The science of male orgasms


The male orgasm is a difficult experience. The main function of the male orgasm is to ejaculate semen, although not all men ejaculate during orgasm. Beyond pleasure, the role of the female orgasm is less clear, although it can help bring the sperm closer to the ovum (ovum).

In the 1950s, Alfred Kinsey, the first scientist to study human sexuality in detail, described orgasm as "an explosive discharge of neuromuscular tension." In the years since this initial research, we have come closer to understanding the physiological and emotional components of the male orgasm and the conditions that interfere with or facilitate it.


The male orgasm is a complex system that involves multiple hormones, organs, and nerve pathways.

The hormone testosterone produced by the testicles plays a central role in enhancing sexual desire (libido), leading to arousal, erection, and ultimately orgasm. In contrast, low testosterone levels not only reduce a man's energy and mood, but also decrease his sensitivity to sexual stimuli, both physical and mental .

That said, men often only need physical stimulation to achieve arousal, while women generally need physical and mental stimulation to achieve the same. Men differ from women in that their orgasms, the culmination of a sexual response, are faster and shorter than those of women.

Generally speaking, a male orgasm lasts five to 10 seconds. For women, it lasts 10-15 seconds on average, although some report orgasms lasting up to a minute (for men this is almost impossible).

Male ejaculation, semen , is made up of sperm and semen, the latter of which contains phosphorylcholine (an enzyme that promotes fertility) and fructose (which provides fuel for semen). The average volume of semen secreted by a healthy man is about one teaspoon.

4 phases of the male orgasm

The path to ejaculation in men is divided into four phases, the third of which is orgasm. Although the duration and intensity of these phases may vary, the experience will be strictly defined.

The model was first exposed by William Masters and Virginia Johnson in their 1966 book Human Sexual Response .


Arousal is the stage in which physical, sensory, and emotional signals cause the brain to release a neurotransmitter known as acetylcholine. This, in turn, triggers the release of nitric oxide in the arteries of the penis, causing them to quickly dilate and fill with blood.

The resulting erection is often accompanied by changes in breathing, increased general muscle tension, and retraction of the scrotal sac.


The plateau is the phase immediately prior to orgasm in which the voluntary thrusts of the body, especially the pelvis, suddenly become involuntary, increasing both in intensity and speed. It is at this stage that the heart rate increases to 150-175 beats per second. minute, accompanied by a marked increase in blood pressure and body temperature.

Traces of semen ("pre-sperm") may leak from the urethra. The discharge of pre-ejaculatory fluid is not just accidental; Alters the pH of the urethra so that sperm have a better chance of survival. In general , the plateau phase lasts from 30 seconds to two minutes.


The orgasm phase is divided into two parts. The first, known as emission, is the stage where ejaculation is inevitable. This is immediately followed by the second stage, ejaculation, during which strong contractions of the muscles of the penis, anus, and the muscles of the perineum help expel sperm from the body .

During orgasm, the brain's reward center (specifically, the cerebellum, amygdala, nucleus accumbens, and ventral tegmental region) fills with neurochemicals that elicit an intense emotional response associated with orgasm.

At the same time, the lateral orbitofrontal cortex , located behind the left eye, is completely closed. It is the part of the brain that plays a central role in judgment and self-control. The effect explains why people often describe orgasm as a state where "nothing else matters."

Resolution and refraction

Permission is the post-orgasm phase when the penis begins to lose its erection. This is often accompanied by a feeling of extreme relaxation or even drowsiness.

Refraction, also known as the refractory period, is the post-orgasm stage in which a man cannot achieve a new erection even with stimulation. In young men, the refractory period can be as little as 15 minutes. In older men, this can last all day.

Multiple orgasms in men

"Multi-orgasmic" is a term used to describe the ability to have more than one orgasm in minutes or seconds . Orgasm may not involve actual ejaculation, but it must include the physiological and emotional components of ejaculation.

The multi-orgasmic state can be classified in two ways:

  • Compressed : Two to four individual and specific orgasms occur in seconds to two minutes.
  • Sporadic – Refraction is delayed and multiple orgasms can be achieved in minutes.

In addition to age, there are generally several factors in men with multiorgasmia. These include using psychoactive drugs, having multiple partners, new sexual partners, and using sex toys to enhance tactile stimulation .

This suggests that the ability to achieve multiple orgasms is the result of a heightened state of arousal, rather than a single hormonal or physiological response.

Male orgasm disorders

Orgasm disorders differ from ejaculation disorders in that the latter refer to the actual release of semen. Common ejaculation disorders include premature ejaculation , retrograde ejaculation (in which semen is redirected to the bladder), and anejaculation (inability to ejaculate).

Don't confuse retrograde ejaculation with dry orgasm. a condition in which very little sperm is released during menopause. Also known as orgasmic anejaculation, dry orgasm usually occurs after bladder or prostate surgery or as a result of low testosterone, blocked seminal ducts, high blood pressure, or an enlarged prostate.

In contrast, anorgasmia is a condition in which a man or woman cannot reach orgasm. Anorgasmia can be caused by psychological problems such as stress, trauma, and performance anxiety, or physical problems such as diabetes, hypertension, and hypogonadism (low testosterone levels).

Anorgasmia can also be caused by surgery on the prostate gland ( prostatectomy ) or by taking certain medications, such as selective serotonin reuptake inhibitors (SSRIs), which are used to treat depression.

Treatment of anorgasmia depends on the underlying cause and may include psychotherapy, drug changes, testosterone replacement therapy, or the use of Dostinex (cabergoline), a dopamine promoter that can alter the hormonal response in men with anorgasmia.

Unfortunately, erectile dysfunction drugs like Viagra (Sildenafil) and Cialis (Tadalafil) cannot treat orgasmic problems because their only function is to increase blood flow to the penis. They do not improve libido and generally do not work without sexual stimulation.

Some men are able to increase both erection and orgasm with digital prostate massage . This is a method in which a finger is inserted into the rectum before and / or during sexual intercourse to manually stimulate the prostate gland. A walnut-sized gland, located in the anterior wall of the rectum, is considered the male G-spot.
