 [ Symptoms ] hi i have recently undergone a vasectomy and after 1 sample i was asked to do another after putting my second sample in the urologist has asked to see me face to face in 7 days time im not sure if this is normal and i have worked myself up about this thinking they may have detected something in my sample showing something serious like prostate cancer since the procedure i have had little aches and pains in my left testicle which i assumed was normal and may very well be ive also had a bit of a dull ache in my lower left back which comes and goes i may not even notice this for days should i be worried about them calling me in they have not said its urgent or asked me to take someone in is it normal to be asked to see your urologist after a result [ Disease ] semen analysis is not suitable to diagnose prostate ca azoospermia has to be established before declaring sterility this re testing is most likely a part of that very protocol to detect any viable number that could lead to impregnation though vasectomy is very safe method and only 1  failure rate is there retesting at three weeks is ideal to confirm azoospermia wishing you best of health thanks
