Predictive Value of Testicular Volume and Reproductive Hormone Levels for Sperm Existence in Testicular Fine Needle Aspiration in Non-obstructive Azoospermia Patients
Objectives To investigate the predictive value of testicular volume and reproductive hormone levels for sperm existence in testicular fine needle aspiration(TFNA)in non-obstructive azoospermia(NOA)patients.Methods A total of 219 NOA patients underwent fine needle aspiration on the better side of testicles under local anesthesia.According to TFNA results,they were divided into sperm(n=85)and non-sperm(n=134)groups.The age,testicular volume,estradiol(E_2),testosterone(T),luteinizing hormone(LH)and follicle-st...
