Full answer

Erectile dysfunction is common, increases with age, and is frequently an early signal of vascular disease — endothelial dysfunction in the penile vasculature often precedes coronary disease by years. Hormonal contributors include low testosterone, hyperprolactinemia, and thyroid dysfunction. Within oMeds review, ED workup includes total and free testosterone, SHBG, estradiol, prolactin, thyroid status, fasting glucose, A1C, and a lipid panel, alongside symptom and medication history. Pathway design addresses underlying drivers in addition to symptom relief.
