Every adult man has experienced ejaculation. Although people tend to avoid talking about this topic in their daily lives, it is a normal physiological phenomenon for normal men. Without this phenomenon, men cannot reproduce. Since this topic is embarrassing, no one will discuss this kind of problem in their daily lives. Therefore, many people do not know what it feels like to be healthy and normal, and they always have a lot of worries. So, what is a normal feeling? Let's talk about it below. Ejaculation, a basic biological term, is the reflex action of male animals to eject semen during sexual intercourse. In humans, ejaculation is a series of coordinated actions of various parts of the reproductive system, which eject semen from the penis. It involves a two-step spinal reflex, the primary of which is centered in the lumbosacral spinal cord, and the sensory impulse is transmitted by touch receptors in the glans penis. The neurophysiology of ejaculation is only partially understood. Studies have shown that the dopaminergic system promotes ejaculation while the serotonergic system inhibits ejaculation. The main neural mechanism of ejaculation is somatic innervation, but it also involves nerves and fibers from the autonomic nervous system in the genitals. The autonomic nerve branches of the parasympathetic nervous system mainly control erectile function while the sympathetic and somatic nerve branches mainly control emission and ejaculation. The first step of ejaculation is that the sympathetic nerves send out impulses to cause the smooth muscles of the vas deferens and seminal vesicles to contract, thereby transferring the semen in the vas deferens and seminal vesicles to the urethra; the second step is to use the impulses of the pudendal nerves to contract the transverse muscles at the root of the corpus cavernosum of the penis, thereby ejecting the semen in the urethra. The excitement of the higher parts of the brain also acts on the erection center and ejaculation center of the spinal cord through the descending pathway. Normal human sexual excitement stimulation comes from various senses and affects the spinal reflex activities through the brain. Ejaculation is a complex process that includes erection, ejaculation, ejaculation and orgasm. Erection is due to the swelling and hardening of the penis, and its primary nerve innervation comes from the sacral nerve plexus and the pelvic visceral nerves or erectile nerves. Ejaculation involves collecting semen before ejaculation and transporting it to the prostatic part of the urethra. With the closure of the bladder neck and distal urethral sphincter, the prostatic part of the urethra becomes a reservoir of semen. This will induce ejaculation, that is, the rhythmic ejection of semen through the urethra. The participation of the skeletal muscles of the perineum is essential in this process. Orgasm is a brain-involved, usually pleasurable event and is closely related to ejaculation. The neurophysiology of ejaculation is only partially understood. Research suggests that dopaminergic systems promote ejaculation while serotonergic systems inhibit ejaculation. The primary neural mechanism of ejaculation is somatic innervation, but it also involves nerves and fibers from the autonomic nervous system in the vagina; the autonomic branches of the parasympathetic nervous system primarily control erectile function while the sympathetic and somatic branches primarily control emission and ejaculation. What does it feel like to ejaculate? The strength and distance of male ejaculation are directly proportional to sexual ability. The ejaculation distance of normal healthy men is 20 to 60 cm, and the ejaculation distance of strong young men can reach 1 meter. However, with the decline of sexual ability and the increase of age, the reaction during orgasm will also degenerate. The strength and distance of male ejaculation gradually decrease and shorten, and the semen does not spray out, but overflows or flows out, which is called weak ejaculation. The ejaculation distance of men after the age of 50 is about 10 to 20 cm, or even shorter. People with weak ejaculation are often accompanied by a decrease or disappearance of pleasure, or even no feeling of ejaculation. A man's ejaculation ability reflects his sexual ability, sexual feelings and physical condition to a certain extent. The more powerful and farther the ejaculation is, the better the health and physical fitness of the man is, and he will definitely perform well in his sexual life. Many men with low sexual function and decreased libido, especially middle-aged and elderly men, often complain to doctors that they have lost their ability to ejaculate and used to "ejaculate" out. After knowing what the feeling is, friends who feel abnormal should seek medical attention in time to avoid more serious consequences. More importantly, if you want to be healthy, you should take good care of your body at ordinary times. You can't do it frequently to meet your temporary needs, thereby destroying your body. This will not be worth the loss. It will affect your future life for a lifetime, and in serious cases it will even destroy the happiness of your family. |
