The components of seminal plasma in semen are mainly proteins and various enzymes, as well as inorganic and organic salts containing various chemical elements. These substances can be continuously supplemented by daily food. As long as the nutrition is normal and the body functions normally, they will not be lacking.
A normal man discharges only 3-5 milliliters of semen each time, of which seminal plasma accounts for more than 90%. The secretion and supplementation of seminal plasma are very rapid, but the production of sperm takes a long time (the cycle is about 74 days).
Clinical studies have shown that during continuous ejaculation, only the first 1-2 times of semen contains more sperm, while the latter decreases or even does not, that is, only excretes the secretion of prostate fluid and bulbar glands. It does not contain sperm.
If more consecutive ejaculations occur, it is often the pleasure generated by the contraction of the ejaculatory tube, without the elimination of semen. This is a self regulating function of the human body, as well as a self protective function.
It has been observed that as long as normal men are healthy and have regular diet and rest, they can generally replenish their semen to the normal range within 1-2 days after a single ejaculation.
It is precisely in view of this regularity of supplementation that clinicians often instruct patients undergoing semen analysis to prohibit ejaculation within 3-5 days when sampling semen samples, in order to maintain semen at a normal level and ensure accurate examination results.
Judging from the above, semen does not dry up and normal semen excretion does not result in kidney deficiency. However, it must be pointed out that no one can violate their own laws of physiological activity, and excessive indulgence can harm the body.
