Cardiac myocyte size. Right ventricular (RV) dimensions were greater than left ventricular (LV) dimensions for mononucleate length (A), mononucleate width (B), binucleate length (C), and binucleate width (D) in fetal sheep at ~135 days of gestation (dGA) after maternal exposure to vehicle (control: n = 8 female fetuses and 4 male fetuses) or testosterone propionate from 30 to 59 dGA (early T; n = 4 female fetuses and 5 male fetuses) or from 60 to 90 dGA (late T; n = female fetuses and 5 male fetuses). Values are means ± SE. Comparisons were performed by three-way mixed-model ANOVA. ‡Different from the RV (P < 0.05, exact values in text).
