(A) FSHb steady state response calculated with Eqs. 1–6 (dashed) and with the direct stimulatory influence of G removed (solid) by replacing G in G (k2 + G) with the fixed values 0.1, 0.5, or 0.9 in Eq. 2. (B) When the stimulatory influence of G is removed, the rise in FSHb leading up to proestrus and the decline following proestrus are very shallow.
