Men produce sperm on a daily basis, and sperm are formed from the testes. If a man’s testes are functioning normally, sperm are formed continuously every day. The testes are the exclusive organ that produces sperm. The sperm produced by the testes are primary sperm, which need to be transported to the epididymis for maturation before they can have a normal physiological function, and they need to be stored in the seminal vesicles, where they can be ejaculated when the urge to do so arises. The number of times you can have normal sex varies from person to person, and each person’s needs are different, but regardless of age, you need to have regular sex. Healthy young adults may have sex relatively frequently, and as they age, the number of times they have sex may gradually decrease. If the number of sexual intercourse is too frequent for a long period of time, there will be physical fatigue, labor, weakness and back pain, etc. It is recommended to make adjustments and reduce the number of sexual intercourse to avoid unnecessary harm to the body. If the testicles function abnormally, there will be no sperm production or the quality of sperm produced is not up to standard, which will lead to the failure of women to achieve natural pregnancy. In this case, it is recommended to carry out relevant examinations in a timely manner, and after clarifying the specific causes, you should actively carry out symptomatic treatment.
