Serum testosterone (T), FSH and LH levels and testicular T content in untreated normal rats or immunized with TH and adjuvants (E) and injected with saline or L-NAME.

Hormone levels were measured by RIA in sera and testes from untreated normal rats (n = 9) or rats immunized with TH and adjuvants and injected with saline (E+saline, n = 11) or L-NAME (E+L-NAME, n = 12). Data are expressed as mean±SEM.
*p<0.01 versus respective normal and
ΔΔ p<0.05 vs. E+saline.
