According to Ayurveda, semen is the last Dhatu that is formed out of food. Out of food is manufactured chyle. Out of chyle comes blood. Out of blood comes flesh. Out of flesh comes fat. Out of fat comes bone. Out of bone comes marrow. Out of marrow comes semen. These are the Sapta Dhatus or the seven Dhatus that support this life and body. Mark here how precious is semen! It is the last essence. It is the Essence of essences. The Veerya comes out of the very marrow that lies concealed inside the bones.
