Hi Your doctor has rightly asked for HSG test. As she had surgery for adhesions around the tube, it is important to confirm that tubes are functioning normally. Your sperm count is normal. What about the other parameters of semen test? Yes If tubes are not functioning normally you need to go for test tube baby treatment. IF I were your doctor I would also advise you to have laparoscopic surgery for varicocele. With varicocele the local temperature in the scrotum increases affecting the sperms. Ask your wife to take one tablet of folic acid daily. To increase your chances of conception maintain you both should maintain normal BMI, quit smoking ( if smoking) and have intercourse at least three times in a week. If you have any further concerns do contact me through Healthcare Magic.
