According to Indian notion, this universe follows a cosmic law called Rita. Each one's birth is supposed to reach the supreme goal; meanwhile he must do the duty entrusted to him by his nature i.e., to extend or perpetuate his race. In fact, Indian tradition speaks of a son or progeny as one's own self-reborn -atma vai putra namasi. The marriage was therefore designed to get a progeny and not for mere sensual pleasures. This longing for a progeny is held as one of primary desires of mankind by Upanishads - 'Putraisana'. This paved way for the development of Vajikarana branch of Ayurveda.

The term vaja means both speed and semen. Thus this branch of Ayurveda is designed to promote virility as well as power, the term Vajikarana strictly from grammarian's point of view, means making a man with some defect in his Sexual system to total fitness and to enable him to acquire a healthy progeny. In ancient days or as per Ayurvedic principles, it was a routine procedure to take some aphrodisiac before understanding and indulging in sexual intercourse. The idea underlying this practice was to promote/ensure the quantity and quality of semen along with the enjoyment of sexual bliss.
