What is the Origin of Libido Loss?

The term libido is Latin for "desire" or "lust," and its use in a psychological and physiological context was popularized by Sigmund Freud. Its clinical relevance in endocrinology is tied to the discovery of sex hormones, specifically androgens like testosterone, as primary biological drivers of sexual desire in both men and women. The loss of this drive is fundamentally a decline in a core neurobiological function.

What is the Mechanism of Libido Loss?

The mechanism is complex and multifactorial, but hormonally, it is often directly correlated with suboptimal levels of circulating androgens, particularly free testosterone, which is essential for central nervous system stimulation of desire. Furthermore, chronically elevated stress hormones, such as cortisol, can suppress the hypothalamic-pituitary-gonadal (HPG) axis, thereby lowering sex hormone production and diminishing libido. Psychological factors like stress and depression also modulate neurotransmitters like dopamine and serotonin, further impacting sexual motivation.
