Figure 5.
Serum hormone levels are suppressed by treatment with GnRH-ant and return to normal levels when the treatment is stopped. Serum FSH (A), LH (B), and testosterone (C) levels in radiation-only and irradiated monkeys treated with GnRH-ant for 8 weeks are shown. The shaded area represents the period of hormone suppression. Dashed lines indicate minimum levels of detection. The serum hormone levels after irradiation with or without GnRH-ant treatment were compared to the respective values before irradiation, and significant (P<0.001) differences are shown for the values lower ( *) and higher (†) than the pre-irradiation values (Dunnet test).
