Jakarta, one of the treatments for prostate cancer is brachytherapy, which measures the initial response of prostate cancer by implanting radioactive granules in prostate cancer cells. The study finds radioactive grains can damage sperm DNA. This damage seems to be enough to make a man become sterile.
Previous research has found that brachytherapy is less likely to cause erectile dysfunction compared to external radiation or surgical removal of the prostate gland.
On the other hand, research shows that men who undergo brachytherapy often become sterile. But there are also patients who had become a father.
"Today more and more prostate cancers diagnosed in younger men, and many more are diagnosed increasingly in older men who still want to have children," said the researcher, Dr. Neil Fleshner as reported by HealthDay, Monday (02/06/2012).
Dr. Fleshner is also chairman of the department of urology at the University Health Network in Toronto, Canada, and colleagues studied semen samples from five men who had undergone brachytherapy for at least one year.
All of the participants younger than 55 years. Researchers compared the semen samples with data from healthy and fertile men, as well as comparing it with data from 7600 men over men infertile.
Overall, 46% of brachytherapy patients have sperm of DNA damage that is large enough to make a man become infertile. In comparison, only 13% of the sperm of infertile men and 20% of infertile men who suffered similar damage.
"Fifth brachytherapy patients have a high amount of genetic damage in sperm, all of which may have become infertile," said Dr. Fleshner.
In a report published Journal of Urology, researchers then suggested to the man who will undergo brachytherapy for storing sperm in a sperm bank.
Because brachytherapy performed to treat early stage prostate cancer, men who will live it should delay treatment and opt instead to other treatments, methods of active surveillance one of them.
Active surveillance or observation is full of early prostate cancer treatments that do not require medical treatment. This option is performed when the cancer has not shown any symptoms or signs, is expected to grow slowly, and are in one area alone.
One study found that more than 120,000 American men diagnosed with prostate cancer each year and undergo active surveillance therapy. In fact, most of these people end up having to get treatment surgery, radiation or other treatments
