Spermatic parameters in control and CYP19A1^−/− rabbits. Motility and morphometric parameters of the sperm from control and CYP19A1^−/− rabbits were obtained by Computer Assisted Sperm Analysis. Percentages of (A) total motility and (B) progressive motility of the sperm were decreased in mutants. Percentages of (C) bent tails and (D) Distal Midpiece Reflex were increased in CYP19A1^−/− semen, together with (E) proximal droplets and (F) distal droplets. Dots represent the average of two successive semen collections per animal. For CYP19A1^−/− rabbits, three sets of two successive ejaculations were collected over a one-year interval. The median is shown in red. Control n = 10; CYP19A1 ^−/− n = 5. Mann–Whitney test: * p-Value < 0.05; ** p-Value < 0.005; *** p-Value < 0.0005.
