One hundred and twenty-four cases of unexplained infertility that underwent ovulation induction and intrauterine insemination )IUI( )only one cycle( were evaluated, and divided into 2 groups. Sixteen cases were excluded, as they were unresponsive to the induction ovulation regimen. Group I )n=42( received clomiphene citrate )CC( + dexamethasone, and the control group )group II, n=66( received CC alone. These groups were the same in age, duration of infertility, and body mass index. The clinical pregnancy rates were evaluated in 2 groups by using statistical tests.
