Testicular Cancer and Male Fertility

testicular_cancer_fertility_blog_Feb09.jpg US News and World Report has released a report done by researchers saying that infertile men are at higher risk of developing testicular cancer. The question many are wondering is it the infertility treatments causing this increase or simply a random link between infertile men and testicular cancer. At this point in time the data is not certain of such causes, but the thought is that an underlying environmental factor is linked to both infertility and cancer in men. The article said, "They analyzed data from more than 22,500 men in couples who sought fertility treatment between 1967 and 1998, and also examined cancer registry data. Thirty-four of the men developed testicular cancer within a year of seeking treatment for infertility. The researchers calculated that men in couples seeking fertility treatment were 1.3 times more likely to develop testicular cancer than those of the same age in the general population. Men with male infertility factor were 2.8 times more likely to develop testicular cancer than other men." Testicular cancer has become much more prevalent in the last 30-50 years, especially in industrialized countries like the US. If it is an environmental germ or factor, it is adversely affecting fertility as well.
