Anastrozole / Exemestane (Aromatase Inhibitors) vs Testosterone (TRT)
Both are used for sexual health. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Anastrozole / Exemestane (Aromatase Inhibitors) | Testosterone (TRT) | |
|---|---|---|
| Human evidence | ★★★★☆ | ★★★★★ |
| Legal status | Prescription, Off-Label | Controlled, Prescription |
| How it works | Inhibit aromatase (CYP19A1), the enzyme converting testosterone to estradiol. Anastrozole is reversible; exemestane is a suicide (irreversible) inhibitor. | Binds the cytoplasmic androgen receptor (AR); the hormone-receptor complex translocates to the nucleus and binds androgen response elements (AREs) on DNA, switching on genes for muscle protein synthesis, erythropoiesis, and bone density.… |
| In plain English | High testosterone partly converts to estrogen, which can cause bloating and gyno. These drugs block that conversion. Easy to overdo — crashing estrogen wrecks mood, joints, and libido. | Testosterone slots into a docking station (the androgen receptor) inside your cells, which then walks to the cell's DNA and switches on the "build muscle, make blood, strengthen bone" genes. TRT restores a normal level in men who are… |
| Bottom line | Use only if estradiol is genuinely high; low estrogen is as bad as high. | Transformative for confirmed low-T; a different risk equation for enhancement in normal men. |
| Availability | Prescription only | Controlled substance |
Which is better for sexual health?
Testosterone (TRT) has the stronger human-evidence rating (★★★★★ vs ★★★★☆), but the right choice still depends on your goal, tolerance and budget.
