What is the Origin of Exertional Hypogonadism?

This clinical entity was first recognized in the fields of sports medicine and exercise physiology, particularly among endurance athletes and those with disordered eating patterns, as a cause of performance decline and menstrual dysfunction. The term reflects the direct causal link between the magnitude of physical exertion and the resulting endocrine suppression. Understanding this link is vital for optimizing athlete health and training protocols.

What is the Mechanism of Exertional Hypogonadism?

The primary mechanism involves a central inhibition at the level of the hypothalamus, triggered by a combination of high energy expenditure, low energy availability, and elevated stress hormones like cortisol. This physiological stress suppresses the pulsatile release of Gonadotropin-Releasing Hormone (GnRH). The resulting decrease in GnRH subsequently leads to reduced secretion of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) from the pituitary, ultimately lowering gonadal steroidogenesis.

Exertional Hypogonadism

Meaning

A state of suppressed reproductive hormone production, characterized by abnormally low levels of testosterone in males or estrogen and progesterone in females, directly induced by high-volume, intense, or prolonged physical training. This condition represents a physiological maladaptation where the energy demands of excessive exercise supersede the body’s capacity to maintain normal function of the hypothalamic-pituitary-gonadal (HPG) axis. It is a form of functional hypogonadotropic hypogonadism.
