What Is The Treatment To Increase The Motility Of The Sperms?

Dear Doctor:My name is Ali, age 42, height 5'.5", weight 62 kg. I am suffering from necrospermia for the last two decades. More than 70% of my sperms are dead. Despite having a lot of unani, allopathetic and homeopathic treatment, food supplements containing vitamins etc by the advice of urologists, no positive improvement witnesses so far. The situation is hopelessly bad. I am issuless for more than 10 years. What should I do for bringing motility of sperms at least 50% of total count. My count is 56 million per ml after three days abstinence with 70% dead sperms. Kindly advice for effective treatment and special medicine for necrospermia treatment. Thanks.
