Causes of low sperm count

There are many reasons for less semen volume. It may be related to problems with the prostate and seminal vesicle. We know that semen is mainly composed of two parts, one is sperm and the other is seminal plasma. Seminal plasma is the secretion of the seminal vesicle and prostate. If the semen volume decreases, you should pay attention to it. It may be caused by some disease reasons. The reduction of semen will affect the survival of sperm.

Causes of low sperm count

(1) Dysfunction of the seminal vesicle and prostate: We know that the composition of semen can be divided into two parts, a small part is sperm and the majority is seminal plasma. Seminal plasma is composed of secretions from accessory glands such as the seminal vesicles and prostate. If the secretory function is reduced due to hypoplasia of the seminal vesicles or prostate, inflammation or androgen deficiency, the amount of semen will decrease.

(2) Atresia or stenosis of the ejaculatory duct: Sperm and seminal vesicle secretions must enter the urethra to be discharged, and the subsequent outlet is the ejaculatory duct, that is, the ejaculatory duct is formed when the ampulla of the vas deferens merges with the seminal vesicle duct. With a "checkpoint" in the ejaculatory duct, seminal vesicle fluid and sperm cannot be discharged or the discharge is reduced. Therefore, during ejaculation, only a small amount of fluid is discharged from the prostate duct that opens independently from the urethra, and the amount of semen is naturally significantly reduced.

(3) Diverticula or urethral stenosis in the urethra: Diverticula or urethral stenosis in the urethra will cause part of the semen to be retained in the diverticula during discharge and cannot be discharged completely, or the semen will be blocked above the stricture area and cannot be discharged completely. It is recommended to go to a professional hospital for detailed examination and targeted treatment in time.

(4) Physiological oligospermia is common in patients with frequent sexual activities. For example, some men have sex once or several times a day, so the amount of semen ejaculated each time is relatively small.

(5) Some cases of pathological oligospermia are caused by insufficient testicular function or endocrine disorders.

What is the normal amount of semen?

During sexual life, many people mistakenly believe that the more semen there is, the better the sexual function. In fact, male sexual function is mostly related to factors such as age, levels of male hormones and estrogen, physical strength and mental state, and has no direct correlation with the amount of semen. So, what is the normal amount of semen?

According to the normal semen standards set by the World Health Organization (WHO), the amount of semen a man ejaculates at one time should be between 2 ml and 7 ml, but the amount of semen is closely related to the frequency of sexual life.

For example, some newlyweds have frequent sex during their honeymoon period. In the beginning, they ejaculate a large amount of semen, but later on, it becomes less and less. The reason is very simple. Although the human body has a strong ability to produce sperm and semen, which can usually be replenished 12 days after ejaculation, if ejaculation is too frequent, there will still be a situation where supply cannot meet demand. The lack of semen caused by this situation is certainly not a disease, so there is no need to worry about it. It can be cured by extending the interval between ejaculations. Similar situations may also occur with frequent masturbation or nocturnal emission.

If you do not ejaculate for several times, or the amount of semen is less than 1.5 ml, it is considered oligospermia. It indicates that you may have diseases such as reproductive system infection, tuberculosis, gonorrhea, testicular dysfunction, endocrine disorder, urethral stenosis, etc. If the amount of semen discharged at one time exceeds 8 ml, it is called polyspermia, which is often caused by inflammation of the seminal vesicle and hypersecretion of pituitary gonadotropin.
