Testosterone/Estradiol Ratio
The testosterone-to-estradiol ratio reflects the balance between androgen and estrogen activity, largely set by the aromatase enzyme that converts testosterone to estradiol. Low ratios in men can accompany obesity, aging, and alcohol use and may contribute to low libido, erectile dysfunction, and gynecomastia. Weight loss and aromatase-related interventions can improve the ratio.
