The researchers believe that the effects of marijuana can impair the body’s endocannabinoid system, which is composed of a cellular network, responsible for the formation of sperm.
The study was conducted by researchers at the University of California at Los Angeles. It 163 people took part in testicular cancer. The control group consisted of 300 participants.
Both groups were asked about marijuana use at some point in their lives.
The results show that 81% of the first group used cannabis. The control group was 70 percent.
Tumors Testino occupy about 1% of all cancers in men and most often affects individuals of 20 – to 40-years old. 90% of testicular cancers originate from germinal (germ) cells in the testes and are divided into seminomas and neseminomi.
Seminomas originate from cells that produce sperm and embryonic neseminomite include cancer, teratoma, and mixed tumors horiokartsinom.
The research team found that the risk of testicular seminoma in marijuana users is twice as big.
Seminoma requires more extensive treatment including radiotherapy and chemotherapy.
The results of the study were published online in the journal Cancer.
