Is it good for your body to not ejaculate for a long time?

For normal male friends, proper sex is good for the body. But if you have sex frequently, it will be bad for your health. So, is it good for the body not to ejaculate for a long time? In fact, it is not good. Proper sex can regulate the endocrine system in the body and is also conducive to the harmony between husband and wife. But everyone should also pay attention to other hygiene.

Ejaculation, a basic biological term, is the reflex action of male animals to eject semen during sexual intercourse. For humans, ejaculation is a series of coordinated actions of various parts of the reproductive system, and semen is ejected from the penis.

It consists of a two-step spinal reflex, the primary of which is centered in the lumbosacral spinal cord, with sensory impulses transmitted by touch receptors in the glans penis. The neurophysiology of ejaculation is only partially understood. Studies have shown 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.

The process of ejaculation during male sexual intercourse:

1. When a man is sexually aroused, the blood flow into the penis greatly exceeds the blood return from the penis, causing a large amount of blood to accumulate in the corpus cavernosum of the penis, increasing the pressure, and making the penis hard, erect, thicker, and longer.

2. The contraction of the muscle fibers in the scrotal wall causes the scrotum and the testicles inside to rise and become closer to the body. This is similar to the reaction of the scrotum when it is stimulated by cold.

3. The penis is inserted into the vagina slowly from shallow to deep. At this time, the embrace between the two becomes tighter. As the root of the penis goes deeper into the female body, the space between the two sexes is reduced to a minimum.

4. After the penis and vagina are in close contact and friction stimulation, sexual intercourse enters the continuous stage. The penis becomes further engorged and swollen, showing a dark red color, and the scrotum sticks closer to the body. The testicles also swell due to congestion of blood vessels. A small amount of mucus overflows from the urethra. Some people will have redness on the abdomen and chest.

5. After constant friction between the penis and the vagina, most men reach orgasm within 2-6 minutes and ejaculation reflex occurs. Once the ejaculation reflex is triggered, it is irreversible and cannot be blocked. Ejaculation is intermittent, with an interval of less than 1 second, about 4-5 consecutive ejaculations, and the amount of semen is 1.5-6mL. Less than 1.5 is too little semen and more than 6 is too much semen, both of which are not conducive to the woman's pregnancy. The intensity and force of ejaculation will vary greatly with age, with the peak period being 20-30 years old. The distance of semen ejection is one of the signs of male sexual ability. Along with ejaculation, there will also be slight muscle twitching. Heartbeat, breathing, and blood pressure all reach their peak. Some people's skin redness deepens.

6. After ejaculation, the body begins to recover. Various physiological changes recover quickly: the penis shrinks sharply, and the scrotum returns to normal. The shrunken penis involuntarily slips out of the vagina, entering the male infertility period.
