Getting married and having children is something that everyone needs to go through. Having children is a matter for both husband and wife, and pregnancy can only be achieved through the combination of the man's sperm and the woman's egg. However, many male friends now have difficulty ejaculating or are unable to ejaculate sperm due to pressure from life or work, or some bad living habits. So how can they ejaculate? 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 release and ejaculation. During sexual intercourse, sensory stimulation is transmitted from the genitals through the sensory branches of the pudendal nerve (a somatic nerve) and through the sacral nerve plexus to the spinal cord. The exact site of control of ejaculation has not been elucidated, but the hypothalamus is thought to be involved. The ejaculatory central efferent impulses in the brain reach the sympathetic trunks of the spinal cord, which travel through the nerve plexus in the upper lower abdomen and the hypogastric nerves to the scrotum, vas deferens, prostate, and other organs involved in male ejaculation. The sympathetic nerves that innervate the neck of the bladder close the neck of the bladder, which is necessary to prevent retrograde ejaculation. Neural information, whether from the higher central nervous system or from spinal reflexes, is transmitted to the sacral nerve plexus and, via the motor branches of the pudendal nerve, to the striated muscles of the perineum, thereby causing ejaculation, which is characterized by rhythmic contractions. These are the bulbospongiosus, ischiococcygeus, and pubococcygeus muscles. The above is an introduction on how to ejaculate. If a man has difficulty ejaculating or cannot ejaculate sperm, he must go to the hospital for examination in time and actively cooperate with relevant treatments. He must not use some drugs indiscriminately in his life. At the same time, he must also pay attention to a reasonable diet in his life. |
