Kegel exercise, also known as pelvic floor exercise, involves repeatedly contracting and relaxing the muscles that form part of the pelvic floor, now sometimes colloquially referred to as the "Kegel muscles". The exercise can be performed many times a day, for several minutes at a time but takes one to three months to begin to have an effect.{{cite web | title = Pelvic floor muscle training exercises | publisher = MedlinePlus | date = 10 October 2018 | url = https://medlineplus.gov/ency/article/003975.htm | access-date = 14 May 2020 | archive-date = 28 July 2016 | archive-url = https://web.archive.org/web/20160728014759/https://medlineplus.gov/ency/article/003975.htm | url-status = live }}

Mechanism of action

Kegel exercises aim to improve muscle tone by strengthening the pubococcygeus muscles of the pelvic floor. Kegel is a popular{{quantify|date=September 2020}} prescribed exercise for pregnant women to prepare the pelvic floor for physiological stresses of the later stages of pregnancy and childbirth. Various advisors recommend Kegel exercises for treating vaginal prolapse{{cite web|url= http://www.emedicinehealth.com/vaginal_prolapse/article_em.htm|title= Vaginal Prolapse|author= September 2, 2011|date= 2011-02-09|publisher= eMedicineHealth|access-date= 2011-09-02|archive-date= 2006-07-21|archive-url= https://web.archive.org/web/20060721174112/http://www.emedicinehealth.com/vaginal_prolapse/article_em.htm|url-status= live}} and preventing uterine prolapse{{cite web|url= https://www.nlm.nih.gov/medlineplus/ency/article/001508.htm#Prevention|title= MedlinePlus Medical Encyclopedia: Uterine prolapse|date= 2011-08-29|publisher= Nlm.nih.gov|access-date= 2011-09-02|archive-date= 2001-08-20|archive-url= https://web.archive.org/web/20010820053741/https://www.nlm.nih.gov/medlineplus/ency/article/001508.htm#Prevention|url-status= live}} in women and for treating prostate pain{{citation needed|date=August 2019}} and swelling resulting from benign prostatic hyperplasia (BPH) and prostatitis in men. Kegel exercises may have benefits in treating urinary incontinence in both men and women.{{cite web|url= https://www.nlm.nih.gov/medlineplus/ency/article/003975.htm|title= MedlinePlus Medical Encyclopedia: Kegel exercises|date= 2011-08-29|publisher= Nlm.nih.gov|access-date= 2011-09-02|archive-date= 2001-06-17|archive-url= https://web.archive.org/web/20010617161228/https://www.nlm.nih.gov/medlineplus/ency/article/003975.htm|url-status= live}} Kegel exercises may also increase sexual gratification, allowing women to complete pompoir and aiding men 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 the correct pelvic-floor exercise technique.Kenway, M., and Goh, J. (2009).

The components of levator ani (the pelvic diaphragm), namely pubococcygeus, puborectalis and iliococcygeus, contract and relax as one muscle.{{cite book |last1=Gowda |first1=Supreeth N. |last2=Bordoni |first2=Bruno |title=StatPearls |date=2022 |publisher=StatPearls Publishing |url=https://www.ncbi.nlm.nih.gov/books/NBK556078/ |access-date=11 May 2022 |chapter=Anatomy, Abdomen and Pelvis, Levator Ani Muscle |pmid=32310538 |archive-date=9 November 2022 |archive-url=https://web.archive.org/web/20221109014229/https://www.ncbi.nlm.nih.gov/books/NBK556078/ |url-status=live }} Hence pelvic-floor exercises involve the entire levator ani rather than pubococcygeus alone. Pelvic floor exercises may help in cases of fecal incontinence and in pelvic organ prolapse conditions e.g. rectal prolapse.{{cite journal|last= Bø|first= K|year= 2006|title= Can pelvic floor muscle training prevent and treat pelvic organ prolapse?|journal= Acta Obstet Gynecol Scand|volume= 85|issue= 3|pages= 263–8|doi= 10.1080/00016340500486800|pmid= 16553172|s2cid= 221452341|doi-access= free}}

