Since every man produces at least 70,000 individual sperm every minute, you would think male infertility would not be much of a problem. Here are some things you may not know to consider.
In reality, male infertility is the cause behind 40% of all fertility complaints that couples come to a doctor with and 25% of all cases of infertility exist because we've done something wrong. In other words, it could have been avoided.
Smoking, heavy drinking, groin injuries, and even using a computer right on your lap, can have an effect on how well sperm can swim.
Any kind of pleasure you take out of pumping your system full of chemicals – like nicotine, alcohol or drugs of any kind – can make you far less capable of keeping your system supplied with testosterone.
Testosterone isn't just useful in giving you a little boost, come sacktime. Your body needs testosterone to be able to produce a healthy sperm count. But it isn't just illegal drugs that can cause male infertility or at least a problem.
Legitimate chemicals – blood pressure and heart disease medicines, medicines you may take for hair loss or gout, can give you testosterone problems and can put a ding in your sperm count.
It's been reported that when doctors order x-rays of children, often, the x-ray technician just leaves the machine on at full blast. For little boys, this is like a prescription for male infertility when they grow up.
The full blast of x-ray radiation on the family jewels can often render children sterile through life. Why, this can happen even to grown men. Any time a male human goes in for an x-ray, he needs to be given a lead shield for his dangly bits.
Speaking of their tendency to dangle, you need to know that there's a reason nature designed them that way – despite being unpleasantly prone to injury. Sperm needs to remain somewhat cool to do its part.
If you try to subvert nature's design by buying a hot tub or putting the laptop exactly where it shouldn't go, you're doing your attempts at conception a real disservice.
As for the whole boxers versus briefs controversy, apparently there is no difference when it comes to male infertility.
