Module 2
Regulation of the Gonadotropic Axis
1
FSH and LH Receptors: Structure and Signaling Pathways
Describe the structure of FSH and LH receptors and their primary G-protein coupled signaling pathways.
2
Gonadal Steroids and GnRH/Gonadotropin Suppression
Explain the negative feedback mechanism where gonadal steroids suppress GnRH and gonadotropin secretion.
3
Estrogen's Role in the LH Surge
Explain the positive feedback mechanism where high estrogen levels trigger the pre-ovulatory LH surge.
4
Inhibin and Activin: Regulating FSH Secretion
Describe the roles of inhibin and activin in the selective feedback regulation of FSH secretion.
5
Receptor Desensitization: Modulating Gonadotropin Responsiveness
Explain receptor desensitization as a local mechanism for modulating target cell responsiveness to gonadotropins.
