Abstract
Objective: To describe three cases of azoospermia in patients with oligospermia after clomiphene citrate (CC) intake.
Design: Case report.
Setting(s): Academic medical center.
Patient(s): Three patients with oligospermia.
Intervention(s): Three oligospermic men used CC, resulting in azoospermia.
Main outcome measure(s): Semen analysis after CC use and after discontinuation of CC.
Result(s): Three patients were sent to our clinic for investigation of their azoospermia after use of CC. They had severe oligozoospermia (sperm concentrations of 3.4, 2.8, and 4.1 x 10(6)/mL, respectively) before treatment with CC. These patients were re-evaluated with two new semen analyses, showing azoospermia. After 3 months without use of the drug, the mean sperm concentration was 2.5 +/- 1.1 x 10(6)/mL.
Conclusion(s): The benefits of empiric treatment with CC must be balanced with the possible undesirable effects, such as azoospermia.
