Chi Kung believes that great sex bolsters the immune system, strengthens internal organs, enhances our emotional well-being, and inspires creativity. Considered to be one of the three treasures of life, sexual energy is the foundation for our life-force energy and spiritual awareness. So having adequate sperm count can also help longevity.
"SCROTUM PUMPS COLD SPERM ENERGY UPWARD
The scrotum acts like a pump. The scrotum is tight and cool to the touch during youth and after a refreshing sleep. It is loose in old age or after fatigue. Strong flow of life energy tightens the skin. The scrotum is the factory that produces the sexual energy, sperm and male hormones. So there is a tremendous store of yin chi in this area - cold life force energy. All sexual energy whether male or female is yin in its latent or resting state. Sexual fluids belong to the water element in the chinese system of classifying the qualities of different types of chi. However yin energy can rapidly change its nature and become more yang or hot when sexually aroused. This can only happen if the sperm is already manufactured while the testicles are still cool.
In fact western scientists have determined that male sperm count goes up dramatically when the testicles are put on ice and several companies are already selling special devices like a freeze-pak jock strap to aid infertile men. The cold quality of sperm energy means it must be circulated upward to harmonize with the hot mental energy in the head and the chest area and vice verse."
