Pathway of sperm

To really understand how your everyday life can affect your sperm, you should understand how healthy sperm is made in the first place. A healthy man produces approximately million viable sperm cells each day, although only a tiny few of those will ever go on to try fertilizing an egg. Unlike a woman who will have around mature eggs throughout a lifetime, which can be released from the follicles in the ovaries and potentially be fertilized, a healthy man will produce billions of sperm in his entire lifetime.
