Figure 1: Graphic representation of the scoring of the early embryo quality on days 2 and 3 and the association with sperm tACE. Number of tACE molecules per spermatozoon on (a) day 2, and (b) day 3; and percentage of tACE-positive spermatozoa on (c) day 2, and (d) day 3. Box-plot graph shows the median values as lines across the box. Lower and upper box lines indicate the 25th–75th percentile. Whiskers represent the maximum and minimum values. *P < 0.05 and **P < 0.01. tACE: testicular angiotensin-converting enzyme.
