What Is The Urethral Sphincter?

MIAMI, WEST PALM, FORT LAUDERDALE AND DEERFIELD BEACH, FLORIDA – The vagina is made up of different muscles and tissues. It is important for a woman to understand what is going on down there.
The urethral sphincter consists of two muscles that can control the flow of urine through the urethra. These two muscles are called the external and internal urethral sphincter. When you contract these two muscles, your urethra is sealed shut.
The contracting of the external and internal urethral sphincter is also known as the Kegel exercise. Many gynecologists recommend you do these exercises to help tighten the vaginal walls during and after pregnancy.
Cosmetic gynecology surgeon Dr. Mark Scheinberg explains the two urethral sphincter muscles in depth.
External Sphincter Muscle
Located around the back, base of the bladder, and is made up of skeletal muscle. This makes it under voluntary control of the somatic nervous system.
The external sphincter muscle is also made up of three different parts, the sphincter urethra, urethrovaginal sphincter muscle and the compressor urethrae muscle.
Internal Sphincter Muscle
Located near the base of the bladder and adjacent to the urethra, the internal sphincter muscle is a continuation of the detrusor muscle. This is under involuntary control, and is the primary muscle that can restrict the flow of urine.
“Despite what many people may say, males do not have a stronger urethral muscle,” says Dr. Scheinberg, a labioplasty expert. “There is also not any difference between the amounts of urine each sex can hold in their bladder.”
As a woman, you need to urinate more because your bladder shares space with the uterus, which is why childbirth can wreak havoc on your bladder and the supporting tissues of the vagina.
Near the end of labor, the baby’s body will descend through the birth canal. When you reach the point of being 10 centimeters dilated, it’s time to push. The supporting tissues around the vagina can separate and weaken.
A weakened pelvic floor and surrounding muscles could cause the bladder to descend. Surgery to take up the bladder may be an option to correct this. Vaginal reconstruction surgery can tighten the vaginal walls and restore the natural shape.
If you are suffering from vaginal looseness due to childbirth, it can result in a lack of sensation during sex and lowered gratification.
Knowing your body inside and out can result in a better sex life for you and your partner.
