First, read the English article below.

Certain sexually transmitted infections, such as chlamydia and gonorrhea, can cause scarring that interferes with the passage of sperm. Get regularly tested for STIs; if you have one, be sure to get the proper treatment. In most cases you'll be prescribed a course of antibiotics to clear up the infection. This is a swelling of the veins that drain the testicle. It can lead to increased temperature of the testicle and decreased sperm count. See your doctor to determine if this might be affecting your fertility. If so, a surgical procedure can take care of the problem. It's possible that your sperm count is low because your hormones are out of balance. Hormone replacement treatments and medications can change your hormone levels and help you produce more sperm. Talk with your doctor about whether this option is right for you. Hormone replacement treatments and medications usually take at least 3 months to work before you start seeing results.
