Explanation
The aim of Kegel exercises is to improve muscle tone by strengthening the pubococcygeus muscles of the pelvic floor. Kegel is a popular prescribed exercise for pregnant women to prepare the pelvic floor for physiological stresses of the later stages of pregnancy and childbirth. Kegel exercises are said to be good for treating vaginal prolapse and preventing uterine prolapse in women and for treating prostate pain and swelling resulting from benign prostatic hyperplasia (BPH) and prostatitis in men. Kegel exercises may be beneficial in treating urinary incontinence in both men and women. Kegel exercises may also increase sexual gratification and aid in reducing premature ejaculation. The many actions performed by Kegel muscles include holding in urine and avoiding defecation. Reproducing this type of muscle action can strengthen the Kegel muscles. The action of slowing or stopping the flow of urine may be used as a test of correct pelvic floor exercise technique but should not be practiced as a regular exercise to avoid urinary retention.
It is now shown that the components of levator ani (the pelvic diaphragm), namely pubococcygeus, puborectalis and ileococcygeus, contract and relax as one muscle. Hence, pelvic floor exercises involve the entire levator ani rather than pubococcygeus alone. Pelvic floor exercises may be of benefit in cases of fecal incontinence and pelvic organ prolapse conditions e.g. rectal prolapse.

Famous quotes containing the word explanation:
“We live between two worlds; we soar in the atmosphere; we creep upon the soil; we have the aspirations of creators and the propensities of quadrupeds. There can be but one explanation of this fact. We are passing from the animal into a higher form, and the drama of this planet is in its second act.”
—W. Winwood Reade (1838–1875)
“Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.”
—Richard Dawkins (b. 1941)
“How strange a scene is this in which we are such shifting figures, pictures, shadows. The mystery of our existence—I have no faith in any attempted explanation of it. It is all a dark, unfathomed profound.”
—Rutherford Birchard Hayes (1822–1893)
