Objective: To determine the effect of testosterone vs placebo treatment on health-related quality of life (HR-QOL) and psychosocial function in men without pathologic hypogonadism in the context of a lifestyle intervention.
Design, Setting, Participants: Secondary analysis of a 2-year randomized controlled testosterone therapy trial for prevention or reversal of newly diagnosed type 2 diabetes, enrolling men ≥ 50 years at high risk for type 2 diabetes from 6 Australian centers.
Interventions: Injectable testosterone undecanoate or matching placebo on the background of a community-based lifestyle program.
Main Outcomes: Self-reported measures of HR-QOL/psychosocial function.
Results: Of 1007 participants randomized into the Testosterone for Type 2 Diabetes Mellitus (T4DM) trial, 648 (64%) had complete data available for all HR-QOL/psychosocial function assessments at baseline and 2 years. Over 24 months, while most measures were not different between treatment arms, testosterone treatment, compared with placebo, improved subjective social status and sense of coherence. Baseline HR-QOL/psychosocial function measures did not predict the effect of testosterone treatment on glycemic outcomes, primary endpoints of T4DM. Irrespective of treatment allocation, larger decreases in body weight were associated with improved mental quality of life, mastery, and subjective social status. Men with better baseline physical function, greater sense of coherence, and fewer depressive symptoms experienced greater associated decreases in body weight, with similar effects on waist circumference.
Conclusion: In this diabetes prevention trial, weight loss induced by a lifestyle intervention improved HR-QOL and psychosocial function in more domains than testosterone treatment. The magnitude of weight and waist circumference reduction were predicted by baseline physical function, depressive symptomology, and sense of coherence.

Pomegranate (Punica granatum) is a widely cultivated fruit historically recognized for its health benefits and is regarded as a nutritional powerhouse. Pomegranate has a unique composition of bioactive compounds including hydrolysable tannins, anthocyanins, and other polyphenolic components. Of those, punicalagin and its subsequent metabolites are the most extensively studied, demonstrating antioxidant, anti-inflammatory, anti-cancer, and anti-nociceptive activity.

Osteocalcin (OCN), a protein predominantly produced by osteoblasts in bone, has emerged as a significant factor in bone metabolism and reproductive function. This article reviews the latest research on the role of OCN beyond its traditional functions in bone mineralisation, particularly its influence on testicular steroidogenesis and male fertility. The structure and modifications of OCN are elaborated upon, highlighting its uncarboxylated form (ucOCN), which is becoming increasingly recognised for its bioactive properties.

Androgen secretion by testicular germ-cell tumors (GCTs) appears to be markedly rare and likely underreported in the literature. This case study highlights a patient with such a rare tumor, underscoring a notable and yet easily avoidable diagnostic oversight in one of the most prevalent cancers among men. We advocate for increased vigilance and the inclusion of specific symptomatic screening for hyperandrogenism of select patients in existing guidelines and, where appropriate, the implementation of standardized hormonal laboratory analyses in both pre- and post-orchidectomy assessments.

Surgical resection of non-functioning pituitary neuroendocrine tumors (NF-PitNET) is associated with new onset hormonal axis (HA) dysfunction, and factors predicting HA dysfunction are controversial, especially in large and giant NF-PitNET. Thus, we evaluated the postoperative hormonal function and assessed factors affecting HA dysfunction in patients with NF-PitNET. This prospective observational study involved 50 patients who underwent endoscopic surgical resection of NF-PitNET in the Department of Neurosurgery (April 2023-March 2024).
