The Science Behind Male Orgasms (part1)

Orgasms in men are not as simple experience as many might think. In contrast to women, the major purpose of the male orgasm is sperm ejaculation. So pleasure and the insemination function come inseparable from each other. While this is the general case, it should be noticed that men do not always ejaculate when an orgasm occurs.

The study of processes behind male and female orgasms began as far back as in the 1950s, when Alfred Kinsey conducted his first examinations on the subject. Since then, a huge advancement was made in understanding this interesting phenomenon. Researches have been addressing both emotional and physiological aspects, so today, one can state that we know pretty much when it comes to what factors promote or impede the male orgasm.

Physiological Aspects

Testosterone, the male-specific hormone, which is produced by a man’s testicles, plays a key role, namely boosting male libido (sexual desire). Consequently, sexual arousal causes the erection, with the orgasm being a culmination of the entire process. Once the ejaculation has taken place, the arousal plummets. Low testosterone levels tend to lead to decreased energy and poor mood in an individual making him more reluctant to respond to mental or physical sexual stimulation.

To summarize, a man, to achieve arousal, requires only physical stimulation, while a woman, in general, will need both mental and physical stimulation to get to the ultimate point.

To extend the comparison, the orgasm in men is much shorter and comes much faster than that in women. On average, the male orgasm lasts for only 5 to 10 seconds, while the female orgasm can last 15 seconds and more. According to some female respondents, they can experience orgasms up to one minute long, which is absolutely impossible for men, even in theory.

As a culmination of his orgasm, a man ejaculates semen, which consists of the seminal fluid and sperm cells, the former acting as a carrier, and the latter serving the purpose of impregnation. The average amount of semen shot at a time is about a teaspoon.

Major Phases of Men’s Orgasm

There are four major phases that can be classified when it comes to male orgasms. They can vary in intensity and duration in different men. Nevertheless, the process should always go the same path discovered by Virginia Johnson and William Masters in 1966.

  • 1. Arousal

During this stage, a range of external and mental factors urge a man’s brain to produce acetylcholine, a neurotransmitter, which ultimately makes the penis’s blood vessels expand rapidly to accept and hold more blood. As a result, the erection occurs, which is accompanied by hurried breathing, increased overall muscle tension across the whole body and the scrotal sac retraction.

  • 2. Plateau

This is the second phase occurring right before the orgasm. It is characterized by the fact that the voluntary pelvis thrusts become mainly involuntary and increase in speed and intensity. The heart rate soars up to 150-175 beats per minute at this stage, while both the body temperature and the blood pressure tend to rise too. From the urethra, the first seminal fluid traces may leak during this period of time, which has its physiological destination. On average, the plateau stage lasts 30 seconds to two minutes.
