Men typically ejaculate semen that is whitish-gray in color. However, the color and consistency of semen can be affected by a variety of factors, including diet and medications.
Changes in semen color may be a sign of an infection or other medical issue, and should be reported to a healthcare professional. In addition, it is important to continue using alternate methods of birth control until sperm count is confirmed to be zero.
Yellow
Men generally produce whitish-gray to white semen, with a gelatin-like texture. It comes from the seminal vesicles, two glands located behind the penis, and also from the prostate gland.
When a man ejaculates, some of the fluid passes into the urethra (the tube that drains urine from the body), which can cause a yellowish tint in the sperm. This is normal and not something to worry about.
But when a man’s semen turns yellow and clumpy, this can be an indication of a health issue, such as prostatitis or a urinary tract infection. This is a condition called leukocytospermia, and it means there are too many white blood cells in the semen. This may happen because of inflammation, autoimmune conditions, or bacterial or viral infections.
The yellowish color of sperm can also be a sign of sexually transmitted diseases, such as genital herpes or chlamydia. It can be easy to confuse these symptoms, especially since herpes can have a yellowish-green tint.
Other conditions that can cause yellow semen include hepatitis, changes in liver function, certain medications, and infrequent ejaculation. Usually, these issues are not related to vasectomy and should not be a concern unless they are accompanied by other symptoms or persist. Talk to your doctor if you notice any changes in semen color or consistency after having a vasectomy.
Green
While clear, white or gray semen is normal, some men’s semen will turn yellow or green in color. These changes in sperm color are usually temporary and not related to vasectomy. However, the discoloration of sperm may be an indicator of an underlying health issue and should be evaluated by a medical professional.
Infections of the prostate gland or urinary tract can cause a change in the color of semen. This is due to the presence of blood in semen caused by rupturing blood vessels or a blockage of the ejaculatory duct. Likewise, an unhealthy diet and certain medications can lead to a change in sperm color.
Yellow or green sperm can also be caused by the presence of white blood cells in the semen, which is known as hematospermia. This can occur if an individual has a condition like prostatitis or epididymitis, which causes inflammation of the reproductive organs. Alternatively, hematospermia can be a result of the use of certain medications or supplements, including vitamin C, antihistamines or antibiotics.
Vasectomy does not guarantee sterility and it can take several months to see a drop in sperm count. Therefore, it is important to continue using alternative forms of contraception until a semen analysis confirms that there are no sperm present in the ejaculate. It is also recommended to avoid masturbation until a sperm count has returned to a normal level.
Red
If a man sees red or pink traces of semen after having a vasectomy, this is normal and nothing to worry about. This color change, known as hematospermia, is usually painless and self-resolves. Hematospermia may occur in 1-5% of men after having a vasectomy and is a sign that the blood vessels around the seminal vesicles are healing properly.
Other times, the ejaculate can take on a brown or red hue due to a leak or rupture of a blood vessel. A doctor can treat these symptoms depending on the cause. Brown or red semen can also be a sign of prostatitis or a sexually transmitted infection.
In these cases, a doctor may prescribe antibiotics to clear up the issue and help prevent further complications. Men should continue to use alternative forms of birth control until a follow-up semen analysis confirms that the sperm count is zero.
The testicles produce sperm that is transported into a collection of tubes in the back of the testicle called the epididymis, where it then moves on to the seminal vesicles and prostate. These glands make the fluid that is emitted during ejaculation or sexual release, which can contain sperm that fertilize a female egg. It is normal for a man’s ejaculate to occasionally appear different in color or consistency, but it is important to contact a healthcare provider when these changes are consistent or accompanied by discomfort or pain.
Brown
Men who have undergone vasectomy may sometimes experience a change in the color of their semen. While this change in color is often temporary and not a sign of any underlying health conditions, it should be brought to the attention of a healthcare professional for examination.
The most common cause of brown semen is due to bleeding in the prostate gland or seminal vesicles. Infections in these areas also tend to result in brown semen, especially if they are caused by bacterial infections such as chlamydia or gonorrhea. Other causes of brown semen include traumatic injuries to the pelvic region, heavy metal exposure and spinal cord injuries.
Some medications can also contribute to the discoloration of semen. This includes antibiotics, anticoagulants and antidepressants. Additionally, chronic stress can also cause a person’s semen to turn brown.
If a man experiences brown semen, it is important to visit their healthcare provider for an evaluation. A physician will perform a physical exam, take blood samples and run a urinalysis in order to find out what is causing the change in color.
In most cases, a doctor will determine that the underlying problem is not serious and that the semen will return to its normal color once the condition has been treated. If the underlying issue is severe, then the physician will likely recommend more specialized tests in order to provide a diagnosis and proper treatment.
