Introduction

Sexual dysfunction is defined as a complication occurring in any phase of the sexual response cycle. The phases of the sexual response cycle include; excitement, plateau, orgasm, and resolution. Sexual dysfunction is extremely common among women and men, and effective treatment is available. However, few individuals seek help as many, even healthcare professionals, are embarrassed and hesitant to discuss the topic.

Sexual dysfunction, although less common in men, still affects 31% of men and has a large impact on the quality of life as well as interpersonal relationships.

Erectile dysfunction ( 5–20% of men) and premature ejaculation (20–30% of men) are the most common male sexual dysfunctions.

Risk factors

• Psychological complications (eg. depression)
• Biological complications (hormonal, neurologic, and/or vascular)
• Increase with age
• Prostate cancer
• Chronic prostatitis/chronic pelvic pain syndrome

Anatomy & Physiology

Bony structures

Pelvic cavity;

• Sacrum & coccyx
• Left and Right innominate bones (ilium, ischium & pubis)
• Pectineal line
• Pubic crest

Musculature

The pelvic floor consists of 3 layers;

Most superficial layer

• bulbospongiosus m.
• ischiocavernosus m.
• superficial transverse perineal m.
• external anal sphincter

The second layer (the urogenital diaphragm)

• deep transverse perineal,
• sphincter urethrae,
• compressor urethrae

Assist with urethral closure during raised intra-abdominal pressure & plays a role in stabilising the pelvis and lumbar joints.

The third layer (the pelvic diaphragm)

• Levator ani (Pubococcygeus & Ischiococcygeus)
• Iliococcygeus,

Contraction of the Levator ani muscles maintain anal continence when contracted and allow the evacuation of bowel when relaxed. It also supports the pelvic organs.

The obturator internus muscle does not form part of the pelvic floor muscles but still has an effect on the elevation of pelvic organs.

The pelvic floor muscles form a dome-shaped structure that enclose the pelvic cavity.

The functions of the pelvic floor muscles include;

1. Stabilising pelvic joints
2. Support internal pelvic organs
3. Voluntary contraction of urethral and anal sphincters
4. Regulate erection, emission and ejaculation
5. Controls continence (urinary & fecal)

Innervation

The innervation of pelvic floor muscles is from sympathetic, parasympathetic, and somatic nerve fibres.

Nerves responsible for pelvic floor functioning;

1. Hypogastric nerve
2. Pudendal nerve
3. Levator ani nerve

Common complications

Erectile Dysfunction

Literature has indicated that between 9-40% of men struggle with erectile dysfunction by age 40 and raises 10% each decade after 40.  Erectile dysfunction is defined as the inability to either obtain and/or maintain a rigid erection sufficient for penetration.

The muscles responsible for erection are; the bulbospongiosus and ischiocavernosus muscles.

Ejaculatory Dysfunction

During ejaculation there occurs contraction of the smooth muscles of the prostate gland and the bladder neck, as well as relaxation of the urethral sphincter.

The muscle responsible for ejaculation is the bulbospongiosus muscle.

Chronic Prostatitis/ Chronic Pelvic Pain Syndrome

Chronic Prostatitis/ Chronic Pelvic Pain Syndrome is defined as pelvic -, abdomen - and genital pain without symptoms of urinary tract infection. This most commonly occurs during or after ejaculation.
