At present, there are approximately 230 million couples of childbearing age in China, and the incidence of infertility is 8-10%, which means 10 million families are worried about having children.
The main causes of male infertility are genetics, abnormal sex hormones, varicocele, reproductive tract infections, cryptorchidism, bad lifestyle habits, and external pollution. If men know some simple reproductive knowledge and self testing methods, they can conduct effective self testing.
If you gently touch along the spermatic cord from top to bottom and find large, worm like, soft, and convoluted masses inside the scrotum, then be careful, this may be varicocele. It will increase the temperature of the testis, and the stagnation of venous blood will affect the metabolism of the testis, thus interfering with spermatogenesis, resulting in the decline of semen quality.
If there is testicular swelling and pain, and the testicles gradually shrink after relief, it may be testicular torsion or traumatic atrophy after orchitis. This is often accompanied by irreversible damage to spermatid. If the testicles fail to descend into the scrotum and remain in the abdominal cavity, it is called cryptorchidism. Excessive temperature in the abdominal cavity is not conducive to sperm production, and the risk of testicular malignancy is greatly increased.
Observing semen can also partially reflect fertility. Normal semen is gray white or slightly yellow. If pink or red appears, it is bloody semen. The normal semen volume is 2-6 milliliters, and if it exceeds 7 milliliters, it is considered excessive. Not only will the sperm density decrease, but it is also easy to flow out of the female vagina, resulting in a decrease in the total number of sperm. If the total amount of semen is less than 2 milliliters, it means that the semen volume is low. Less than 1 milliliter is considered too low and can easily lead to infertility. After ejaculation, semen generally turns into liquid within 15-30 minutes. If it cannot change its shape after more than 30 minutes, it is called non liquefaction of semen in clinical practice and is also a cause of infertility.
