Background: Low testosterone levels is associated with higher cardiovascular risk in men with diabetes. However, there are few studies on testosterone levels and the factors affecting them in patients with young-onset diabetes (YOD). The objective of this study was to investigate the correlation between waist-to-hip ratio (WHR) and testosterone levels in men diagnosed with YOD.
Research Design And Methods: This cross-sectional study involved 547 male patients with type 2 diabetes mellitus (T2DM) from the Endocrinology Department of the Affiliated Hospital of Jining Medical University. The participants were divided into two groups: a young-onset diabetes (YOD) group and a late-onset diabetes (LOD) group. Anthropometric measurements, including height, weight, waist circumference, and hip circumference, were recorded. Additionally, fasting blood samples were collected to assess various parameters, such as sex hormone levels and lipid profiles. The association between WHR and testosterone levels was analyzed by univariate linear regression and multivariable linear regression analysis.
Results: Five hundred forty-seven patients with type 2 diabetes and aged 50.3 ± 12.1 years were enrolled in the study. One hundred ninety-three patients were assigned to the YOD group based on a diagnosis age of 40 years or younger, while the remaining 354 patients were assigned to the LOD group. The testosterone was significantly lower in the YOD group compare to the LOD group (P = 0.049), and the WHR had an independent effect on testosterone in men with the YOD group (β=-4.67, P = 0.0251), but there was no evidence of such an association in the LOD group (β =-1.13, P = 0.4608).
Conclusions: According to our results, male patients with YOD exhibited lower testosterone levels compared to those with LOD. Furthermore, their testosterone levels were significantly negatively correlated with WHR. These findings indicate that it is more necessary to screen for testosterone in obese patients with YOD and that improving obesity, especially abdominal obesity, may help to interrupt the vicious cycle of low testosterone-obesity-insulin resistance-hyperglycemia-low testosterone.

Background: Polycystic ovary syndrome (PCOS) is a common endocrinometabolic disorder affecting women of reproductive age, characterized by hormonal imbalances, irregular menstrual cycles, and often, infertility. Hypothalamic amenorrhea, a condition marked by the cessation of menstruation due to disruptions in the hypothalamic-pituitary-gonadal axis, is a frequent manifestation in PCOS. Probiotics, beneficial microorganisms known for improving metabolic health, have shown promise in restoring hormonal balance and enhancing fertility.

The sex-specific development of hippocampal learning in juveniles remains unclear. Using an inhibitory avoidance task, we assessed contextual learning in both sexes of juvenile rats. While sex hormone levels and activating effects are low in juveniles, females showed superior performance to males, suggesting that females have a shorter period of infantile amnesia than males.

The gut microbiome is known to have a bidirectional relationship with sex hormone homeostasis; however, its role in mediating interactions between the primary regulatory axes of sex hormones and their productions is yet to be fully understood. We utilized both conventionally raised and gnotobiotic mouse models to investigate the regulatory role of the gut microbiome on the hypothalamic-pituitary-gonadal (HPG) axis. Male and female conventionally raised mice underwent surgical modifications as follows: (1) hormonally intact controls; (2) gonadectomized males and females; (3) gonadectomized males and females supplemented with testosterone and estrogen, respectively.

Background: Zinc and vitamin E affect the metabolism of testosterone and inflammatory factors. We aimed to evaluate the effect of zinc and vitamin E supplementation on plasma testosterone levels and inflammatory markers in patients undergoing coronary artery bypass graft (CABG) surgery.
Methods: This study was a secondary analysis of a previously published randomized controlled trial in a subsample of male patients undergoing CABG surgery.
