Androgen Receptors Expression in Pituitary of Male Viscacha in relation to Growth and Reproductive Cycle

Figure 2

Morphometry of AR-ir cells in pituitary of male viscacha in different pituitary PD zones. (a) % ARc-ir cells. LP-FETUS: dorsal R. versus ventral R., rostral E., and caudal E. Prepubertal: medial R. versus ventral R. and caudal E. Adults: the percentage of ARc-ir cells did not reveal statistically significant changes in PD zones. (b) % ARn-ir cells. Immature: medial R. versus dorsal R. and rostral E. Prepubertal: medial R. versus dorsal R. and ventral R. Adult-Rep. P.: caudal E. versus the other PD zones. Adult-Reg. P.: medial R. versus ventral R. and rostral E. Adult-Rec. P.: caudal E. versus rostral E. and medial R. Fetuses from midpregnancy, MP-FETUS; fetuses from late pregnancy, LP-FETUS; reproductive period, Rep. P.; gonadal regression period, Reg. P.; gonadal recovery period, Rec. P.; region, R.; end, E.
