AMPK: a master energy regulator for gonadal function.

Area of Science:

• Reproductive Biology
• Cellular Metabolism
• Endocrinology

Background:

• Reproduction is significantly influenced by nutrition and energy metabolism across species.
• Cellular energy sensors, like 5' AMP-activated protein kinase (AMPK), detect energy status (e.g., obesity, diet restriction).
• AMPK is a protein kinase activated by ATP deficiency and molecules like metformin, crucial for treating insulin resistance.

Purpose of the Study:

• To review the primary effects of AMPK in gonadal cells.
• To elucidate AMPK's role in reproductive functions and metabolic regulation within the gonads.
• To discuss AMPK's implications for fertility and infertility treatments.

Main Methods:

• Literature review focusing on AMPK's functions in gonadal cells.
• Analysis of AMPK's involvement in steroidogenesis, cell proliferation, and survival.
• Examination of AMPK's role in oocyte and sperm maturation, germ-somatic cell interactions, and the blood-testis barrier.

Main Results:

• AMPK plays a key role in gonadal steroidogenesis, proliferation, and survival of somatic gonadal cells.
• AMPK influences the maturation of oocytes and spermatozoa.
• AMPK is involved in germ and somatic cell interactions within the cumulus-oocyte complex and the blood-testis barrier.

Conclusions:

• AMPK acts as a crucial interface between metabolism and reproductive function in the gonads.
• Understanding AMPK's role is vital for addressing fertility issues linked to insulin resistance, obesity, and polycystic ovary syndrome.
• Targeting AMPK may offer therapeutic strategies for metabolic-associated infertility.
