Estradiol correlates with erectile dysfunction and its severity in type 2 diabetic patients

Area of Science:

• Endocrinology
• Urology
• Diabetology

Background:

• Erectile dysfunction (ED) is a common complication in type 2 diabetes mellitus (T2DM).
• Hormonal imbalances, including hyperestrogenism, frequently occur in T2DM patients.
• The relationship between estrogen levels and ED in this population requires further investigation.

Purpose of the Study:

• To explore the association between estradiol (E2) levels and erectile function in men with T2DM.
• To determine if elevated E2 is a risk factor for ED severity in diabetic individuals.

Main Methods:

• Retrospective analysis of 57 T2DM patients with ED.
• Assessment of ED using the International Index of Erectile Function (IIEF-5) and penile color-doppler ultrasound (PCDU).
• Hormonal and metabolic profiling including estradiol (E2), total testosterone (T), HbA1c, and lipid profile.

Main Results:

• Estradiol (E2) showed a significant negative correlation with erectile function (IIEF-5 score).
• Patients in the highest E2 quartile had a higher probability of severe ED (61.5%).
• Penile Doppler ultrasound indicated impaired arterial flow (longer Acceleration Time) in patients with higher E2 levels.

Conclusions:

• Elevated estradiol (E2) levels are associated with worse erectile function and reduced cavernous arterial flow in diabetic men.
• Diabetic patients with high E2 are more susceptible to severe ED.
• Estradiol measurement should be considered in the hormonal evaluation of ED in T2DM patients.
