Hello,
There are very few chances to cure azoospermia in any form of medicine. However, Ayurveda does have treatment approach that may work. Seek out a combo of Kavach beej, aswagandha, etc . Search for an indian store and you are likely to find the pills. In india, they are available by the brand names of Adyzoa, Semento, Spemen forte. You should use the drug for atleast 3 months.
(This is "CUT and PASTE")
Good luck
