Cenforce 120 increases the level of chemicals like serotonin and norepinephrine in the body. Sildenafil Citrate Tablets Chemicals like serotonin send messages to the nerves, and this is what leads to actions like ejaculation. It is the medicine that helps in solving problems like premature ejaculation. Ejaculation before, during, or shortly after penetration is a disorder in which a man ejaculates before consciously doing so with minimal stimulation. Serotonin increases nerve activity, delays the ejaculatory reflex, thereby improving ejaculation control and increasing ejaculation time. Taking Cenforce 120mg tablets treats erectile dysfunction and prevents premature ejaculation in men aged 18-65. It also provides a remedy for pulmonary arterial hypertension, which increases exercise capacity.
