Fat-totally free mass, measured of the under water weigh, didn’t change rather within the guys searching brand new twenty five- otherwise 50-milligrams testosterone amount, however it improved amount dependently from the high amounts (Table3). 0001) and you can coordinated which have diary full testosterone concentrations throughout the medication (r = 0.73, P = 0.0001, look for Fig. 2).
Philosophy for each big date depict the brand new imply (±SE) of all offered philosophy thereon big date. Although not, the change represents the essential difference between coordinated values just. Ratios of total body water reviewed by deuterium h2o dilution so you’re able to fat-100 % free bulk counted of the underwater consider had been determined for 
each and every subject and you will averaged across subjects inside for each and every group. DEXA, dual-opportunity X-beam absorptiometry.
Changes in fat-free mass, measured by DEXA scan, were qualitatively similar to those obtained from underwater weighing (Table3, Fig. 1). The measurements of fat-free mass by DEXA were highly correlated with values obtained from underwater weighing (r = 0.94, P < 0.0001).
Fig. 1.Change in fat-free mass (A), fat mass (B), leg press strength (C), thigh muscle volume (D), quadriceps muscle volume (E), sexual function (F), insulin-like growth factor I (G), and prostate-specific antigen (H). Data are means ± SE. *Significant differences from all other groups (P < 0.05); ?significant difference from 25-, 50-, and 125-mg doses (P < 0.05); +significant difference from 25- and 50-mg doses (P < 0.05); and ?significant difference from 25-mg dose (P < 0.05).
To choose perhaps the noticeable changes in lbs-100 % free mass because of the DEXA check always and you may under water weigh depicted fluid retention, we mentioned full human anatomy h2o and compared new ratios from full human anatomy liquids to fat-100 % free size before and after procedures in each class. The new percentages off overall looks liquid to help you fat-100 % free mass by under water weighing didn’t significantly transform which have medication in almost any cures classification (Desk 3), proving your apparent upsurge in weight-free mass measured from the under water consider failed to represent water retention in excess of you to definitely of the proteins accretion.
Lbs bulk, measured by the underwater consider, increased significantly in the men searching the brand new 25- and 50-milligrams dosages but did not improvement in people acquiring the greater dosages of testosterone (Table step three, Fig. 1). There is an enthusiastic inverse relationship anywhere between change in fat mass by under water weigh and you can journal testosterone density (r = ?0.sixty, P = 0.0001, Fig.2).

The fresh correlation coefficient, r, try calculated utilising the logarithmic model, Y = an effective +b · X, where X = diary (T), and a andb depict new intercept and you can mountain.
Muscle mass dimensions.
The brand new thigh strength volume and you may quadriceps muscles volume don’t notably improvement in people finding the latest twenty five- or 50-mg doses however, enhanced dosage dependently at the large doses away from testosterone (Table4, Fig. 1). The alterations during the leg muscles and you can quadriceps muscle quantities synchronised that have diary testosterone accounts during the medication (roentgen = 0.66, P = 0.0001, and you may roentgen = 0.55, P = 0.0001, respectively, Fig. 2).
Values (inside the cm step 3 ) on each big date show the brand new indicate (±SE) of all readily available thinking on that big date. not, the alteration signifies the essential difference between matched values merely.
Muscle results.
The leg press strength did not change significantly in the 25- and 125-mg-dose groups but increased significantly in those receiving the 50-, 300-, and 600-mg doses (Table 5). The changes in leg press strength correlated with log testosterone levels during treatment (r = 0.48, P = 0.0005, Fig. 2) and changes in muscle volume (r = 0.54,P = 0.003) and fat-free mass (r = 0.74,P < 0.0001).
