Why is my Sperm Yellow? Causes of Yellow Semen & Sperm

Producing deep yellow ejaculate is unusual but having yellow semen isn’t the worst case on the sperm color chart. Many people wonder what color semen is. These semen color facts will be of help if you have ever asked yourself why your sperm is yellow.

Sometimes a little urine may mix with semen as it travels through the urethra. Urine in semen is one of the causes of yellow semen and yellow sperm. What color should semen be? Semen is mostly whitish in color. Sometimes a man may notice green, brown or even red color in his seminal fluid.

Why is my Sperm Yellow?

Slightly yellow ejaculate on the sperm color chart is normal. It is also okay to have unusual semen color if you are on medication. The term yellow semen and yellow sperm are often used interchangeably, especially on the internet. But what is yellow sperm?

What is Yellow Sperm?

A man releases over 20 million sperms in each milliliter (one thousandth of a liter) of semen. This translates to more than 100 million sperm in each release. Sperms are microscopic and can’t be seen with the naked eye.

Most people refer to semen as sperm. Most questions that regard yellow sperm are actually referring to yellow semen. One of the main causes of yellow semen on the sperm color chart is aging. As men age, the composition of their semen changes. This change is gradual, which is why most men do not even notice their new yellow tinted semen.

Common Causes of Yellow Semen and Sperm

Here are the most common causes of yellow semen and yellow sperm.

Foods That Cause Yellow Sperm

Causes of yellow semen

The mineral sulfur is a key component of the human body. Sulfur, together with calcium and phosphorous, are the three most abundant minerals in our bodies. Sulfur is an antioxidant that helps detoxify the body. It is necessary for healthy skin, hair and joints.

Sulfur reduces inflammation of joints and muscles. It is necessary for healthy and flexible muscle tissues. It also aids in metabolism. Low sulfur levels cause depression and fatigue. Lack of enough sulfur can also cause Parkinson’s and Alzheimer’s disease.

Eating a lot of foods that contain sulfur is among the leading causes of yellow sperm. Sulfur foods also change the taste of cum. Allium vegetables are high in sulfur. Alliums include onions, garlic, chives, shallots and leeks. Reduce your intake of foods in the cabbage family if you notice yellow semen after consuming them. These foods include broccoli, cabbages, kales and turnips. Others are brussels sprouts and cauliflower.

Eggs are high in sulfur, and the egg whites contain most of the sulfur. Protein (fish, meats, poultry, nuts and legumes), especially animal protein is the main source of dietary sulfur.

Urine in Semen: Common Causes of Yellow Semen and Yellow Sperm

Urine Causes Yellow Semen

The prostate gland produces semen. Seminal fluid makes up two-thirds of the ejaculate volume. The bladder holds urine while testicles are the sperm factories. Urine is usually yellowish in color. Urine and semen travel through the same tube (urethra).

The male reproductive system is well designed, such that a man can’t urinate and ejaculate at the same time. Bladder muscles (including the urethral sphincter) contract and shut off the opening between the bladder and the urethra whenever a guy is highly aroused. The clear fluid that you may notice sometimes before ejaculation is not urine but pre-cum (pre-ejaculatory fluid).

Common causes of yellow sperm and yellow semen include conditions that prevent complete closing of the bladder during arousal. These include an enlarged prostate that is mostly caused by aging. Failure of the bladder neck closing during ejaculation can also cause semen to go backwards into the bladder instead of passing into and through the urethra. This is called retrograde ejaculation, a condition which is not common. The presence of urine in semen usually causes slightly yellow tinted semen which shouldn’t worry you.

How Aging causes Yellow Semen

Aging causes Yellow Semen

Older men usually produce lower ejaculate volume. As a result, aging is one of the common causes of yellowish ejaculate.

The more you grow old, the higher the chances of constantly producing yellowish semen. But men may not notice this since the change in semen color due to aging is a gradual process.

Older men also tend to have less frequent sex. Semen usually becomes more whitish and less thick the more frequently a guy ejaculates. Yellow sperm due to aging, however, does not mean the man can’t make a woman pregnant. It’s just a change in sperm color chart!

Infections that are Common causes of Yellow Semen and yellow Sperm

Infections Cause Yellow Semen

The prostate can get an infection. Urinary tract infections (UTI) may cause yellow semen. These infections are easily treated using antibiotics. If you have these symptoms of urinary tract infection or foul smelling semen, just visit your doctor to get the best antibiotics.

Sexually transmitted Infections such as chlamydia and gonorrhea also change the sperm color chart to cause yellow semen. However, sometimes STDs will cause no obvious symptoms. Gonorrhea causes “white, yellow or green thick discharge from the tip of the penis”. This is in addition to other symptoms in men. You should visit your doctor immediately if you suspect that you have an STD.

How Weak Ejaculation causes Yellow Sperm

Less ejaculation is one of the causes of yellow sperm color. This is because yellow sperm is usually old semen. Increase the frequency of sex to reduce yellow semen. In addition, have enough time for masturbation. It might be that your orgasms are too few and they don’t last as long as they should.

A weak erection leads to low ejaculate volume. Consequently, low ejaculate volume is one of the common causes of yellow semen. Weak ejaculation and low semen volume are caused by aging, smoking and excessive alcohol intake. In addition, do more exercises and reduce stress. Learn how to jelq because jelqing is a penis enlargement exercise.

Modify your diet to prevent yellow semen and change your sperm color chart. For quicker results, take semen volume supplements such as Volume Pills. The pills are good for guys who wonder why their sperm is yellow. They increase semen volume for a huge cumshot. They also give you a firmer, thicker and longer-lasting erection.
