Rectal suppositories deliver medication through the highly vascular rectal mucosa, partially bypassing first‑pass liver metabolism so some drugs (such as anti‑inflammatories) can reach effective levels within 30–60 minutes while targeting pelvic tissues with fewer stomach side effects than oral pills. Here’s when they’re clinically useful for men (constipation, hemorrhoids, pelvic/prostate pain, even certain erectile treatments) ...

Bioidentical hormone replacement therapy for men: Science, safety, and real-world results

Most prescription testosterone replacement used in men is already “bioidentical” — the hormone molecule is chemically identical to what the testes produce, even as levels commonly decline about 1% per year after age 30–40.
