Pudendal Nerve: Function, Pain, and Sexual Sensation

It helps a person:

• feeltouch, pressure, pain, and temperature in the genital area;
• control the external urinary and anal sphincters;
• contract some pelvic-floor muscles;
• experience genital stimulation;
• participate in erection, arousal, and orgasm;
• recognize sensations related to urination and bowel movements.

If the nerve is irritated, stretched, injured, or compressed, a person may develop burning pain, numbness, tingling, or discomfort while sitting or having sex.

• pudendal, meaning related to the external genital and perineal region;
• nerve, a structure that carries electrical signals through the body.

It is countable:

• The pudendal nerve supplies sensation to much of the perineum.
• Both pudendal nerves pass through the pelvis.
• The doctor performed a pudendal-nerve block.

Common expressions include:

• pudendal-nerve pain;
• pudendal-nerve compression;
• pudendal-nerve injury;
• pudendal neuralgia;
• pudendal-nerve entrapment;
• preserve pudendal sensation;
• test pudendal function.

It travels through the pelvis and passes near several muscles, ligaments, and bony structures before entering a passage commonly called Alcock’s canal.

Along its route, the nerve may pass close to areas where it can be:

• stretched;
• compressed;
• irritated;
• injured during surgery or childbirth.

Its exact path varies slightly among individuals.

Inferior Rectal Nerve

This branch supplies sensation around the anus and helps control the external anal sphincter.

It contributes to:

• bowel continence;
• awareness of anal sensation;
• muscular control during bowel movements.

Perineal Nerve

The perineal nerve serves skin and muscles in the perineal area.

It contributes to sensation involving parts of the:

• vulva;
• scrotum;
• lower vagina;
• perineal skin.

It also helps control some pelvic-floor muscles.

Dorsal Nerve of the Penis or Clitoris

This sensory branch supplies much of the external sensation of the penis or clitoris.

It plays an important role in:

• touch;
• pressure;
• sexual stimulation;
• genital pleasure;
• orgasmic sensation.

It may transmit sensations involving:

• light touch;
• pressure;
• vibration;
• temperature;
• pain;
• genital stimulation;
• anal and perineal contact.

The nerve is especially important for external genital sensation.

Internal pelvic organs also receive signals from autonomic and other pelvic nerves, so genital and pelvic sensation does not depend on the pudendal nerve alone.

These include muscles involved in:

• closing the external urinary sphincter;
• closing the external anal sphincter;
• supporting the pelvic floor;
• ejaculation;
• rhythmic orgasmic contractions;
• maintaining continence.

The nerve works with autonomic nerves, pelvic-floor muscles, and the brain to coordinate these functions.

Its branches carry stimulation from the:

• clitoris;
• penis;
• vulva;
• scrotum;
• perineum;
• anal region.

It may contribute to:

• genital sensitivity;
• awareness of arousal;
• pleasurable touch;
• pelvic-floor contractions;
• ejaculation;
• orgasm.

However, erection and lubrication depend mainly on autonomic nerve pathways and blood flow. The pudendal nerve contributes sensation and muscular coordination rather than controlling the entire sexual response by itself.

Possible symptoms include:

• burning pelvic or genital pain;
• electric-shock sensations;
• tingling;
• numbness;
• pain while sitting;
• pain during or after sex;
• pain after ejaculation;
• rectal discomfort;
• urinary urgency;
• a sensation of pressure or a foreign object in the pelvis.

Symptoms may occur on one side or both sides.

Pain often improves when standing or lying down, although this pattern is not universal.

Possible causes or contributing factors include:

• prolonged cycling;
• long periods of sitting;
• pelvic trauma;
• childbirth;
• scar tissue;
• surgery;
• repetitive strain;
• pelvic-floor muscle tension;
• pressure from nearby structures.

Not every case of pudendal neuralgia is caused by entrapment. Inflammation, stretching, nerve disease, or an unknown cause may also produce symptoms.

Possible contributing factors include:

• prolonged labor;
• fetal pressure;
• assisted delivery;
• significant pelvic-floor stretching;
• tissue swelling.

Temporary effects may include:

• reduced genital sensation;
• urinary leakage;
• bowel-control difficulty;
• pelvic pain;
• weakness of pelvic-floor muscles.

