Surgery and Radiation Therapy for Prostate Cancer Cause Lack of Ejaculation
A study of 252 men who were treated for prostate cancer showed that 72% of men lost their ability to ejaculate after radiation treatment. After 5 years, 89% had anejaculation. The mean study age was 65 years.
Since both surgery and radiation therapy are likely to cause anejaculation, it is important that men know about it as they are making decisions on treatment.
