Normal number of ejaculations per month for men

Ejaculation of male friends is of great significance to their own health. If ejaculation is abnormal, it will lead to some physical diseases of male friends. However, the number of ejaculations per month should not be too many, and should be maintained at a normal level. Do not have too much burden during normal sexual life. Only by relaxing your emotions can the sperm and ejaculation process become smoother.

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.

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.
