Multicausal Etiology: Hormonal, Cognitive, Relational, and

Hormonal and Neurobiological Factors in Sexual Interest and Arousal

The origins of sexual interest and arousal disorders in women are deeply multifaceted and interconnected.

From a strictly biological and endocrine perspective, hormonal fluctuations play a decisive role.

A decrease in androgens, particularly free testosterone, drastically reduces erotic motivation and inhibits receptivity.

Likewise, the estrogen decline characteristic of menopause, lactation, or the postpartum period impairs pelvic vasocongestion and severely limits vaginal lubrication.

Hyperprolactinemia, for its part, suppresses gonadotropin secretion, thereby eliminating libido.

In addition, thyroid disorders and vascular or metabolic conditions such as diabetes disrupt nerve conduction and genital blood flow.

Finally, the continued use of psychotropic medications—especially serotonergic antidepressants—along with certain antihypertensives, antihistamines, and hormonal contraceptives, directly interferes with the complex central and peripheral neurochemical circuits essential for the proper modulation of the female clinical sexual response.

Cognitive Aspects and Affective-Emotional Processes

In the psychological realm, cognitive and emotional variables have a direct impact on the subjective experience of eroticism.

Dysfunctional beliefs and myths acquired through a repressive upbringing generate feelings of guilt, shame, or anxiety.

Adopting the so-called “spectator role”—characterized by critical and systematic self-observation during intimate contact—diverts cognitive attention away from pleasurable stimuli toward automatic thoughts about performance or appearance.

Dissatisfaction with one’s body image blocks sensory focus and hinders the ability to let go and enjoy the moment.

Similarly, a history of sexual trauma or previous aversive sexual experiences conditions defensive avoidance responses.

At the same time, the presence of altered affective states, such as depressive disorders or generalized anxiety, drastically reduces hedonic capacity and severely inhibits the very central neurobiological mechanisms responsible for activating and sustaining erotic desire.

Relational Dynamics and the Impact of Everyday Stress

Finally, the relational context and contemporary lifestyles significantly influence female erotic functioning.

Communication difficulties within the couple, a sustained lack of emotional intimacy, accumulated unresolved resentments, and ongoing interpersonal conflicts destroy the complicity necessary for intimacy.

Discrepancies in expectations regarding frequency or pressure exerted by the partner can transform sexuality into a routine duty devoid of gratification.

Likewise, untreated sexual dysfunctions within the couple negatively impact a woman’s motivation.

Added to this is the impact of chronic daily stress, severe physical fatigue, and the overwhelming burden of social roles.

The sustained activation of the sympathetic nervous system and elevated cortisol levels inhibit central pleasure signals, drastically interfering with both motivational interest and the peripheral vascular responses necessary for adequate clinical arousal.

Summary

The genesis of female interest and arousal disorder is multifactorial. Physiologically, decreases in androgens and estrogens, hyperprolactinemia, various metabolic conditions, and the use of psychotropic medications reduce motivational receptivity and vasocongestion.

On the cognitive-affective level, adopting the role of a spectator, body dissatisfaction, restrictive attitudes, and anxiety block pleasure. Likewise, a history of trauma and depression centrally inhibit sexual hedonic processing.

Finally, relationship conflicts, a lack of erotic communication, couple dysfunction, and daily stress increase cortisol levels. This stress-induced hyperarousal undermines psychological well-being and restricts female genital arousal.
