Dr. Pearlman recommends that men who suspect that they might have Low-T reach out to their health care providers. "With obesity, particularly metabolic syndrome, men are at higher risk of developing other serious chronic medical conditions like heart disease, sleep apnea, type 2 diabetes, and certain cancers," she says. The connection between obesity and low-T presents a bit of a "chicken and egg" situation. Health & FitnessEveryday decisions, like what to eat, when to go to bed, and everything in between that impacts your health and wellbeing.
The purpose of this article is to examine the contemporary data linking testosterone therapy in overweight and obese men with testosterone deficiency to increased lean body mass, decreased fat mass, improvement in overall body composition and sustained weight loss. MOSH is a potentially reversible cause of HPT axis suppression and testosterone deficiency (functional hypogonadism) and hence can be managed with lifestyle measures to achieve significant weight loss, without the need for testosterone treatment.51 Longitudinal data from the EMAS showed that weight loss can increase testosterone levels in obese men. The bidirectional, inverse relationship between increased fat mass and testosterone levels suggests that both weight loss as well as testosterone therapy have the potential to break this vicious cycle. In obese healthy men with mild-to-moderate androgen deficiency symptoms and moderate testosterone deficiency, the improvement in androgen deficiency symptoms achieved with TRT is over and above what is achieved with weight loss alone, with the greatest benefits observed in severely symptomatic men.85 A recent meta-analysis found that TRT significantly improves erectile dysfunction in men with testosterone deficiency and improves the mean IIEF-5 scores by 1.47 and 2.95 for men with baseline testosterone levels of 86 Men with testosterone deficiency and obesity have reduced testosterone levels and weight loss produces increased total testosterone levels 79,78▪. Insulin resistance in testosterone deficiency is mediated by body composition dependent effects, including increased adipocyte differentiation (visceral obesity) and decreased myocyte differentiation (sarcopenia), and body composition independent effects such as increased inflammation (TNF-α, IL-1 and IL-6), decreased adiponectin and reduced mitochondrial function.35,36 Resultant hyperinsulinaemia acts on the kisspeptin neurons to decrease kisspeptin signalling, which, in turn, acts on the GnRH neurons to decrease GnRH release and thereby LH secretion.37
Data reported from three registries 23▪▪,59▪▪–61▪▪, in which long-term testosterone therapy was evaluated in men with testosterone deficiency and varying grades of obesity, suggested that testosterone therapy is effective in producing weight loss in all three grades of obesity. Testosterone therapy increases lean body mass and reduces total body fat mass in men with testosterone deficiency These findings represent strong foundations for testosterone therapy in obese men with testosterone deficiency and should spur clinical research for better understanding of usefulness of testosterone therapy in treatment of underlying pathophysiological conditions of obesity. The implication of testosterone therapy in management of obesity in men with testosterone deficiency is of paramount clinical significance, as it produces sustained weight loss without recidivism. Long-term testosterone therapy in men with testosterone deficiency produces significant and sustained weight loss, marked reduction in waist circumference and BMI and improvement in body composition.
In contrast, relatively little is known about the role of androgens in brown fat, since its potential role in energy expenditure in humans has been recognized only more recently. In addition, local, tissue-specific increases of E2 may not be reflected in circulatory concentrations. Interestingly, diacylglycerol O-acyltransferase 2 (DGAT2), mechanistically implicated in this differential storage,10 is regulated by dihydrotestosterone,11 suggesting a potential role for androgens to influence the genetic predisposition to either the MHO or MONW phenotype. Therefore, the "obesity paradox" remains a hotly debated, but currently still unresolved issue. By 2030, China alone is predicted to have more overweight men and women than the traditional market economies combined. Testosterone therapy may lead to a worsening of untreated sleep apnea and compromise fertility. Low testosterone by itself leads to increasing adiposity, creating a self-perpetuating cycle of metabolic complications.
Your doctor can prescribe testosterone therapy as part of gender-affirming treatment. Supplements aren't the only way to increase your testosterone levels naturally. A review of dozens of clinical trials showed that DHEA supplements do increase blood testosterone levels in men and women. Zinc deficiency has been linked to low testosterone levels.
