Of course, it can also get you in a lot of trouble, but that s another story. There are many reasons, but chief among them is undoubtedly the fact that researchers have uncovered the fact that sex is actually an excellent way to boost testosterone. That s right it's time to party! For example, one study examined four couples on days that they did and didn't have sexual activity. As you can probably guess, they found that testosterone levels increased on nights after sexual activity and did not on nights where there was no intercourse.
This was verified in a study of senior men that found that more sex corresponded to higher testosterone although there is a chicken-and-egg issue here. It is interesting because as erectile dysfunction sets in, many guys believe they have overdone this area of their life and fall prey to the strange underworld of "overmasturbation" sites and such. However, barring extremes, it is actually lack of sexual activity that can cause middle aged males problems.
You can go too far, of course, and aggravate the prostate and pelvic floor muscles, so some maturity and moderation is always warranted. In fact, this was verified in the same study above [ 4 ] by giving males either Viagra or Cialis and the Cialis group had significantly higher testosterone levels than the Viagra group.
Of course, both of these drugs are PDE5 inhibitors and, therefore, boost nitric oxide, allowing more blood to flow into the penis. However, Cialis has a significantly longer half life. The rule of thumb is that Cialis is effective for about 36 hours for most guys and Viagra for one evening. The researchers noted that sexual intercourse frequency was significantly higher in the Cialis group. This means that the higher testosterone levels of the Cialis cohort was likely because they had more confidence and better erections on most nights than the Viagra group.
The researchers concluded that "as it is unlikely that the two drugs have a different direct effect on the pituitary-testis axis, this effect is probably due to the higher frequency of full sexual intercourse.
So the bottom line is that multiple lines of evidence point to the fact that sex actually increases testosterone through mechanisms that are not thoroughly understood and should be considered one of the engines of increasing one's androgens naturally. However, that is just half of the story. Increasing testosterone can significantly improve your sex life and lowering it can do the opposite.
Testosterone could be called The Sex Hormone for good reason: Many men struggling in the bedroom are struggling because they have low testosterone. When you read the list below, you will see exactly why: Many studies over the years have shown that testosterone is critical to sexual desire. Many males write in saying that at one time in their life they had trouble not thinking about sex and now they almost never do.
This can be very hard on relationships. Low testosterone does not just attack your sex life in the day but at night while you are sleeping as well: One thing that many doctors do not realize: Animal studies have shown that castration decreases eNOS's superpowers by about half  and testosterone restores it back to normal  Of course, the significance of eNOS is that it is the all-important enzyme that governs how much nitric oxide is in your arteries and blood vessels, including those in your penis.
If you've poked around this site much, you know that testosterone strongly affects the male brain. And low T can make you just plain hard to live with.
A number of studies have shown what just about every hypogonadal guy describes: A significant amount of research has shown that low testosterone can also cause or make worse existing depression. Of course, depression makes relationships and sex very difficult. What literally rots the inside of your penis? If you guessed "lack of testosterone," you'd be right on. If this goes on too long, it can result in a nasty condition called venous leakage, where as much blood leaks out of the penis as leaks in.
For more information, read my link on Venous Leakage. Hardening of the Arteries. Low testosterone often attacks every artery in your body, including those in your penis. And that's never good for your sex life.
There are many reasons for this by the way, including the fact that low T increases weight gain, insulin and inflammation - a truly wicked combination. The muscles at the base of penis are particularly important for erections. And they are particularly vulnerable to drops in testosterone levels. These three bad boys are some of the biggest risk factors for erectile dysfunction and many other medical conditions. And it may come as no surprise that low testosterone increases the risk for every one of them.
Inadequate testosterone can also lead to poor sleep quality, which means that the only thing you'll want to do under the covers is put your head on the pillow and crash. Testosterone deficiencies decrease the all-important recuperative REM sleep and other critical sleep parameters. One study showed that low T did this not only by increasing weight gain, which negatively impacts sleep in and of itself, but also through other mechanisms that we do not yet understand.
And, by the way, all of this underscores the fact that the PDE5 Inhibitors will not always solve a man's problems if his testosterone is low enough. A man is definitely swimming upstream without his hormones cooperating. Viagra and Cialis often do not work for other key reasons as well.
