Men produce sperm every day. Sperm is produced by the testes, and as long as the testes are functioning properly, a steady stream of sperm is produced every day. Sperm are produced in the testes and take about 10 weeks to reach maturity. Mature sperm are temporarily stored in the epididymis, and during ejaculation the sperm leave the epididymis, pass through the vas deferens, mix with seminal vesicle fluid and prostate fluid, and are discharged from the vas deferens into the urethra and then out of the body. If there is any abnormality of semen, such as azoospermia, necrospermia, high sperm deformity rate, weak spermatozoa, you should go to the hospital in time to improve the semen routine and other related tests, and choose reasonable treatment plan according to the cause.
