Semen is the liquid that is released from the male urethra during ejaculation. Semen is known to carry sperm and other fluids from the prostate gland or male reproductive organs.

Under normal conditions, semen is a thick and white fluid. However, it can vary in colour and consistency. Watery semen or clear semen can be an alarming indication of fertility problems and low sperm count.

However, ejaculating clear semen or water semen is a temporary condition that has no serious health concerns. And, with lifestyle changes and medical consultation, you can start ejaculating the typical semen fluid again.

If you are wondering, “Why is my cum clear?”, worry not as we’ve got you covered. Read on to find out possible causes, treatments, and related risks of clear cum. 

Causes of Clear Semen 

The main causes of clear semen or water semen include: 

Low Sperm count

A low sperm count is one of the major and the most common causes of ejaculating clear or watery semen. The World Health Organisation defines a low sperm count as producing less than 15 million sperm per millilitre of semen.

The condition of a low sperm count is also known as oligospermia. Having a low sperm count or suffering from oligospermia makes it difficult for a couple to conceive but it is treatable and doesn’t necessarily mean infertility.

There are many causes of low sperm count or oligospermia. These include:

  • Varicocele: Varicocele is the swelling of the veins that run from the testicles to the scrotum. There are no obvious symptoms of varicocele except for a reduction in sperm production or decreasing sperm quality. Varicocele can affect both testicles. It’s a very common condition that affects around 15% of males. Also, a varicocele may or may not lead to infertility issues.
  • Infection: Sexually transmitted diseases like gonorrhea can cause inflammation of the reproductive organ or epididymitis which can lead to a low sperm count.
  • Excess body weight
  • Drug use and excessive alcohol intake
  • Exposure to radiations and toxins
  • Certain medications
  • Klinefelter syndrome is a genetic disorder that can be responsible for a low sperm count
  • Tumors: Both malignant and benign tumors can cause a low sperm count.
  • Hormone imbalances: Hormones that are produced in the testicles, the pituitary gland, or even the hypothalamus are all essential for producing healthy semen. Thus, hormonal imbalances in these glands can cause a low sperm count. 

Retrograde Ejaculation

Retrograde ejaculation is an ejaculation disorder. During ejaculation, semen passes through the urethra and is released out of the penis. However, a dysfunctional bladder can cause the semen to travel backwards into the bladder which leads to retrograde ejaculation. 

People who experience retrograde ejaculation may produce clear cum or watery semen.

Frequent Ejaculation

Another popular cause of “Why is my cum clear?” is frequent ejaculation. If you masturbate several times a day, the quality of the semen after the first release or ejaculation is likely to become thin, clear, and watery. Frequent ejaculation leads to the production of watery and clear semen. Your body needs at least a few hours to produce healthy and thick semen. 

Zinc Deficiency

Another major cause of clear cum is zinc deficiency. Zinc is an essential nutrient that supports many bodily functions including reproduction. Thus, zinc also plays an important role in sperm production. 

Zinc deficiency may contribute to poor semen quality, low sperm count, clear cum, and therefore, infertility. However, too much zinc can also affect sperm quality. That’s why it is important to maintain a balance. 

The body doesn’t produce or store zinc. People have to obtain it from the foods they consume. Popular dietary sources of zinc include oysters, red meat, shellfish, poultry, beans, yoghurts and dairy products, nuts, whole grains, and seeds. 


Sometimes, a pre-ejaculatory fluid is released from the urethra which can be clear cum or watery in colour. This pre-ejaculatory liquid is usually produced before the main ejaculatory semen is released. This occurs during arousal and foreplay. Pre-ejaculation isn’t a cause of worry.

Can clear semen affect fertility? 

As we said, clear semen is often temporary and may resolve itself. However, persistent watery and clear semen can be an indication of low sperm count and lead to infertility. 

Having a low sperm count or oligospermia may not necessarily mean that the person is infertile, but it may still be difficult to conceive. 

Lifestyle Changes to treat clear semen 

Most times, clear semen can be due to dietary or nutrient deficiencies and lifestyle factors. Here are some lifestyle changes that can resolve clear semen and aid in the production of thick and healthy semen:

  1. Maintaining a healthy body and losing excessive fat.
  2. Reducing stress or anxiety and related mental health issues. 
  3. Getting enough sleep, that is, around 8 to 9 hours every night.
  4. Reducing alcohol consumption and drug abuse.
  5. Quitting tobacco.

Your doctor may also suggest you abstain from any sexual activity for a period of time. This is done to notice if the semen consistency changes.

When to see a doctor? 

If your semen colour and consistency are persistently clear and water, it may be wise to consult a doctor or a urologist. A urologist or a medical professional can help you to rule out any possible serious health conditions. 

Also, if your clear semen is accompanied by these symptoms, you should see a doctor immediately:

  1. Unusual discharge
  2. Difficult or painful urination or ejaculation
  3. Fever
  4. Pain or discomfort in the testicles
  5. Pain in the lower abdomen or back
  6. Chills and nausea

If you and your partner haven’t been able to conceive a child after a year of consistently trying, it may be necessary to speak to a professional. A doctor can perform a semen analysis and help you to rule out any serious underlying medical conditions or infertility. 

Don’t worry as a treatment for low sperm count and infertility are easily available. Such treatments usually include laparoscopic surgery or percutaneous embolization.
