For example, treating gonadally intact male mice with estradiol impedes excessive fat mass expansion when animals are fed a high-fat diet (HFD) , and ERα knockout male mice develop obesity . In addition, our findings highlight distinct roles for testosterone, DHT, and estradiol in the regulation of total fat mass and fat distribution and reveal that androgen signaling blocks obesogenic adipogenesis in vivo. We observed that castrated mice develop increased fat mass, reduced muscle mass, and impaired glucose metabolism compared with gonadally intact males. This happens as an accumulation of visceral fat pushes out the abdominal wall. The primary driver in men is visceral adiposity, which contains aromatase enzyme that converts testosterone to estradiol. Visceral fat is a significant source of estrogen through aromatase enzyme activity that converts androgens to estrogens. Most circulating estradiol is aromatized from testosterone predominantly in adipose tissue. Testosterone is converted to estradiol by aromatase and dihydrotestosterone (DHT) by 5α-reductase. However, since this study did not evaluate the improvement in MetS due to testosterone replacement for 52 weeks, it was challenging to say that the analysis was done after adjusting MetS accurately. However, as shown in previous studies and our study, testosterone is also closely related to MetS7,19. All of the different forms of estrogen are synthesized from androgens, specifically testosterone and androstenedione, by the enzyme aromatase.citation needed However, during pregnancy this role shifts to estriol, and in postmenopausal women estrone becomes the primary form of estrogen in the body. Thus, estradiol is the most important estrogen in non-pregnant females who are between the menarche and menopause stages of life. During menopause, estrone is the predominant circulating estrogen and during pregnancy estriol is the predominant circulating estrogen in terms of serum levels. Ulsan is an industrial city in Korea with many large companies, which provide health check-ups every 2 years for their employees. MetS also has a close relation with low testosterone7. The causal relationships between testosterone and the age-related changes have not yet been elucidated; however, some studies have established this relationship2. Korea is rapidly becoming an aging society and aging itself is becoming a global health issue. "In this case, any kind of intervention that can have a beneficial effect on health, you could potentially have a huge improvement in quality of life for the individual." This provides the mechanistic picture of how estrogen is being processed, which determines tissue risk and treatment selection, not just what the circulating level is at the moment of the blood draw. The DUTCH complete test measures urinary hormone metabolites, mapping the entire estrogen detoxification pathway including 2-OH, 4-OH, and 16-OH metabolites, their methylation products, and Phase 2 conjugation efficiency. Standard hormone panels measure circulating estradiol and progesterone at a single time point. He published the results of this study in Obesity Pillars. As we age, the amount and distribution of fat in our bodies changes.