Many people recover gradually, but persistent symptoms should be evaluated.

• pelvis;
• rectum;
• prostate;
• vagina;
• vulva;
• pelvic floor;
• urinary tract.

Possible effects include:

• numbness;
• pain;
• altered genital sensation;
• continence problems;
• changes in orgasm or ejaculation.

Nerve-preserving techniques may reduce risk when anatomy and medical circumstances allow.

• a detailed symptom history;
• pelvic and neurological examination;
• testing genital and perineal sensation;
• pelvic-floor assessment;
• imaging to exclude other causes;
• diagnostic nerve block;
• evaluation of bladder or bowel symptoms.

There is no single test that confirms every pudendal-nerve disorder.

Conditions that may produce similar symptoms include:

• pelvic-floor muscle spasm;
• urinary or genital infection;
• spinal nerve problems;
• vulvodynia;
• prostatitis;
• endometriosis;
• skin disorders;
• joint or hip conditions.

It may be used to:

• reduce pain;
• support diagnosis;
• provide anesthesia during childbirth;
• assist certain pelvic or anorectal procedures.

Temporary numbness may affect the genitals, perineum, or anus.

Possible risks include bleeding, infection, temporary weakness, or incomplete pain relief.

Possible options include:

• reducing activities that increase pressure;
• changing sitting posture;
• using a pressure-relieving cushion;
• pelvic-floor physical therapy;
• medication for nerve pain;
• nerve blocks;
• treatment of related muscle tension;
• psychological support for chronic pain;
• surgery in carefully selected entrapment cases.

Repeated strengthening exercises are not always helpful. When pelvic-floor muscles are overly tight, relaxation and coordination may be more appropriate.

Therapy may include:

• breathing exercises;
• relaxation training;
• gentle stretching;
• posture changes;
• manual techniques;
• education about bowel and bladder habits;
• gradual return to sexual activity.

Internal examination or treatment should occur only after explanation and consent.

• genital touching;
• vaginal penetration;
• anal penetration;
• erection;
• ejaculation;
• orgasm;
• prolonged sitting after sexual activity.

Helpful adjustments may include:

• avoiding painful pressure;
• changing positions;
• using lubrication;
• taking breaks;
• choosing nonpenetrative activities;
• seeking specialized treatment.

Pain should not be ignored or treated as a normal requirement of sexual activity.

• persistent genital or perineal pain;
• numbness or tingling;
• pain that worsens while sitting;
• sudden changes in sexual sensation;
• bladder or bowel-control problems;
• pain after childbirth, surgery, or trauma.

Urgent care may be needed when pelvic numbness occurs with severe back pain, leg weakness, inability to urinate, or sudden loss of bladder or bowel control.

Pudendal neuralgia always means nerve entrapment.
No. The nerve may be irritated or injured without being mechanically trapped.

The nerve controls erection by itself.
No. Erection depends largely on autonomic nerves, circulation, hormones, and erectile tissue.

Pudendal pain affects only women.
No. It can affect people of any sex or gender.

Kegel exercises always improve pudendal-nerve symptoms.
No. Strengthening may worsen pain when pelvic muscles are too tight.

Genital sensation proves consent.
No. Nerve responses and physical arousal can occur automatically.

1. The pudendal nerve carries sensation from the genitals, perineum, and anal region.
2. A branch of the pudendal nerve supplies the clitoris or penis.
3. Can compression of the pudendal nerve cause pain while sitting?
4. The patient received a pudendal-nerve block for diagnostic purposes.
5. Childbirth may temporarily stretch the pudendal nerve.
6. Pudendal neuralgia can affect sexual comfort and pelvic sensation.
7. Pelvic-floor therapy helped reduce pressure around the nerve.
8. Understanding the pudendal nerve helps readers connect genital sensation with continence, pelvic movement, and sexual function.

Nerve irritation or injury may cause pain, numbness, altered genital sensation, or discomfort during sexual activity. Treatment may improve function, but recovery differs among individuals.

Understanding the pudendal nerve helps people discuss genital sensation, pelvic pain, sexual response, childbirth, and rehabilitation accurately while recognizing that automatic bodily reactions never replace consent.
