<s>[INST] Hi, [/INST] Welcome to HCM!According to WHO study if a person has 15million sperm he is considered to be a normal man earlier it was 20 million. It is good that you have such a high count but motality rate is low.There are so many medicine in homeopathic system of medicines which will increase the sperm count as well as it will increase the motality rate. So consult a good physician.Take care.Dr.Minhas </s>
