The cost of semen examination usually ranges from $50 to $200, which varies greatly depending on the combination of examination items, the region and the hospital. Semen examination is mainly used for evaluating male fertility function, diagnosing male infertility and efficacy observation, and can also be used to assist in the diagnosis of male reproductive system diseases, such as gonorrhea, tumors, tuberculosis, congenital testicular hypoplasia and inflammation of the reproductive system. Common semen test items include semen routine analysis, such as semen volume, liquefaction time, semen viscosity, sperm motility, etc.; seminal plasma biochemistry, including acid phosphatase, fructose, lactate dehydrogenase, etc.; semen leukocyte and spermatogonial cell test; anti-sperm antibody test; semen culture; sperm function test, etc., and the cost is usually around 50-200 RMB. Men need to abstain from sex for 3-5 days before the semen test. Having sex too often will cause a decrease in the number and quality of sperms; if there is no normal sex for a long period of time and the abstinence time is too long, it will also affect the test results. When there are abnormalities in the quality of male semen, such as yellowish, reddish or poor liquefaction of semen, it is necessary to go to the hospital, clarify the cause of the disease and then treat it under the guidance of the doctor.
