Male Obesity Secondary Hypogonadism

Meaning

Male Obesity Secondary Hypogonadism (MOSH) describes men with excess adiposity leading to low testosterone from impaired hypothalamic-pituitary function, not primary testicular failure. This endocrine disruption stems from metabolic and inflammatory processes linked to obesity.

Context

MOSH impacts the hypothalamic-pituitary-gonadal (HPG) axis. Visceral fat, an active endocrine organ, secretes adipokines and inflammatory cytokines. These substances influence central GnRH and LH pulsatility, suppressing testosterone production.

Significance

Recognizing MOSH is crucial for accurate diagnosis and patient management. Symptoms like reduced libido, erectile dysfunction, fatigue, and mood disturbances often overlap with aging. Low testosterone contributes to decreased muscle mass and increased visceral adiposity, worsening metabolic dysfunction. Proper identification guides therapeutic strategies, improving quality of life.

Mechanism

The primary mechanism involves obesity-induced chronic inflammation and increased aromatase activity in adipose tissue. Aromatase converts androgens into estrogens, elevating estrogen levels. These estrogens exert negative feedback on the hypothalamus and pituitary, suppressing GnRH and LH secretion. Insulin resistance and altered adipokine profiles also contribute to central hypothalamic dysfunction, reducing testosterone synthesis.

Application

In clinical practice, understanding MOSH guides comprehensive management beyond testosterone replacement. Lifestyle interventions, including dietary changes and increased physical activity for weight reduction, are foundational. Pharmacological approaches may include SERMs or aromatase inhibitors. Testosterone therapy is often reserved for those not responding to weight loss or severe symptoms.

Metric

Diagnosis of MOSH typically involves measuring serum total testosterone, free testosterone, LH, and FSH levels, alongside SHBG. Morning samples are preferred due to diurnal variation. BMI and waist circumference are key anthropometric measures. Metabolic parameters like glucose, insulin, and lipid profiles are assessed to evaluate obesity-related metabolic dysfunction.

Risk

Improperly managed MOSH or indiscriminate testosterone replacement carries risks, including sleep apnea exacerbation, erythrocytosis, and potential cardiovascular concerns. Ignoring underlying obesity and solely treating with testosterone may mask the root cause, missing metabolic improvement. Unsupervised use can lead to suppression of endogenous testosterone production, testicular atrophy, and infertility.
