Hello, Welcome to HCM, I am Dr. Das
Look, whatever your doctor says, one thing is clear that you are fertile. The previous pregnancy
is a proof of that.
I think you should take a second opinion
. Now a days, the definition of low sperm has been changed.
So, you should consult with an infertility
specialist with the semen analysis
I think you do not need anything.
Hope, this would become helpful.
