A sexual problem, or sexual dysfunction, refers to a problem during any phase of the sexual response cycle that prevents the individual or couple from experiencing satisfaction from the sexual activity. The sexual response cycle has four phases: excitement, plateau, orgasm, and resolution.
It is a prevalent problem, afflicting approximately 40% of women and there are few treatment options.Sexual function results from a complex neurovascular process that is controlled by psychological and hormonal inputs. Like any coordinated physiological response, multiple systems are involved in this function. In respect to proper vaginal and clitoral function, a sufficient blood supply is required.
