What Factors Affect Sperm Volume?
The amount of semen refers to the amount of ejaculation in a man. The amount of semen excretion in normal people may vary depending on the abstinence time. Generally, it is 2-6ml, and less than 1.5ml or more than 8ml is considered abnormal.

Simple detection of semen volume
- Normal semen is weakly alkaline, has a special fishy smell, is off-white or milky-white, and contains off-white clots; about 10-20 minutes after being discharged from the body, the clot liquefies itself and becomes a translucent, turbid, thin mucus. If the abstinence is longer, the semen is pale yellow and thicker; if bright red or dark red appears, it may indicate inflammation or reproductive tract damage. Sometimes husband and wife separate for a period of time, sex is frequent and intense after meeting, the pressure of the seminal vesicle is minimized in a short time, and dark red semen will also appear.
Clinical significance of semen volume
- Abnormal results:
- The amount of ejaculation is negatively correlated with the frequency of ejaculation. If the amount of ejaculation is still less than 2ml after 5 to 7 days of abstinence, it is regarded as a decrease in semen; if it is not ejaculated, it is called aspermia. Seminal plasma is a medium for sperm motility, and can neutralize acidic secretions of the vagina, so as not to affect sperm motility. Decreased semen volume (insufficient seminal plasma) is not conducive to sperm entering the uterus and fallopian tubes through the vagina, affecting fertilization. It is common when there are lesions in the prostate and seminal vesicles, especially in tuberculous diseases, obstruction of the excretory duct caused by congenital hypoplasia or inflammation, and there is room for semen in abnormal parts.
- If the amount of ejaculation exceeds 8ml, the sperm is diluted, which is not conducive to fertility. This can be caused by the increased secretory function of gonadotropin in the anterior pituitary gland, which increases the level of androgens; it can also be seen in people who have been abstinent for too long.
Semen volume to be tested
- Less sperm, blood sperm, infertility
Semen volume abnormalities
- Frequent masturbation or frequent sexual intercourse may result in less semen and thinner semen during ejaculation. There are also too few semen, which may be caused by abnormal testicular function, endocrine disorders, seminal vesicle prostate disease, or urethral stricture. You should go to a doctor for treatment. Excessive ejaculation, such as more than 7 ml, is also a pathological condition, mostly caused by seminal vesicle inflammation.
Semen volume decreased
- 1. Diverticula or urethral stricture in the urethra: Diverticulum or urethral stricture in the urethra will cause some semen to be stored in the diverticulum and not be completely discharged when it is discharged, or it will be blocked above the narrow area and cannot be completely discharged. Phenomenon of semen loss.
- 2. Atresia or stenosis of the ejaculation tube: Sperm and seminal vesicle secretion should enter the urethra and be excreted. The final exit is the ejaculation tube, which means that the ejaculation tube of the vas deferens and the seminal vesicle form the ejaculation tube. With the "gate" of the ejaculation tube, the seminal fluid and sperm can not be discharged or reduced. Therefore, only a small amount of fluid is discharged from the prostate tube that is independently opened in the urethra, and the amount of semen naturally decreases.
- 3. Poor function of seminal vesicles and prostate: The composition of semen can be divided into two parts, a small part is sperm and most is seminal plasma. The seminal plasma is made up of secretions from the accessory gonads such as the seminal vesicles and prostate. If the seminal vesicles or prostate are underdeveloped, inflammation or androgen is deficient and the secretion function is reduced, the amount of semen will be reduced.
