Does doing cycling increase sperm, Or testosterone count, levels or it decreases?

Question

Yes cycling may affect male fertlity as it increases scrotal temperature which causes destruction of sperms. Long-distance bicyclists support a significant percentage of weight on the perineal body area between the testis and the rectum. This trauma can affect blood flow to the testis, which can also negatively impact the production of sperm.
You can modify the way the bike by finding appropriate saddle height, saddle shape, and handlebar height, all of which can impact the amount of pressure placed on the genital area. Increasing the width of the back part of the seat, which supports the bony prominences of the pelvis, may help to take some of the pressure off of the genital area.
