Baseline characteristics of 19 healthy men prior to initiation of study visits. Abbreviations; bmi, body mass index; AVF, abdominal visceral fat; TAF, total abdominal fat; T, testosterone; E2, estradiol; TSH, thyroid stimulating hormone; SHBG, sex-hormone binding globulin; FSH, follicle stimulating hormone; LH luteinizing hormone. Multiply T by 0.347 and E2 by 3.69 to convert to matching international units (nmol/L and pmol/L, respectively). Data are mean ± SD, median and range.
