Male Sexual Function and Related Disorders

Introduction Sexual Function

Men of various ages, nationalities, and cultural backgrounds are prone to sexual dysfunction. Over the last three decades, significant improvements have been made in our understanding of the physiology and pathophysiology of male sexual function, as well as approaches for investigating and treating it. In the field of physiology, the nature and components of the normal sexual response have been defined, and the functional activities of all penile structures have been elucidated and integrated.

Sexuality is a component of who we are – we are all sexual creatures.

The majority of us express our sexuality through sexual engagement. Most people are sexually active as adults, which can be a wonderful source of pleasure.

Many of us have had sexual dysfunction at some point in our lives. This occurs when our bodily response to sexual stimuli falls short of our expectations. This could be due to an underlying ailment that requires medical treatment. Even if this is not the case, a lack of desire for sexual activity does not always indicate a problem.

However, if your lack of interest in sexual activity or physical response to sexual stimulation causes you anguish, you may be suffering from sexual dysfunction.

Physiology of Sexual Function in Men

Penile anatomy, vascular, and innervation

The penile sensation is principally controlled by the dorsal nerves (somatic), which are branching out of the pudendal nerve. The upper and lower insets illustrate the mechanics of erection and flaccidity. During an erection, trabecular smooth muscle relaxation and arteriole vasodilation occur in a several-fold increase in blood flow, which increases the sinusoidal gaps, lengthening and enlarging the penis.

Somatic and autonomic nerve fibers supply information to the penis. Somatic innervation provides sensory fibers to the penis and motor fibers to the perineal skeletal muscles. Contraction of the perineal skeletal muscles during an erection causes a transient increase in corporeal body pressure above the mean systolic pressure, which contributes to penile hardness.

Normal penile and testicular size in mature males.

Wessells and colleagues (4) have evaluated the normative data on penile size in adult human males. The rise in core adiposity could contribute to the occasionally reported decrease in penile length with age. The tensile strength of the tunica decreases as men age, whereas the tunica albuginea remains the same. There were no corresponding recommendations for penile girth or volume.

Penile erections are controlled locally

The proposed cerebral control of corporeal smooth muscle function. Parasympathetic fibers directly innervate smooth muscle and sinusoidal endothelial cells. Acetylcholine is a parasympathetic neuromodulator in endothelial cells that triggers the synthesis of constitutive endothelial nitric oxide synthase, hence stimulating nitric oxide production.

Normal Sexual Function

Sexual function and responses involve both the mind (thoughts and emotions) and the body (which includes the neurological, circulatory, and hormonal systems). Sexual responses include:

  • Desire (also known as interest or libido)
  • Arousal
  • Orgasm
  • Resolution

Desire (libido)

Desire is the desire to participate in or continue sexual activity. Thoughts, words, pictures, smells, and touch can all stimulate sexual interest or desire. Sexual Desire might be visible from the start or develop gradually as sexual action and stimulation begin.

For men, sexual Function and arousal are frequently linked. Sexual stimulation can elicit excitement, pleasure, and bodily responses (including increased blood flow to the vaginal area). The need for sexual fulfillment grows as sexual activity and connection continue.


Arousal has a subjective component—sexual excitement that is felt and considered. It also has a physical component: an increase in blood flow to the vaginal region. Blood flow may increase without the woman’s knowledge or arousal. Men’s clitoris and vaginal walls enlarge due to increased blood flow. The increased blood flow leads to an increase in vaginal secretions (which give lubrication).

This reflexive response, which produces engorgement and lubrication, takes place within seconds following a sexual stimulus. This response is triggered by the brain sensing anything sexual, regardless of whether it is erotic or subjectively stimulating. Younger women are more likely to experience vaginal tingling and throbbing during this response. As Men age, vaginal blood flow from sexual stimuli declines, but lubrication in response to sexual stimuli may not.


Orgasm is the pinnacle or climax of sexual desire. Muscle tension throughout the body increases just before an orgasm. When orgasm occurs, the muscles surrounding the vagina contract rhythmically. Men can experience many orgasms. Hormones released during orgasm may contribute to the subsequent feelings of well-being, relaxation, or exhaustion.


Resolution is defined as a sensation of well-being and extensive muscle relaxation. Resolution typically comes after orgasm. However, resolution can take time following extremely stimulating sexual activity that does not result in orgasm. Some women can respond to further stimulation practically immediately following resolve.

Treatments of Sexual Dysfunction

There are various treatments available to aid with sexual dysfunction. Some treatments, such as psychotherapy and cognitive behavioral therapy, can be carried out with the assistance of a therapist. Others, including pharmaceuticals, can be taken on their own. Therapists who specialize in sexual dysfunction may employ a variety of treatments to restore sexual function and increase quality of life. Sex therapy, couples therapy, and sexual medication for erectile dysfunction are among the options. Antidepressants, anti-anxiety drugs, and sleep disorder medications are all possible treatments for low libido.

The Psychological and Physical Causes of Male Sexual

The term sexual dysfunction’ covers a wide range of problems. Sexual dysfunction can result from psychological, physical, interpersonal, or social reasons. Cenforce Tablet is a medication that helps men with erectile dysfunction get a firm erection. There are other choices available, including Fildena 100 and Cenforce 25.

Among The Psychological Causes:

  • Stressed because of work or family demands.
  • Have concerns regarding sexual performance
  • Depression/anxiety
  • Unresolved issues regarding sexual orientation.
  • A history of painful sexual or physical events.
  • Issues concerning body image and self-esteem

A variety of physical factors can contribute to it, including:

  • Diabetes
  • Heart disease
  • Liver disease
  • Kidney disease
  • Gynecological surgery
  • Trauma or pelvic injury
  • Nervous system disorders
  • Side effects of medicine
  • Hormonal changes, including those linked with pregnancy and menopause.

Pain due to sexual activity

Dyspareunia causes recurring or persistent pain during sexual relationships. Infections, hormone imbalances, vaginal dryness, and pelvic floor issues are all potential causes. If you are in pain during sex, you may become anxious, avoid sexual activity, and have strained relationships.

Orgasmic Disorders

Men with orgasmic problems may have trouble attaining orgasm, as well as very weak or delayed orgasms. As a result, sexual satisfaction and self-esteem may suffer, as do emotions of frustration, inadequacy, and disappointment. Vidalista 20 might help you attain and maintain a strong erection for an extended period. Tadalista 20 is another dosage option.

Final words

Most Men will experience sexual dysfunction at some point in their lives, including trouble becoming aroused. FSIAD has therapies available, however it can be isolating and distressing at times. Men who are having sexual problems should see a gynecologist, urologist, or sex therapist.

With a prescription, you can purchase it from a reputable pharmacy or store.
