Tamoxifen is used for male infertility and nonobstructive azoospermia (NOA). Although thrombosis complication of tamoxifen on the treatment of breast cancer has been reported repeatedly, there was no literature about the thrombosis complication of tamoxifen treatment on NOA. A 32-year-old man was admitted to hospital for severe swelling of left lower limb, with difficulty walking. He had been diagnosed with NOA 5 months ago and had been taking tamoxifen 20 mg daily for 4 months continuously. After admission, the patient was finally diagnosed of deep vein thrombosis (DVT) with elevated D-dimer level and Doppler ultrasound of the deep venous system. After a series of effective treatments, especially the operation of percutaneous venous thromboembolism aspiration, the patient recovered rapidly and the abnormal laboratory results of coagulopathy returned to normal. Clinicians should warn about the possibility of thromboembolic complications with tamoxifen when treating male infertility.
