How should this medicine be used?
This process usually begins in response to sexual stimulation, such as being touched by your partner or seeing sexual imagery. As more blood flows to the corpora cavernosa, your penis becomes larger and firmer, creating an erection. A fibrous membrane called the tunica albuginea wraps around this tissue, helping you to maintain your erection during sexual intercourse. After you reach orgasm and ejaculate, blood flows out from this tissue and your penis starts to become flaccid once again. A range of issues can cause erectile dysfunction, but many cases of ED are caused by health issues that affect blood flow to your penis.
