چکیده
o p w t t n p p to 30% of couples who are unable to conceive are etermined to have unexplained infertility (1). Traditionally, his diagnosis is made only after the basic infertility evalution fails to reveal an obvious abnormality. The basic evalation should provide evidence of ovulation, adequate sperm roduction and patency of the fallopian tubes. However, ven the most sophisticated diagnostic assessment cannot eveal all possible abnormalities. Therefore, unexplained nfertility appears to represent either the lower extreme of he normal distribution of fertility, or it arises from a defect n fecundity that cannot be detected by the routine infertility valuation (2). Couples with unexplained infertility suffer rom both diminished and delayed fecundity. In a review of tudies of unexplained infertility, the average cycle fecundity n the untreated control groups was 1.8% in 11 nonrandomzed studies and 3.8% in 6 randomized studies (3). Pregancy rates are lower with increasing age of the female artner and duration of infertility (4).
