LH, T, and FSH levels in WT and GalNAc-4-ST1^–/– male mice. Serum was collected from 8- to 10-week-old male WT and GalNAc-4-ST1^–/– mice. Levels of LH, T, and FSH were determined by radioimmunoassay. In each case, the difference in mean values was significant. (A) P = 0.0001, LH (squares, triangles); P = 0.04, T (inverted triangles, diamonds). (B) P = 0.026, FSH. (C) P = 0.009, LH 5 days following castration.
