Comparison of testicular dose delivered by intensity-modulated radiotherapy and volumetric-modulated arc therapy (VMAT) in patients with prostate cancer

A small decrease in testosterone level has been documented after prostate irradiation, possibly owing to the incidental dose to the testes. Testicular doses from prostate external beam radiation plans with either intensity-modulated radiation therapy (IMRT) or volumetric-modulated arc therapy (VMAT) were calculated to investigate any difference.
