Another key point is that it is not recommended to wear corsets. Male testicles must be in a low temperature state in order for sperm to survive and produce normally. Generally, the temperature of testis is one or two degrees lower than normal and normal body temperature. If you wear tights, the scrotum will stick tightly to your body, which is not conducive to heat dissipation. This will lead to a large number of sperm death or mutation in the testis. Will affect the reproductive function in the future, so, especially Lan, I suggest wearing body-shaping clothes, preferably loose clothes, especially underwear, and don't wear too tight and loose micro-shirts.
