Hello Mr Shekhar, it is unlikely that any medication would help you, as there are good chances of the reversal failure, so even if your testicles ARE producing sperms, they wont be able to pass into your semen, I suggest assisted reproductive techniques, if you are planning for a baby.
Vasectomy is a sterilization procedure, todays date there are scar less surgery available (NSV) after that you can not reverse this. But sexual life is normal but before goes for this you should prepare your mind.
Its not clear what do want out of your question other wise this is ok divert your attention to wards god/guru
if you have faithin nature then start enjoying other thinghs except sex) around you
do some creative work
do yoga exercise.
Please Vasectomy gives psychological weakness For phimosis. Put some coconut oil drops below penile skin and do forward and backward movements of penile skin slowly avoiding masturbation Do it for 3 months It will be free If not relived Consult nearby surgeon in person and go for circumcision if needed.
