(Semen is primarily just a "medium" for transporting sperm. Not only that, but semen also helps nourish and create favorable conditions for sperm to encounter the egg. Semen consists of many components and different factors, including pH. If this index is too high or too low, it indicates an abnormality in the semen and is not conducive to pregnancy)

Normally, semen has a very faint smell due to a combination of substances such as citric acid and calcium. Semen with an unusual smell such as too strong or fishy can be a sign of a male health problem.
