Polycystic ovary syndrome (PCOS) causes endometrial progesterone resistance, increasing risks of uterine hyperplasia and cancer. Understanding progesterone receptor (PR) pathways is key to developing effective treatments for women with PCOS.
Area of Science:
- Reproductive Endocrinology
- Gynecologic Oncology
Background:
- Polycystic ovary syndrome (PCOS) is characterized by hormonal imbalances, including altered steroid hormone activity.
- Chronic estrogen exposure and progesterone deficiency in PCOS can lead to endometrial hyperplasia and carcinoma.
- Progesterone receptor (PR) signaling is crucial for normal uterine function.
Purpose of the Study:
- To review endometrial progesterone resistance in women with PCOS.
- To detail PR structure, isoforms, and endometrial expression.
- To discuss PR regulation, signaling in PCOS, and clinical treatments for associated endometrial pathologies.
Main Methods:
- Literature review of human studies on PCOS and endometrial function.
- Analysis of PR structure, isoforms, and expression patterns.
- Synthesis of data on PR signaling pathways and clinical treatment strategies.
Main Results:
- Human studies suggest PR-mediated nuclear signaling pathways are linked to progesterone resistance in PCOS.
- PR structure and isoforms play a role in differential signaling.
- Dysregulation of PR and its signaling contribute to endometrial abnormalities in PCOS.
Conclusions:
- Endometrial progesterone resistance is a significant issue in PCOS.
- Further understanding of PR regulation and signaling is needed for targeted therapies.
- Effective management of endometrial hyperplasia and carcinoma in PCOS requires addressing progesterone resistance.

Disorders of the Female Reproductive System
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
Ovarian Cycle
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Oogenesis
Proliferative Phase
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
