Can We Use Tadalafil Tablets for Erectile Dysfunction?

Erection is achieved by increasing blood flow to the spongy penile tissues, temporarily when you are sexually aroused. The release of nitric oxide (NO) from nerve terminals and endothelial cells of the penis stimulates the synthesis of cyclic guanosine monophosphate (more commonly known as cGMP) in smooth muscle cells. cGMP relaxes smooth muscle and increases blood flow to the corpus cavernosum of the penis which in turn produces Penile erection during sexual stimulation.

Erectile problems are very commonly seen in men worldwide. It can occur due to multiple causes and reasons. Erectile dysfunction can be caused by a range of factors, including underlying health conditions, stress, and anxiety.
