Abstract​

Introduction: The study aimed to determine if hepatic steatosis assessed by Fatty Liver Index (FLI) was an independent risk factor for male testosterone insufficiencylow testosterone level and whether the FLI was the strongest risk factor for testosterone insufficiencylow testosterone level in two different age groups.
Methods: Two cross-sectional studies were performed. A total of 3443 male participants (aged 46-75) were recruited into study A (part of lONgitudinal study (REACTION)). Then a total of 267 male participants (aged 25-45) were recruited into study B. Serum TT and sex hormone-binding globulin (SHBG) levels, indicators for assessing hepatic steatosis were measured. The Pearson correlation and regression analysis were performed to investigate the risk factors for testosterone insufficiencylow testosterone level.
Results: The FLI had the strongest negative correlation with serum testosterone in the study A (r=-0.436) and B (r=-0.542). Compared with patients with a FLI lower than 30, the risk for testosterone insufficiencylow testosterone level increased by 3.48-fold in subjects with a FLI higher than 60 adjusted for potential risk factors in study A. In study B, the OR of testosterone insufficiencylow testosterone level in patients with potential hepatic steatosis was 4.26 (1.57-11.60) after adjusted for age and HOMA-IR, and 0.59 (0.14-2.60) after adjusted for age, HOMA-IR, waist circumference, body mass index, and SHBG.
Conclusions: FLI, was the strongest risk factor for male testosterone insufficiencylow testosterone level independent of insulin resistance in a male populations of different ages, however the association can be modulated by SHBG levels in the young.

According to a Washington Post investigation between 2017 and 2021, diagnoses in children under seventeen of nonalcoholic fatty liver disease more than doubled. It’s estimated that 5% to 10% of all U.S. children now have it, making it as common as asthma.

Tying these two studies together.....Sedentary life styles in children is also causing fatty liver disease. Sedentary lifestyles lead to obesity, so that combined with a diet high in sugars seems to be a big culprit which most likely leads to low testosterone.

Non-alcoholic fatty liver disease is associated with higher levels of objectively measured sedentary behaviour and lower levels of physical activity than matched healthy controls | Frontline Gastroenterology

I just learned this.


To calculate the fatty liver index (FLI), you can use the following formula:

FLI = (e0.953×loge(triglycerides)+0.139×BMI+0.718×loge(GGT)+0.053×waist circumference−15.745)/ (1 + e0.953×loge(triglycerides)+0.139×BMI+0.718×loge(GGT)+0.053×waist circumference−15.745) × 100

Where:
- BMI is the body mass index
- GGT is the gamma-glutamyl-transferase
- Waist circumference is measured in centimeters
- Triglycerides are measured in mg/dL

This formula was developed by Bedogni et al. in 2006 and is based on waist circumference, BMI, triglycerides, and GGT levels[2][4][5]. The resulting FLI score ranges from 0 to 100, with higher scores indicating a higher likelihood of hepatic steatosis or fatty liver disease[2][3][5]. The FLI is a non-invasive method of assessing hepatic steatosis and is easy to employ as each individual component is a routine measurement in clinical practice[4][5].
