Medical Treatments for Hypogonadism do not Significantly Increase the Risk of Deep Vein Thrombosis Over General Population Risk.

ABSTRACT

OBJECTIVE: To evaluate the risk of deep vein thrombosis (DVT) in men treated with testosterone replacement therapy (TRT) or Clomiphene Citrate (CC) and assess other etiologies for DVT as contributing factors. METHODS: Retrospective chart review of 1180 consecutive hypogonadal men who were treated with either TRT or CC. Sixty-four percent had mixed, 16% had primary, and 20% had secondary hypogonadism. RESULTS: Of the 1180 men with hypogonadism, 694 were treated with TRT, while 486 were treated with CC. Overall, 10 of 1180 (0.8%) men were diagnosed with a DVT during the treatment, 9 of whom were on TRT and 1 on CC. Of the 10 men diagnosed with DVT while on treatment, 7 (70%) had potential identifiable etiologies for DVT other than treatment for hypogonadism. None of the men were found to be polycythemic at the time of DVT diagnosis. There was a higher incidence of DVT in men treated with TRT than CC, however; the overall percentages of DVT in both treatment groups were relatively low. There was no difference in the percentages of men found to have other identifiable etiologies for DVT besides being on treatment between the TRT and CC groups. There was not a difference in testosterone levels between the TRT and CC groups. CONCLUSION: The overall rates of DVT for TRT and CC treated patients are relatively low, and the majority of patients with DVT had other identifiable etiologies for DVT. Polycythemia was not found to be a risk factor in the patients diagnosed with DVTs.
