Urogenital Hiatus

What is Urogenital Hiatus?

Technically the Genital Hiatus is defined as the distance, front-to-back, between your urethral opening (where our urine comes out) and the back wall of your vagina.

The genital hiatus is a space but it is used to describe the muscles that form the pelvic floor, together with the organs contained within the area such as the urethra, vagina and rectum.

Genital Hiatus Widening = Sagging Pelvic Floor

The average length of the genital hiatus in women before they have a baby is approximately 3 cm (1.5 inches). However as we age, after childbirth, weight gain, smoking and all those other things that happen to us in life, it can increase in size from between 3-5 cm. This represents the 'sag' of muscular tissue of the pelvic floor.

Genital Hiatus Size

An Increase in size, or widening of the genital hiatus is basically the sagging of your pelvic floor muscles due to ageing, birth, excess weight, smoking and menopause.

If you find that your genital hiatus size has increased or widened, then now is the time to start a regimen of pelvic floor exercises to strengthen the pelvic floor muscles.

  • A wide genital hiatus is improved immensely by performing kegel exercises - Kegel8 could really help!
