The idea that the loss of semen can be detrimental to health is relevant to traditional Indian and Chinese cultures, where it is believed that semen contains vital energy (known as "ojas" in Indian culture and "jing" in Chinese culture). In these cultures, ejaculation is believed to deplete a man's energy and potentially harm his health. This belief is not as prevalent in Iranian or Japanese cultures.
