Kegel exercises or Kegel training are named after their inventor, the American gynecologist Arnold H. Kegel. Namely, it was he who discovered that many of his patients were affected by a sensitive bladder after the birth of a child. Therefore, he attributed this to the fact that pregnancy and childbirth weaken muscles within the pelvis that are not visible from the outside. Instead of treating these symptoms with medication or surgery, as was common at the time, he prescribed pelvic floor training for women later in the 1940s. His patients claimed that the exercises could help them, and their love lives also benefited from it. Even today, Kegel exercises are prescribed to strengthen the muscles of the pelvic floor, not only for women who have recently given birth, but also for those who suffer from a sensitive bladder. These exercises help strengthen the pelvic floor muscles. A Kegel study showed that exercises can help with cystocele, rectocele and urinary stress incontinence. Also, it indicates that urethral sphincters and support systems in women can prevent urinary incontinence and prolapse of external organs.
