I have heard about vaginal rejuvenation in the news. Do I need vaginal rejuvenation at 55?

Seek your gyne. Discuss this with your gynecologist. No one needs elective surgery but many may benefit. There are a variety of associated conditions that relate to overall pelvic laxity and health at age 55 which relate to hormonal alterations and previous birth trauma and chronic strain. These should be discussed first prior to contemplating vaginal rejuvenation.
