Low sperm concentration is one of the causes of infertility. When the sperm concentration is less than 15,000,000/ml, it is considered to have reproductive difficulties.

The SP10 protein concentration has a certain linear relationship with the sperm concentration, that is, when the sperm concentration is greater than or equal to 15,000,000/ml, the SP10 protein detection is positive. Therefore, this reagent can be used to assist in the diagnosis of male infertility, and at the same time provide fertility guidance for couples of appropriate age.
