Figure 1 The alternative compensatory pathway induced by <italic toggle='yes'>cyp17a1</italic> depletion is <italic toggle='yes'>ar</italic>-independent.

(A–D) Anatomical examination of the testes from control males, ar-/- males, cyp17a1-/- fish, and cyp17a1-/-;ar-/- fish at 6 months post-fertilization (mpf). Black and green arrows indicate the normal and impaired testis in control males and ar-/- males, respectively, whereas the red arrows indicate the hypertrophic testis in the cyp17a1-/- fish and cyp17a1-/-;ar-/- fish. (E) Gridpoint Statistical Interpolation (GSI) from the fish of the four genotypes at 6 mpf. (F–I) Histological analyses of the testes from control males, ar-/- males, cyp17a1-/- fish, and cyp17a1-/-;ar-/- fish at 6 mpf. Black and green letters of spermatozoa (SZ) indicate the normal and decreased number of SZ in control males and ar-/- males, respectively, whereas the red letters of SZ indicate the increased number of SZ in the cyp17a1-/- fish and cyp17a1-/-;ar-/- fish. (J) Statistical analysis of the SZ number in each lumen of seminiferous tubules from the fish of the four genotypes at 6 mpf. The letters in the bar charts (E) and (J) represent significant differences. SC: spermatocytes; SG: spermatogonia.
