And now for something completely different. Why? Because it's night shift.
"According to Yogic science, semen exists in a subtle form throughout the whole body. It is found in a subtle state in all the cells of the body. It is withdrawn and elaborated into a gross form in the sexual organ under the influence of the sexual will and sexual excitement. An Oordhvareta Yogi (one who has stored up the seminal energy in the brain after sublimating the same into spiritual energy) not only converts the semen into Ojas, but checks through his Yogic power, through purity in thought, word and deed, the very formation of semen by the secretory cells or testes or seeds. This is a great secret." - Sri Swami Sivananda, Brahmacharya (Celibacy)
