The ejaculation is a normal physiological phenomenon of men, is the stage end of the man in the “rain”, but also a performance of sexual climax. However, not all men can experience the pleasure of orgasm when ejaculating, and some men are even unable to ejaculate. There are some men who can experience orgasm without the discharge of semen. So there is no need for men to be obsessed with ejaculatory orgasms. So, what does ejaculation really mean? How is ejaculation a process? Ejaculation is a continuous process, and physiological ejaculation contains five parts: semen delivery, initiation, lactation, ejaculation and orgasm, with each stage closely connected. Sexual stimulation is conducted through the dorsal penile nerve and pubic nerve to the sacral nerve, uploaded to the higher centers through the spinal cord, activated by the cerebral cortex, releasing sexual impulses, conducted through the anterior lateral cord of the spinal cord, with sympathetic efferent fibers originating from T10 to L2 of the thoracolumbar spine, encircling the lumbar sympathetic ganglion of the aorta, uniting to form the inferior ventral plexus, and adrenergic nerves forming postganglionic nerve fibers, releasing catecholamines, promoting the genital tract When sexual stimulation accumulates to a certain intensity, the ejaculatory threshold is reached and orgasm is induced, the above muscle groups undergo rhythmic contraction. When the sexual stimulation accumulates to a certain intensity, the ejaculatory threshold is reached and orgasm is induced, the above-mentioned muscle groups undergo rhythmic contraction and the external urethral sphincter muscle relaxes, ejecting the retained semen from the external urethral opening. The above is the entire process of ejaculation, looking at these terminology is not feeling a little dizzy? Don’t worry! The process of ejaculation simply means that the sperm and secretions produced by a man’s testicles will enter the tail of the epididymis and then be transported through the vas deferens to the seminal gland for storage, so that the sperm and secretions and secretions of the seminal gland will mix to form seminal fluid, and then when the brain is excited and the brain center promotes the ejaculatory center and generates signals to the external genitalia, it will lead to the rapid contraction of the seminal gland and enter through the opening of the ejaculatory duct. The ejaculatory ducts enter the prostate and the urethra and expel the semen from the body. This process of sexual response is under the control of the cerebral cortex, and if there is an obstruction in the whole ejaculatory process, or a signal transmission disorder, including nerve center transmission disorder, and peripheral channel blockage, it will lead to ejaculatory dysfunction, such as premature ejaculation, delayed ejaculation, lack of sexual pleasure, hemorrhage, painful ejaculation, non-ejaculation, and reverse ejaculation.
