Men with infertility more likely to develop aggressive prostate cancer

According to a new study, men with infertility issues may be more likely to develop more aggressive forms of prostate cancer than fertile men.

Researchers at the University of Washington School of Medicine in Seattle have found that infertile men who did develop prostate cancer were more than two-and-a-half times more likely to develop high-grade or aggressive prostate cancers, which are more likely to grow and spread quickly, than fertile men.

Researchers say previous studies on a possible link between male infertility and prostate cancer risk have produced conflicting results, with some showing men who have children have a lower risk of developing the disease and some showing no increased risk. However, they say the number of children a man has may not accurately reflect his own fertility.
