Sperm is a collection of products that produce six male sex hormones . It is released during ejaculation in the form of a heterogeneous turbid liquid with a slight smell of chlorine. The color of sperm in a healthy person is usually white with a grayish tint, but there may be other shades of it - milky or yellowish.
It is known that this fluid is quite viscous and transparent. Its main volume falls on the seminal fluid, which contains carbohydrates, proteins, hormones, vitamins and other substances. Spermatozoa, carriers of heredity data, which make up only five percent of the amount of seed, give it a milky tint. Thus, the color of sperm, including transparency, depends on the number of sperm in it. Therefore, a change in normal color can become a concern for men, since a deviation from the norm most often indicates the presence of a disease.
First of all, the color of seminal fluid depends on what lifestyle a man leads. If he uses certain medications, in particular antibiotics or vitamins, then he may have a yellowish sperm.
Also, some foods containing artificial or natural dyes can change the color. For example, the use of beets in large quantities contributes to the acquisition of ejaculate reddish color.
Moreover, human sexual activity also plays an important role. After prolonged abstinence, sperm may acquire a yellowish tint, and if several sexual intercourse were performed during the day, it may become more transparent. Also, with active sexual intercourse, microtraumas can occur in the urethra, as a result of which the blood from the capillaries enters the seminal fluid and gives it a pink color. This phenomenon usually disappears after a few days, but if the reddish color of the sperm persists for a long time, you should consult a doctor.
But the discoloration of the ejaculate is not always associated with harmless reasons, sometimes this may indicate the presence of a disease. Therefore, if any doubt arises, it is recommended that you immediately contact an andrologist or urologist and take an analysis such as a spermogram. This study allows, having studied including sperm color, to identify possible health problems.
Let's look at a few examples. So, a clear replaceable fluid may indicate azoospermia (male infertility), a red or pink shade - hemospermia (inflammation of the urethra or prostate gland), and a greenish color - the presence of infection in the prostate, scrotum or seminal vesicles, as well as the presence of STDs. If a dark color is observed, it can be inflammation of the testicle or vas deferens, and in some cases, prostate cancer.
Thus, the normal color of sperm is white-grayish, milky, sometimes yellowish. Any deviations can be caused by various reasons, so do not delay the visit to the urologist.
