Module 9
Pathophysiology of PCOS: Hyperandrogenism
1
GnRH Pulsatility, LH, and Ovarian Androgen Production
Describe the role of abnormal GnRH pulsatility and excessive LH stimulation in ovarian androgen production.
2
Thecal Cell Dysfunction in PCOS Hyperandrogenism
Explain the intrinsic dysregulation in theca cells that contributes to hyperandrogenism in PCOS.
3
Insulin's Role in Ovarian Androgen Production
Explain how insulin resistance and hyperinsulinemia synergistically enhance ovarian androgen production.
4
Adrenal Androgen Excess in PCOS
Describe the contribution of adrenal androgen excess in a subset of women with PCOS.
5
PCOS: Unraveling SHBG and Free Androgen Dynamics
Explain the mechanisms leading to reduced SHBG levels and an increased free androgen index in PCOS.
6
Androgen's Impact on Hair and Sebaceous Glands
Describe how androgens affect target tissues like the hair follicle and sebaceous gland to cause clinical signs.
