Male Long-Evans rats at 35 days of age were fed drinking water containing BPA, BPS, EE2 (5 μg/L) or their combinations (BPA+EE2, BPS+EE2, each at 2.5 μg/L) for 14 days. At sacrifice, blood was processed to obtain serum (A). Testicular explants were obtained and incubated in DMEM/Ham’s F-12 culture medium in triplicate without (basal, B) or with 100 ηg/ml ovine LH (NIDDK, NIH) (LH-stimulated, C) for 3 h. Aliquots of serum and spent media were analyzed to measure T concentrations by RIA (n = 6; *p < 0.05).