Kegel exercises can train the perineal muscles by increasing the oxygen supply and the strength of those muscles.{{Cite journal|last1=Puppo |first1=Vincenzo|last2=Puppo|first2=Giulia|date=January 2016 |title=Comprehensive review of the anatomy and physiology of male ejaculation: Premature ejaculation is not a disease: Anatomy and Physiology of Ejaculation |journal=Clinical Anatomy |volume=29|issue=1|pages=111–119|doi=10.1002/ca.22655|pmid=26457680|s2cid=9213013}} The names of the perineal muscles are: ischiocavernosus (erection), bulbocavernosus (ejaculation), external sphincter of the anus, striated urethral sphincter, transverse perineal, levator of the prostate, and puborectalis.{{cite journal |last1=Woodley |first1=SJ |last2=Lawrenson |first2=P |last3=Boyle |first3=R |last4=Cody |first4=JD |last5=Mørkved |first5=S |last6=Kernohan |first6=A |last7=Hay-Smith |first7=EJC |title=Pelvic floor muscle training for preventing and treating urinary and fecal incontinence in antenatal and postnatal women. |journal=The Cochrane Database of Systematic Reviews |date=6 May 2020 |volume=5 |issue=3 |pages=CD007471 |doi=10.1002/14651858.CD007471.pub4 |pmid=32378735|pmc=7203602 }}

Premature ejaculation is defined as when male ejaculation occurs after less than one minute of penetration.{{Cite book |editor1-last=Goldstein |editor1-first=Sam |editor2-last=Naglieri |editor2-first=Jack A. |title=Encyclopedia of child behavior and development |date=2011|publisher=Springer |isbn=9780387790619 |location=[New York]|oclc=704395400}} The perineal muscles are involved in ejaculation when they are involuntarily contracted. The ischiocavernosus muscle is responsible for male erection, and the bulbocavernosus muscle is responsible for ejaculation. By actively contracting the perineal muscles with Kegel exercises regularly, strength and control of these muscles increase, possibly aiding in the avoidance of premature ejaculation.{{Cite journal |last1=Puppo |first1=V. |last2=Abdulcadir |first2=J. |last3=Mannucci |first3=A. |last4=Catania |first4=L. |last5=Abdulcadir |first5=D. |date=April 2008 |title=T09-P-13 The importance of the Kegel exercises for the erection of the male and female erectile organs (male and female penis) |journal=Sexologies |volume=17 |pages=S136 |doi=10.1016/s1158-1360(08)72894-9 |issn=1158-1360}}

In pregnant women, antenatal PFMT probably helps prevent urinary continence during pregnancy and up to six months after giving birth but for pregnant women who already have incontinence, it is not clear if antenatal PFMT helps to reduce symptoms.

=Fecal incontinence=

In pregnancy, it is not yet clear if antenatal PFMT helps to prevent or treat fecal incontinence.

Pelvic toning devices

Some devices, marketed to women, are for exercising the pelvic floor muscles and to improve the muscle tone of the pubococcygeal or vaginal muscle.

As of 2013, there was no evidence that doing pelvic floor exercise with weights worked better than doing Kegel exercises without weights; there is greater risk with weights, because a foreign object is introduced into the vagina.{{cite journal|last1=Herbison|first1=GP|last2=Dean|first2=N|title=Weighted vaginal cones for urinary incontinence|journal=The Cochrane Database of Systematic Reviews|date=8 July 2013|volume=2013 |issue=7|pages=CD002114|pmid=23836411|doi=10.1002/14651858.CD002114.pub2|pmc=7086390}}

During the latter part of the 20th century, a number of medical and pseudo-medical devices were marketed to consumers as improving sexual performance or orgasms, increasing "energy", "balancing hormones", and as having other health or lifestyle benefits. There is no evidence for any of these claims, and many of them are pseudoscience.{{cite news |last1=Tuteur |first1=Amy |title=Vaginal weight lifting |url=http://www.skepticalob.com/2008/12/vaginal-weight-lifting.html |work=The Skeptical OB |date=18 December 2008 |access-date=1 June 2018 |archive-date=8 November 2022 |archive-url=https://web.archive.org/web/20221108120622/http://www.skepticalob.com/2008/12/vaginal-weight-lifting.html |url-status=live }}{{cite news|title=No, Gwyneth Paltrow, women should not put jade eggs in their vaginas, gynecologist says|url=https://www.washingtonpost.com/news/to-your-health/wp/2017/01/22/no-gwyneth-paltrow-women-should-not-put-jade-eggs-in-their-vaginas-gynecologist-says/|access-date=6 February 2017|newspaper=Washington Post|archive-date=12 February 2021|archive-url=https://web.archive.org/web/20210212191255/https://www.washingtonpost.com/news/to-your-health/wp/2017/01/22/no-gwyneth-paltrow-women-should-not-put-jade-eggs-in-their-vaginas-gynecologist-says/|url-status=live}}
