Ejaculation is the release of semen from the body. Premature ejaculation (PE) is when ejaculation happens sooner than a man or his partner would like during sex. Occasional PE is also known as rapid ejaculation, premature climax or early ejaculation. PE might not be a cause for worry. It can be frustrating if it makes sex less enjoyable and impacts relationships. But it happens often and Dr. Shoengold can help.
In the U.S., about 1 in 3 men 18 to 59 years old have problems with PE. The problem is often thought to be psychological, but biology sometimes plays a role.
Ejaculation is controlled by the central nervous system. When men are sexually stimulated, signals are sent to your spinal cord and brain. When men reach a certain level of excitement, signals are then sent from your brain to your reproductive organs. This causes semen to be released through the penis (ejaculation).
Ejaculation has 2 Phases: Emission and Expulsion
Phase 1: Emission
Emission is when sperm moves from the testicles to the prostate and mixes with seminal fluid to make semen. The vasa deferentia are tubes that help move the sperm from the testicles through the prostate to the base of the penis. (When you are talking about just 1 of these tubes, it is called a vas deferens.)
Phase 2: Expulsion
Expulsion is when the muscles at the base of the penis contract. This contraction forces semen out of the penis. Most times, ejaculation and orgasm (climax) happen at the same time. But some men can climax without ejaculating. In most cases, erections go away after this step.
Premature Ejaculation and Erectile Dysfunction (ED)
Sometimes PE is a problem for men who have erection problems (erectile dysfunction or ED). This is when men are not able to get or keep an erection that’s firm enough for sex. Since an erection goes away after ejaculation, it can be difficult to know if the problem is PE or ED. ED should be treated first. Premature ejaculation may not be a problem once the ED is treated.
