Males generally have sperm around the age of 12. There are some differences in development for each individual, depending on the circumstances. Males generally start to develop their sex organs around the age of 12 and gradually develop maturity, which may produce sperm. After the development of boys, the secretion of androgen increases, and the secondary sexual characteristics gradually appear, manifested in the gradual enlargement of testicles, the emergence of prominent throat knots, long beard, pubic hair development. If pubertal boys do not show secondary sexual characteristics for a long time, they should go to the hospital in time for examination and treatment. Men start to develop their sex organs around the age of 12, and the secretion of androgen increases, which will produce sperms, which are stored in the seminal vesicles for a long time, and when they are stored to a certain number, they will be discharged from the body, and spermatozoa will occur. This is a normal physiological phenomenon. If a man’s sperm production is too low for a long time, he needs to go to the hospital for examination in time, after clarifying the cause of the disease, and then treat the symptoms under the guidance of the doctor.
