Fig. 3From: Effect of Letrozole on sperm parameters, chromatin status and ROS level in idiopathic Oligo/Astheno/TeratozoospermiaComparison of flow cytometry analysis of TUNEL positive% spermatozoa obtained from iOAT men with T:E2 ratio ≤ 10, before and after letrozole treatment. a) Dot plot of spermatozoa. The cells gated in R1 region were analyzed; debris was excluded from the analysis. b) Pre-treatment TUNEL positivity% in test semen sample referenced to one of a negative control semen sample, c) Post-treatment TUNEL positivity% in semen sample referenced to one of a negative control semen sampleBack to article page
