Tadalis SX 20 mg can help improve erection strength, but it works in a specific way. Here’s a detailed explanation: How Tadalis SX 20 mg Works Active ingredient: Tadalafil, a PDE5 inhibitor. Mechanism: It relaxes smooth muscles and dilates blood vessels in the penis. This increases blood flow to the corpora cavernosa during sexual stimulation, helping the penis become firm and maintain an erection. Sexual stimulation is required; Tadalis SX does not cause spontaneous erections. Effects on Erection Strength Improved rigidity: More blood enters the penile tissue, resulting in a firmer and stronger erection. Longer duration: Tadalis SX 20 mg effects can last up to 36 hours, giving more flexibility in timing sexual activity. Better confidence: Men often report feeling less anxious about performance, which can indirectly improve erection quality. Limitations Tadalis SX does not increase sexual desire (libido). It does not cure the underlying causes of erectile dysfunction, such as hormonal issues or severe vascular disease. Effectiveness may vary depending on age, overall health, and underlying conditions like diabetes or heart disease.
