Effects of testosterone gel followed by parenteral testosterone undecanoate on sexual dysfunction and on features of the metabolic syndrome: T gel followed by T undecanoate
Open accessAbstract
The effects of administration of testosterone (T) gel, resulting in plasma T levels in the low range of reference values, followed by testosterone undecanoate (TU), producing plasma T levels in the mid-normal range, were measured in 27 hypogonadal men aged 47-74 years. T gel had positive effects on the International Index of Erectile Function, the Aging Males' Symptoms Scale and International Prostate Symptoms Score and on the metabolic syndrome. The improvement was larger when TU was administered and plasma T levels were higher. The reduction in waist circumference and plasma cholesterol were larger with TU than with T gel, while the increases in plasma high-density lipoprotein and sex hormone binding globulin (an indicator of the severity of the metabolic syndrome) were larger with TU than with T gel. Both T gel and TU appeared safe on prostate parameters. Plasma haemoglobin and haematocrit were elevated but remained in the normal range. The assumption that treatment with T is adequate when achieved plasma levels of T are within the reference range is no longer tenable. Some androgen-dependent biological functions require higher plasma T levels than others, and, moreover, these thresholds differ among men.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
