Aim:
To investigate the level of postprandial triglycerides (TG)s in elderly men with subnormal testosterone level (< or = 11.0 nmol/L) compared to men with normal testosterone level (> 11.0 nmol/L).
Methods:
Thirty-seven men with subnormal and 41 men with normal testosterone aged 60-80 years underwent an oral fat load and TG levels were measured fasting and 2, 4, 6 and 8 h afterwards.
Results:
Men with subnormal testosterone had significantly higher body mass index (BMI) and waist circumference (P < 0.001) than men with normal testosterone. They had significantly higher area under curve (AUC, P = 0.037), incremental area under curve (AUCi, P = 0.035) and TG response (TGR, P = 0.014) for serum-TG and significantly higher AUC (P = 0.023), AUCi (P = 0.023) and TGR (P = 0.014) for chylomicron-TG compared to men with normal testosterone level. Adjusting for waist circumference erased the significant differences between the groups in postprandial triglyceridemia.
Conclusion:
Men with subnormal testosterone have increased postprandial TG levels indicating an impaired metabolism of postprandial TG-rich lipoproteins (TRL), which may add to an unfavourable lipid profile and promote development of atherosclerosis.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
