The recovery time after a male ejaculation needs to be determined according to the age and physical condition of the male, and cannot be generalized. The male body around puberty is more androgenic and has better physical strength, so the rest time after ejaculation is shorter and the recovery is faster for boys of this age. Generally one or two hours is enough, and after each ejaculation, the impact on the body is relatively small. As men grow older, after they are over 40 years old, their physical strength will gradually decline and their rest time will gradually lengthen, reaching the age of fifty after which the rest time for individual men may reach 24 hours. Although younger men recover more quickly, they still need moderation. If ejaculation is too frequent, it may cause symptoms such as weakness in the waist and knees and weakness in the limbs, which can lead to deficiency of kidney essence and deficiency of kidney yang, which is not good for the health of the boys.
