Reference range:
Viscosity is an important biomarker assessed in a semen analysis that measures the thickness or fluidity of the semen. It plays a key role in determining the semen's ability to effectively transport sperm through the male reproductive system and into the female reproductive tract during fertilization. Normal viscosity allows semen to liquefy within 15 to 30 minutes after ejaculation, which facilitates sperm movement.
Abnormal viscosity, either too thick or too watery, can indicate underlying reproductive health issues. Elevated viscosity, where semen remains thick and stringy, can impair sperm motility, reducing their chances of reaching the egg. Causes of high viscosity can include infections, inflammation of the prostate, dehydration, or hormonal imbalances. On the other hand, low viscosity, where semen appears unusually watery, may suggest conditions like low sperm count or incomplete semen production. This can affect sperm concentration and their ability to survive the journey to the egg.
Overall, semen viscosity is a critical factor in male fertility, as abnormal viscosity may impair sperm function and contribute to difficulties in achieving pregnancy. It is often used alongside other semen analysis parameters to provide a comprehensive picture of male reproductive health. If viscosity is found to be outside the normal range, further diagnostic testing and potential treatments may be necessary to address the underlying cause.

What Healthmatters Members Are Saying
I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
