7] Women who are fertile experience a natural period of fertility before and during ovulation, and they are naturally infertile for the rest of the menstrual cycle. As the major causes of infertility are sperm abnormalities, ovulation dysfunction, and fallopian tube obstruction, the preliminary adviced investigations for the infertile couple should be focused on semen analysis (to be compared with the WHO reference values [27]), detection of ovarian function by hormonal assay (early follicular FSH and LH levels, and mid-luteal progesterone), and evaluation of tubal patency by hysterosalpingography (HSG) [17-32], (Appendix 3).

Checking testosterone levels is advisable because an elevation above the reference range has a negative feedback effect on sperm production. The pregnancy rate fluctuates from 20-35%, and the expected ectopic pregnancy rate is as high as 20%.
