Sexual dysfunctions

Male sexual dysfunctions

Sexual dysfunctions are quantitative and qualitative disorders of sexual performance in the areas of sexual appetence, sexual arousal, orgasm and sexual satisfaction. This category is understood by different authors in different ways. Impact is given in the literature on the functional or psychogenic nature of sexual dysfunctions, as well as on the biologic or aetiologic causes.

The incidence of sexual dysfunctions in the population is not known precisely. Undeniably, the majority of these disorders in their milder form occur, at least once in their life, to most people. In a survey of sexual behaviour of a representative sample of Czech population, 17% women and 19% of men admitted to have suffered from a sexual disorder somewhere in their life. In the same survey, 11% of women and 15% of men stated to have sexual problems at present.

Sexual dysfunctions can be classified into primary or secondary. Primary dysfunction means that the patient is affected at the beginning of his sexual life. Secondary dysfunctions occur after a certain period of trouble-free sexual life.

Sexual dysfunctions may have organic or psychological causes. The organic causes are neurogenic, hormonal, venous, drug-related or multifactorial in consequence of generalized disease of anatomic anomalies. Psychogenic dysfunctions include a whole array of causes from insufficient stimulation, disturbing experiences from the past, childhood education, problems in partnership, to personal features (neuroticism) and personality disorders.

Sexual dysfunctions can be complete or partial. Complete sexual dysfunction means practical lack of a physiologic sexual quality. For example, missing firm erection, lubrication, ejaculation, orgasm. Partial dysfunctions are those in which the corresponding sexual function is impaired only to a certain extent. These namely include conditions when the disorder manifests itself only in negative circumstances or unusual situations (e.g. unreliable erection, meager lubrication, occasional lack of orgasm).

Sexual dysfunction can be generalized or selective. Generalized dysfunction is not associated with the current partnership and is autonomous with regard to the particular partner. Selective dysfunction is associated with a particular partnership and its quality.

Female sexual dysfunctions

According to the FDS (Female Sexual Dysfunction) Committee at ESSIR (European Society for Impotence Research), the woman's sexual cycle has three degrees:

  • Desire - requires sufficient oestrogen stimulation of the central nervous system, the physiological level of prolactin and the presence of androgens, which ensure sexual arousal and are capable to induce ovulation.
  • Arousal - central, mental activation and imagination leading to non-genital (nipple erection) and genital (clitoral reaction, vaginal lubrication) reaction.
  • Orgasm - represents an altered cognitive condition associated with sensory "euphoric sensations", which are primarily difficult to define. It is followed by muscular motor response of the pelvic floor.

 

Classification of female sexual dysfunction

Lack or loss of sexual desire

Sexual appetence or libido represents the appetite, wish, interest or desire for sexual intercourse and for erotic-sexual activities that precede it or are connected with it. Low sexual appetence is a disorder that only rarely occurs isolated.

Sexual aversion

Sexual aversion is the aversion to sexual activity. While in frigidity the attitude towards sexual activity is indifferent, in aversion it is permanently highly negative. The aversion can be directed solely to the coitus itself, or it can be generalized to any physical contact of the partner. Some women even survive coitus better than the contact foreplay. This tactile aversion is usually associated with problems related to the partner or with specific sexual traumas. To primary sexual aversion contribute education and adolescence or childhood experiences (e.g. sexual abuse). Secondary aversion can follow the period of forced sexual activity not corresponding in the frequency or manner to the woman's need.

Diminished sexual arousal (frigidity)

It is a relatively frequent dysfunction occurring in women of all age categories. In this condition, the woman has problems with reaching and maintaining sufficient tumescence of the genitals during sexual intercourse. It is the insufficiency of the basic sexual emotion - sexual arousal.

Orgasm disorders

It is a well-known fact that the orgasm in women is much more vulnerable to various situational and external effects than orgasm in men. Woman is more demanding in her sexuality towards her partner, she is more selective. It is not an exception that a woman experiences her first sensual climax after 30 years of age, be it coital, non-coital or masturbation orgasm. Even after reaching the first orgasm, about one third of women have problems with this emotion. As much as 8% of women, i.e. almost each 10th woman, never experience orgasm in all their life.

Dyspareunia

These are conditions of coital discomfort, during which frictional coital movements of the penis in the vagina provoke unpleasant sensations (dyspareunia) or even pain (algopareunia).

Vaginismus

Vaginismus is a sexual dysfunction characterized by strong tightening of the musculature of the vaginal opening. This condition is involuntary, manifests itself by ring-like spasms of the vagina during attempted dilatation. Dilatation is strongly painful. Typical vaginal spasms are occasionally accompanied with adverse reactions to the emission attempts, or with reluctance and repugnance for any touch to the genitals.
