Shenshu (BL23) and Bladder 47 are combined known as the Sea of Vitality points that are located on the lower back, between the second and the third lumbar vertebrae, two finger widths away from the spine at the level of the waist. These are extremely beneficial points of acupressure and acupuncture for infertility that helps in treating impotency, premature ejaculation, sexual reproductive problems, fatigue and lower-back pain. These points are also useful for strengthening the immune system and boosting energy flow. These points can be stimulated by applying pressure on the points using the back of your hands. Rub the points up and down for 1 minute in order to create heat and friction. Then firmly press the points using the thumb and fingertips for at least another minute.
