Male Sexual Dysfunction & Erectile Dysfunction (ED): Causes and Treatment

Male sexual dysfunction is common, treatable, and rarely due to a single cause. It can affect any stage of the sexual response — desire, arousal, erection, ejaculation or orgasm. This guide explains the main types and their causes, and outlines the step-by-step treatment a uroandrologist uses to put things right.

What is male sexual dysfunction?

“Sexual dysfunction” is an umbrella term for any problem that stops a man having a satisfying sexual experience. The main areas affected are:

• Low sexual desire (libido) — reduced interest in sex
• Arousal and erectile difficulty — trouble getting or keeping an erection
• Ejaculation problems — premature, delayed or absent ejaculation
• Orgasm problems — reduced or altered pleasure at climax

Low sexual desire (libido)

Libido is the desire for sex. It can fall for psychological reasons — stress, low mood, relationship strain — or physical ones. As men age, levels of testosterone (the main male sex hormone) gradually decline, which can reduce desire. Men also differ in what they need for arousal: some respond mainly to visual stimulation, others to touch. When desire drops noticeably, it is worth checking for a hormonal cause.

Erectile dysfunction: why erections fail

An erection depends on healthy blood flow into the penis and on the ability to trap that blood under pressure. Problems here — vascular causes — are among the most common:

• Poor arterial inflow (arteriogenic) — reduced blood supply into the penis
• Venous leak — blood drains away too quickly, so firm pressure cannot build up in the erectile cylinders (corpora cavernosa)
• Diabetes and atherosclerosis — narrow, damaged blood vessels reduce inflow; diabetic men are especially prone to this
• Pelvic injury — for example a road-traffic accident that damages the penile (pudendal) arteries

Erections can also fail because of nerve problems (neurogenic), psychological factors such as performance anxiety, or hormonal imbalance — and in many men more than one factor is at play.

Hormonal causes

Hormone imbalances can disturb both desire and erections. The common ones are low testosterone, a raised level of the female hormone estradiol, or a high prolactin level. A simple blood test identifies these, and correcting them often improves symptoms. You can read more in our guide to testosterone and ageing.

Treatment options

There are many effective treatments, chosen to match the cause and severity:

• Oral medicines — PDE5 inhibitors (such as sildenafil and tadalafil), the well-established first-line treatment for erectile dysfunction
• Vacuum erection devices
• Penile injection therapy (intracavernosal injections)
• Low-intensity shockwave therapy and PRP (the P-Shot) — regenerative options that are still considered experimental
• Hormonal correction where a deficiency or imbalance is found
• Psychosexual counselling, especially where anxiety or relationship issues contribute
• Penile implant (prosthesis) surgery — a reliable, permanent solution for severe ED that does not respond to other treatments

A step-by-step approach works best

Sexual dysfunction is best treated as a ladder: a proper evaluation identifies the cause, treatment begins with the simplest effective option, and it steps up only if needed. With this approach, the large majority of men improve. The key is an honest, confidential assessment by an andrologist rather than self-medication.

Frequently asked questions

Is erectile dysfunction curable?

Many cases are substantially reversible, especially those driven by lifestyle, medication, hormones or psychological factors. Others are well managed with treatment ranging from tablets to a penile implant.

Can ED be a warning sign of other illness?

Yes. Because it is often a blood-vessel problem, ED can be an early sign of heart disease or diabetes — another reason to have it evaluated properly.

Which doctor treats male sexual dysfunction?

A uroandrologist — a specialist in men’s urological and sexual health — is the right person to evaluate and treat it.
