Changes to a man’s sexual organs with age

Have you ever wondered what is going to happen to your penis, pubic hair, scrotum, the tissues inside your penis change as you age? If you are in your 30s, you would already know that you are not as active in sex as you were in your teens or lower 20s. Right?  Read on, we got more interesting information for you here.

When a man is in 9 to 15 years, the pituitary gland releases hormones that signal your body to start producing testosterone. As a result, puberty starts (and there starts the trouble 😛 ) and you will start noticing changes in your body. Your penis, testes (testicles), scrotum and pubic hair and troubles (for some) will start growing. The levels of testosterone peaks in your late teens to early 20s. Say, 23-24 years of age.  After that, testosterone drops a little bit till you get to 40s. But the amount of drop should be minimal.


Changes to a man’s sexual organs with age

IF you think your testosterone levels have dropped significantly, here is what you can see:

A total lack of interest in sex or low libido problem.

In such situation, our sexologists can help to get back to your healthy and active sexual life.

Ok, now we said that the drop in testosterone levels is minimal as you get to your 40s but did you observe a “significant” change in your sexual health? Why does that happen?

It is because, after 40s, body starts making a protein called SHBG (Sex Hormone binding Globulin). This sticks to the testosterone in the body for some other activities, as a result, the available testosterone for your sexual desire becomes less.

Here are some other changes that you can start noticing as men age:


Pubic Hair

This is the hair on your penis around your grwoing area. This starts thinning and may also turn ‘grey’, interesting, isn’t it?


Size of penis

In short, penis size doesn’t become small BUT, you will see that it is not becoming as large as it used to become. As you age, you add fat in your body due to reduced metabolism, as the fat accumulates above your penis, it starts appearing smaller. Also, there are other reasons, continue reading.


Penis Shape

For some men, as they age, the penis starts curving. This will affect the length and functionality and also the thickness / girth. Such a condition is called “Peyronie’s disease”, lets not get into it as we have already discussed about this problem in the following article

What is Peyronie’s Disease?

Testicles’ size

There are small organs in your testicles that produce sperm. Due to the unavailability of testosterone with age, these organs become small and results in slower sperm production. Also, they shrink due to less ‘work’.

Solution? Hormone replacement therapy – WRONG.

Now, your pituitary gland is not sending signals to make more testosterone like it used to already, if you start injecting artificial testosterone, pituitary gland completely stops sending signals to make testosterone as it already sees testosterone in your body. As a result, these sperm making organs shrink even more.

You should go for Hormone replacement therapy only if your sexologist / andrologist advises you. You should not inject by yourself to get 6 pack or to have more sex, mind that. You will only cause more damage to your sexual organs instead of making them healthier.


The main functionality of your folded skin scrotum is to manage temperature of your testes. That’s the very reason why your balls stick out of your body instead of safely tucking inside it. This scrotum has fine muscles that can contract and expand depending on the temperature resulting in moving the testicles farther down or closer to your body. As you age, these muscles get weak and won’t work like they should be, scrotum hangs more and also, as the skin sags with age, the hanging is seen even more.

Penis function

The nerves in your penis become less sensitive with age. That’s the sad part, which results in trouble having orgasm or even arousal. Along with this, as testosterone levels drop, erection problems starts coming up. Erection problems after 40 years is common BUT if you see this when you are in your 20s, you must visit a trained sexologist. If you are able to get erections, your penis may not be as hard as it used to be but you can still have sex.  Here comes another problem – the ability of your penis to hold blood in it. The more blood it holds, the harder it gets and vice versa. In such cases, you can get erections but may not sustain it.

These are normal and changes to your sex organs is a part of aging. Talk to our sex specialist if you have troubles in your sexual health life, we can surely help  you to stay sexually active for longer. 🙂
