Watery sperm is often associated with signs of infertility. However, what does runny sperm really mean and how do you know if yours is watery or not? Watery sperm is semen that is more watery in consistency and not thicker. Semen itself is a white liquid that comes out of the penis during ejaculation. Each drop of semen contains millions of sperm cells produced by the male reproductive system.
The normal consistency of semen at ejaculation is thick like a gel, with an average volume of 2–5 ml. However, within 15-30 minutes after exiting the seminal canal, the thick sperm will turn watery. Semen that turns watery serves to support the movement of sperm so that it is easier to fertilize the egg. So, this is normal and nothing to worry about. In addition, what is the cause of watery sperm?
1. Pre-ejaculation
During sexual intercourse, usually, there will be dilute sperm that comes out before ejaculation occurs. This clear fluid contains sperm in small amounts and can act as a lubricant.
2. Oligospermia
Watery sperm can be a sign of oligospermia, which is a condition when the sperm count is less than 15 million per 1 ml of semen. This condition can be caused by many factors, such as varicoceles, infections, tumors, and hormonal disorders.
3. Deficiency of the mineral zinc
Men who lack zinc levels in their bodies tend to have a watery sperm consistency. Conversely, men whose zinc levels in their bodies are met have better and more fertile sperm quality.
To determine the quality of sperm and assess the level of fertility of a man, a physical examination by a doctor and supporting tests in the form of sperm analysis are required. Through this test, the number and quality of sperm can be known. The analysis includes:
Semen volume
The average man during ejaculation can expel semen of about half to 1 teaspoon, or at least 2 ml.
Consistency of semen
When expelled, normal semen is initially thick and becomes watery after 15–30 minutes after ejaculation.
Sperm concentration
A normal sperm count is about 20 million or more per ml of semen. If less, natural fertilization can be more difficult to occur.
