Hello dear I understand your concern Your sperm count is 4-5 million. It is very low. Natural pregnancy is not possible. I would suggest to consult urologist and undergo routine blood test, serum testosterone and USG scan of pelvis to rule out problem Drugs like clomiphen citrate can be used to increase sperm count Take multivitamin tablet Do regular exercise, eat healthy diet with lots of fruit and green leafy vegetables, drink plenty of water Avoid: stress, alcohol, smoking, fatty/oily food Last option is in vitro fertilization, intrauterine insemination Hope this may help you Contact further if follow up needed Best regards Dr. Sagar
