Lipid profiles and ovarian reserve status: a longitudinal study

Area of Science:

• Reproductive Endocrinology
• Cardiovascular Health
• Lipid Metabolism

Background:

• Cardiovascular disease (CVD) risk in women escalates post-menopause.
• The relationship between ovarian reserve and CVD risk is not well-established.
• Ovarian reserve status may influence cardiovascular health during reproductive years.

Purpose of the Study:

• To investigate the association between ovarian reserve status and changes in lipid profiles.
• To explore potential early cardiovascular risks linked to diminished ovarian reserve.

Main Methods:

• A 12-year longitudinal cohort study involving 1015 women aged 20-50.
• Ovarian reserve assessed via age-specific anti-Müllerian hormone (AMH) levels.
• Comparison of cardiovascular risk factors, including lipid profiles, across AMH quartiles.

Main Results:

• While initial lipid profiles and blood pressures were similar, significant changes in total cholesterol (TC), LDL, and HDL over time varied by AMH quartile.
• Incremental changes in TC were observed in the lowest AMH quartile.
• Generalized estimating equation (GEE) analysis revealed time-dependent variations in lipid profiles based on ovarian reserve.

Conclusions:

• Lower ovarian reserve may indicate increased susceptibility to cardiovascular risk factors, specifically lipid disturbances.
• These lipid disturbances can occur even during a woman's reproductive lifespan.
• Further long-term studies are recommended to confirm these findings.
