What is impotence?

Male reproductive health includes many aspects, among which sexual ability is also an important component of reproductive function. The level of sexual ability has a great impact on male fertility. Among them, ejaculation ability is the basis for determining male fertility. Some men will become powerless during ejaculation due to various problems, which seriously affects men's lives. Let's take a look at what disease is ejaculation dysfunction?

It refers to the phenomenon that when a man reaches the peak of sexual desire during intercourse, he does not have enough force to ejaculate into the woman's vagina. From the perspective of sexual physiology, the more powerful the ejaculation, the stronger the sexual pleasure. On the contrary, if the ejaculation is weak, the sexual pleasure will be inferior, and the quality of sexual intercourse will obviously decline. Therefore, weak ejaculation may lead to decreased sexual desire and impotence, thus affecting the relationship between husband and wife.

It is mainly caused by certain lesions in the nervous system and endocrine system. For example, lesions in the brain and spinal cord will hinder the normal function of ejaculation; lesions in the hypothalamus, pituitary gland, and testicles will affect the normal metabolism of sex hormones, and the ejaculation process is inseparable from the effects of sex hormones, which will in turn affect the normal function of ejaculation.

It is mainly due to too frequent sexual intercourse, which causes the central nervous system that controls ejaculation to be overloaded and cannot issue ejaculation commands well, thus causing ejaculation dysfunction. In addition, the quality of sexual life is not high, the man lacks strong sexual excitement, or under the influence of certain psychological factors (such as fear of his wife getting pregnant, fear of sexual intercourse causing pain to his wife, concern about his own sexual function problems, worry that his wife is dissatisfied with his sex life, etc.), which can affect all aspects of sexual activity through the brain and cause ejaculation dysfunction.

There are several possible reasons for the reduction of ejaculation force and semen volume: frequent ejaculation can reduce semen volume; benign prostatic hyperplasia or any urethral injury (urethral stenosis, condyloma acuminatum) can weaken ejaculation force; incomplete bladder closure causes some semen to flow back into the bladder, and only a small amount of semen is discharged from the urethra under the weak force. Retrograde ejaculation may occur after prostatectomy, sympathectomy, extensive pelvic surgery or after taking certain antihypertensive drugs.
