The analyses of primary and secondary sex characters and fertility assessment. (A–D) Gross appearance of cyp17a2+/+ male, cyp17a2-/- male, cyp17a2+/+ female, cyp17a2-/- female (n = 10). (E–H) The genital papilla. (I–L) The pectoral fin. (M–P) The anatomical observations. (Q–T) The histological analysis of gonads. Black and green arrow indicates normal and diminished genital papilla, respectively. (U) GSI of cyp17a2+/+ fish and cyp17a2-/- fish at 3 mpf (n > 10). (V) The fertility analysis of cyp17a2-/- males and cyp17a2-/- females mated with WT females and males, respectively (n = 10). (W) The statistical analyses of ovulated eggs of cyp17a2+/+, cyp17a2+/- and cyp17a2-/- females mated with WT males (n = 10). (X) The statistical analyses of fertilization ratio of the ovulated eggs from WT females when mated with cyp17a2+/+ males and cyp17a2-/- males, respectively (n = 10). n.s., no significant difference. *P < 0.05. **P < 0.01. ***P < 0.001.
