What Causes Fishy Smelling Sperm?

Sperm is essential for reproduction, but it also carries some risks. Many men worry about sperm health because they don’t want to pass on genetic defects or infertility problems to their children.

But what exactly causes fishy smelling sperm?

Some men experience fishy smells during ejaculation, even though they’ve had no prior issues with their semen. This is called postejaculatory emission (PEE), and it affects between 25% and 50% of men. The cause of PEE isn’t known, but researchers believe that it could be caused by certain medications, hormonal changes, or psychological stress.

There are two types of PEE: fishy odor and foul odor. Both types are caused by bacteria in the prostate gland, which produce ammonia. These bad bacteria thrive in warm temperatures, so keeping the area cool can reduce the risk of PEE. Other symptoms of PEE include burning sensation, pain, and urgency. If you notice these symptoms, talk to your doctor.

Sperm Smell Like Bleach

Some men often question their treating doctor that why does my sperm smell like bleach? The most common reason why a man’s testicles produce white or yellowish discharge is due to excess retention of secretions.

In men, the seminal vesicle produces approximately 1 pint of clear fluid daily. Normally, this fluid is released into the urinary tract via ejaculation.

However, if there is excessive retention of fluid within the seminal vesicles, the fluid can spill out of the urethra via ejaculation.

As you know, the ejaculate normally contains sperm cells along with other substances necessary for fertilization. Consequently, some of the contents of the ejaculate may leak out of the urethral opening accompanied by the secretion.

This type of leakage may explain the presence of white or yellowish semen inside the penis. The reasons why such discharge occurs may be due to a variety of causes and should not be considered as normal discharge. Some of them include:

1. Infection – When bad or good bacteria (healthy bacteria) or viruses enter the male sexual organ, they may get trapped within the walls of the seminal vesicles. This may result in the formation of pus which will eventually result in the production of white or yellowish discharge.

2. Cancer – If cancerous tumors develop within the prostate gland, the seminal vesicles may become infected with the tumor cells. This can lead to the production of white or even black semen.

3. Dilation of the Prostate Gland – A swollen prostate gland may also give rise to white or yellowish discharge in the semen.
