Infertility has traditionally been thought of as a woman's problem. But as it turns out, we men don't get off that easily. About one out of every three cases of infertility is due to the man alone, and we're somehow involved in infertility about half the time.
A diagnosis of male infertility can be one of the hardest challenges a man can face. For some, it can be devastating. After all, the necessity of reproduction is one of the few things on which both Darwin and the Bible agree. Not being able to father a child can make a guy feel like he’s failing at one of his most primal responsibilities.
For men, the health benefits of bicycling may involve a troublesome trade-off. While riding a bicycle burns calories and improves cardiovascular fitness, too many hours on a bicycle saddle can compress the artery and vital nerves leading to the penis.

Sperm are made in the testicles. They're then stored inside yards of “plumbing” called the epididymis, which lies on top of each testicle. Sperm are nourished by semen, which is made by glands along the way. When the magic moment arrives, about 150 million sperm are ejaculated in a half-teaspoon of semen through the penis.
This whole process hinges on there being proper levels of testosterone and other hormones as well as correct signaling from the nervous system.
