This treats men with erectile dysfunction (also called sexual impotence). Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE-5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works. By controlling the enzyme, sildenafil helps to form and maintain an erection.
Tadalafil is a proven ED medication and its effects are cumulative and improve with daily use. It’s effective for both male and females. Tadalafil orally can be effective to increase sexual desire, sexual arousal, sexual orgasm and sexual satisfaction. It not only increases nitric oxide in the corpus cavernosum of men, but in women it also results in the relaxation of clitoral and vaginal smooth muscle and increased blood flow in these sites, a normal step in arousal and necessary to achieve orgasm.
While Oxytocin certainly lives up to its reputation as the “Love Hormone,” it also has broader applications like weight management and a performance enhancer. Oxytocin levels reach extreme levels during childbirth and breastfeeding. But they have been found to be elevated during sexual arousal, skin-to-skin contact and orgasm. Due to this, research has been conducted and shown that exogenous administration of Oxytocin can improve libido, orgasm intensity/frequency and sexual pleasure.
