Resource summary
GnRH Mechanism
Desensitization
Slow Rise rate looks like continous stimulation
Effect on FSH release
Stimulatary patterns did not change the release of LH/FSH
Due to desensitization to GnRH pulses
Ratio of FSH:GnRH due to
Differential Clearance
Ovarian Feedback
Differential Synthesis in intact tissue
Other hormones that cause FSH secretion
Steroid Feedback Mechanism
Castrated
Males
Effects Testosterone that decreases frequency and amplitude
Females
Increases GnRH receptors but blocked if estrogen or other steroids are given
