If you want to increase your sperm count, you must protect yourself first. There are many factors why sperm count decreases, so if you want it produce and continue producing healthy sperms, you can either follow any of the following:
Stop smoking because it decreases sperm count since tobacco slows down the sperm movement, consume less alcohol because alcohol produces estrogen which suppresses sperm, don’t use drugs, don’t use lubricant (or if you must, use natural lubricants only) because it interferes with sperm motility, don’t use steroids, stay away from pesticides, lead, mercury and other environmental hazards and toxins, get hydrated daily because dehydration has a negative effect on your sperm count, and drink Vitamin C because it helps increase sperm motility.
