Hello Doctor, I am 30 yrs old and detected with azoospermia, I do not know the root cause yet, however, i never had any problem with intercourse, erection and ejaculation. I have strong sexdrive, so on the days i do not do sex with my wife I masterbate. I do sometime feel pain in my right ball (testis) after sex or masterbation (may be 2 times a month) from past 2 yrs. I am also hypothyroid taking does of 50 since last year. However, i do not know when thyroid problem started. I am not sure that above information is how much resourcefull but if possible can u suggest me what kind azoospermia i might be having and can it be curable? Also i have semen test only once and As the sample collection was in room at test center and i was not comfertable, so would it a chance that i didnot ejaculate sperm with semen. Also my semen repert says. viscosity high and liquification: incomple.... pls help with suggestions. Thanks Deep
