Human sperm bank sperm collection and provision abide by the voluntary and socially ethical principles of the person concerned, not for profit Human sperm bank is a socially beneficial institution. Sperm donation is a humanitarian act, which is as honorable as blood donation and blood stem cell donation! In China, about 10% of couples have the problem of infertility, which is not a serious disease, but is related to the happiness of families and social stability. While vigorously promoting the family planning policy, China is actively carrying out the treatment of infertility, so that childless couples can obtain a child, thus reducing their psychological and social pressure. Couples who cannot have children due to the husband’s lack of sperm can solve their fertility problems through artificial insemination by sperm donation. Therefore, sperm donation is a humanitarian act and plays an important role in the enjoyment of reproductive health for all. Sperm donor semen is stored in sperm banks, and after passing quarantine, it can be provided to couples who are infertile due to male factors to implement assisted reproduction techniques, and also provides an alternative eugenic method for couples who are consanguineous or have a family history of genetic diseases in the male partner; in addition, the establishment of sperm banks also provides a convenient condition for further research on the physical and chemical properties of semen and sperm function. In addition, as the sexual organs of young men develop, the testes produce sperm, the prostate and seminal vesicles secrete seminal plasma, and the two synthesize semen, the main components of which are water and a small amount of organic components. Under normal circumstances, when semen reaches a certain amount, there is nowhere to accommodate it in the body, which is called “full is overflowing”. There are three main ways to get out of the body, namely seminal emission, masturbation, sexual intercourse, so normal men, 1-3 times a week, the occurrence of seminal emission does not affect the body, on the contrary, a longer period of time without seminal emission, will produce sexual irritability, memory and other discomfort. Whether you are a teenager or a middle-aged or elderly person, moderate masturbation is not only harmless but also beneficial to your physical and mental health and helps to meet your physiological needs. Sperm supply will not affect your health. Regular ejaculation is good for semen metabolism and physical health.
