Adipose Tissue Dysfunction and Obesity-Related Male Hypogonadism

Abstract: Obesity is a chronic illness associated with several metabolic derangements and comorbidities (i.e., insulin resistance, leptin resistance, diabetes, etc.) and often leads to impaired testicular function and male subfertility. Several mechanisms may indeed negatively affect the hypothalamic–pituitary–gonadal health, such as higher testosterone conversion to estradiol by aromatase activity in the adipose tissue, increased ROS production, and the release of several endocrine molecules affecting the hypothalamus–… Show more

“…Excessive amounts of adipose tissue, particularly in the visceral depot, favors the development of hypogonadism through several mechanisms. One is the increased aromatase activity that converts testosterone to estrogens that may lead to further peripheral fat accumulation, both by increasing the concentration of estrogens and reducing LH-induced testosterone production [ 48 ]. Another mechanism is the increased release of pro-inflammatory cytokines by dysfunctional adipose tissue that suppresses the release of gonadotropin hormones, particularly LH, with a concomitant decrease in testosterone production [ 49 ].…”

“…Em relação à população masculina, dados mostram que a prevalência de hipogonadismo em homens adultos com peso normal é de cerca de 32%, enquanto cerca de 75% dos indivíduos com obesidade grave (IMC > 40 kg/m 2) têm hipogonadismo (Genchi et al, 2022). Além disso, o hipogonadismo secundário da obesidade masculina (MOSH) representa uma disfunção endócrina com prevalência relatada de cerca de 45% na obesidade moderada-grave (Di Vincenzo et al, 2018).…”

“…Nesse contexto, a perturbação do eixo HHG se torna um dos pontos fisiopatológicos centrais. O tecido adiposo pode participar diretamente na privação androgênica tanto pelo sequestro de testosterona da circulação sistêmica quanto por sua conversão em estradiol, e indiretamente pela redução do estímulo hipotalâmico na síntese de testosterona (Genchi et al, 2022). A respeito da conversão de testosterona em estradiol, é comprovado que a regulação positiva da aromatase é proporcional à massa de gordura corporal em cada indivíduo (Genchi et al, 2022).…”
