What is good yoga pose to boost sperm quality? Try Mahamudra. It’s a tantric practice which is easy for both beginners and more advanced yogis. Sit on the floor with right leg out straight in front. Bend the left knee and place the heel of the left foot into the perineum. From the hips bend forward with a straight spine over the extended leg and place hands on the floor either side of the leg (or if you can grab the foot). Breathe through the nose slowly, 6 times, then change sides. The gentle compression of the foot in the groin brings fresh blood and prana to the reproductive organs and helps to improve sperm mobility and motility.
