What is an Erection and Ejaculation?

 

What Is an Erection?
An erection is a hardening of the penis.. Erections occur when sponge-like tissue inside the penis fills up with blood. Usually, an erection causes the penis to enlarge and stand out away from the body.

Erections can go away on their own or after ejaculation which is the release of semen through the urethra, the small hole at the end of the penis.

 

Sometimes guys ejaculate at night while sleeping (wet dreams). Guys may have several erections and arousal periods while in the REM (rapid eye movement) stage of sleep, the level of sleep where most dreams occur.

 

Many erections are caused by sexual arousal, such as watching a sexy television show or fantasizing but many erections seem to happen for no particular reason at all, this is normal.

So if you've had an erection in an odd or embarrassing situation like in the middle of class or school - there's no reason to worry that something is wrong with you. Your body is just acting naturally for a guy your age.

 

Because each person is very different, it's impossible to say what's a "normal" number of erections. Some guys experience many erections each day while others may not experience any. Hormones fluctuate with age, sexual maturity, level of activity, and even the amount of sleep a guy gets.

 

Unless your erections are causing you discomfort or pain, don't worry about how many you get. If you're worried, it's a good idea to talk to your parent or doctor. They can answer your questions and will probably be able to keep you from worrying so much.

Because erections usually happen without reason, there's not much you can do to avoid getting them. Unless the penis is stimulated enough to ejaculate, time is the only thing that will help them go away.

As your hormones settle down and you advance through puberty, the unexpected erections and wet dreams will likely decrease.

 

What is Ejaculation?

 

Once a guy reaches puberty, he will begin producing millions of sperm cells every single day. Each sperm is extremely small. Sperm develops in the testicles in a system of tiny tubes. At birth, these tubules contain simple round cells, but during puberty, testosterone and other hormones cause these cells to transform into sperm cells. The cells divide and change until they have a head and short tail.  They kind of look like tadpoles.

 

The head contains genetic material (genes). The sperm use their tails to push themselves into the epididymis, where they complete their development. It takes sperm about 4 to 6 weeks to travel through the epididymis.

 

The sperm then move to the sperm duct. The seminal vesicles and prostate gland produce a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated.

 

The penis, which usually soft and hangs limp, becomes hard when a male is sexually excited. Tissues in the penis fill with blood and it becomes stiff and erect, this is called an erection. The rigidity of the erect penis makes it easier to insert into the female's vagina during sexual intercourse.

 

When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male's body through his urethra - this process is called ejaculation.
