Role of androgens in normal and pathological ovarian function

Area of Science:

• Endocrinology
• Reproductive Biology
• Molecular Endocrinology

Background:

• Androgens exert effects through the androgen receptor (AR), a nuclear receptor crucial for male reproduction.
• The role of AR in female reproduction is increasingly recognized, impacting ovarian function and fertility.
• Distinguishing AR actions from estrogenic effects has been challenging in pharmacological studies.

Purpose of the Study:

• To review and synthesize evidence on the role of AR-mediated actions in normal and pathological ovarian function.
• To elucidate the mechanisms by which AR regulates ovarian health, follicle development, and ovulation.
• To explore the involvement of AR in polycystic ovary syndrome (PCOS) and female fertility.

Main Methods:

• Analysis of global and cell-specific female Ar knockout mouse models.
• Review of observational studies in humans.
• Integration of findings from pharmacological studies and animal models.

Main Results:

• AR signaling is essential for maintaining ovarian function and female fertility.
• AR plays a role in regulating follicle health, development, and ovulation.
• AR-mediated effects are implicated in the pathophysiology of PCOS.

Conclusions:

• AR signaling is a critical regulator of female reproductive health.
• Understanding AR actions provides insights into PCOS and female fertility.
• Further research on AR pathways can inform therapeutic strategies for reproductive disorders.
