Gonad Fun Fact

Guys, did you know that your gonads are not as symmetrical as you think? Testicular cancer is slightly more common in the right than the left testis.

In fact, the way in which blood drains from the testes is a bit different. The left testis drains into the renal vein which then connects to the superior vena cava. However, the right testis drains directly into the vena cava. This suggests that vascular differences might account for laterality phenotypes observed in the human population.

Now you know!
