Health is the last thing men think about during ejaculation. In fact, the color, consistency, and smell of semen help us monitor our health. The external finished sperm product contains only about 10% of the sperm produced. The seminal fluid also contains enzymes, vitamin C, calcium, proteins, sodium, zinc and fructose. What does semen look like normally? Semen normally looks like a cloudy white or gray liquid. It is characterized by a jelly-like consistency and a chlorine-like odor (although this can vary from man to man). The average volume of seminal fluid produced during ejaculation varies between 2 and 5 ml. Blood in semen – do I have cancer? Blood in the semen (known as hematospermia) is a worrying symptom for any man, but it is rarely a serious illness. The most common cause of blood in the semen is due to fragile blood vessels with weak walls in the sperm storage area. This is a completely normal process and within 1 to 2 days the sperm should return to its normal color. If this symptom persists for more than a few days, it may be an indication of infection, trauma or a malignant process (rare), and it is necessary to see a doctor. NEWS_MORE_BOX When should we seek immediate consultation with a medical specialist? If the seminal fluid acquires a yellow or green color, this will be an unpleasant sign characteristic of a sexually transmitted infection. The appearance of a seminal infection may cause it to change color, look and smell unpleasant. Other symptoms common to sexually transmitted infections in men include sores and blisters on the penis, pain and burning when urinating, itching and swelling. However, sexually transmitted infections are often asymptomatic. And if there is no sperm at all? It is called a “dry orgasm” – a common symptom among men who have reached their sexual climax. For most young men, this is not a cause for concern. Often this is the result of repeated orgasm. However, in men who have undergone prostate surgery, radiation therapy, or other treatments to the prostate area, this may be a sign of retrograde ejaculation.
