Penisole is a dietary supplement marketed for male genital enhancement. The product contains a blend of plant extracts that are claimed to promote tissue growth. The proposed therapeutic role is to increase penile size and improve sexual confidence. Pharmacologically the ingredients are believed to enhance nitric oxide production in endothelial cells. Increased nitric oxide leads to smooth muscle relaxation and greater blood flow to the organ. The resulting vasodilation may cause temporary swelling and a perception of increased length. Some components are thought to modulate androgenic pathways that influence penile tissue development. Overall the mechanism relies on circulatory and hormonal signaling rather than direct tissue regeneration.

Penisole is a herbal supplement marketed for male enhancement. Its pharmacological properties arise from plant extracts that influence hormonal pathways. The formulation is thought to encourage the body to increase testosterone production in the testes. Higher testosterone levels can improve libido and contribute to erectile function. The mechanism of action involves modulating endocrine signals and promoting endothelial relaxation. Enhanced blood flow to penile tissue may support the ability to achieve an erection. Overall research indicates that these effects are indirect and can vary between individuals.
