Units for levels

Section Biochemistry: Levels gives typical levels only in units of ng/dL. In most countries afaik the commonest unit is nmol/dL (nanomoles/deciLitre) or similar; a typical lab report I have seen from Canada has only nmol/dL and does not give a conversion factor. The equivalent ranges should be included here, as is common in other WP medical articles. Note that because nmol/dL is a parametric unit there is no general conversion (like metres to feet), so each article/substance requires explicit conversion.

my recent test result from my GP in the UK is also in nmol/L 46.33.143.125 (talk) 10:09, 13 June 2025 (UTC)[reply]

Wrong fraction for albumin bound testosterone

The article claims: "While a significant portion of testosterone is bound to SHBG, a small fraction of testosterone (1%-2%) is bound to albumin." When translating the source "Testosteron Liber" for this claim, it is clear that the low percentage pertains to free testosterone, not albumin bound. The translation " Normally, approximately 60% of circulating testosterone is bound with high affinity to sex hormone binding globulin (SHBG). The remaining amount, with the exception of a percentage of 1-2% (the free fraction), is weakly bound to albumin" Other sources like https://pmc.ncbi.nlm.nih.gov/articles/PMC6371759/ confirm this: "Testosterone is 97.0–99.5% bound to SA[Serum albumin] or sex hormone-binding globulin (SHBG). In humans, 53–55% of testosterone is bound to SASerum albumin, 43–45% is bound to SHBG, and the remaining fraction is free in the bloodstream." BartYgor (talk) 12:37, 4 May 2025 (UTC)[reply]

Incorrect information.

In this paragraph:

Excessive levels of testosterone in men may be associated with hyperandrogenism, higher risk of heart failure, increased mortality in men with prostate cancer, and male pattern baldness.

Dihydrotestosterone(DHT) cause male patern baldness, not testosteron directly. 185.156.38.104 (talk) 12:30, 23 July 2025 (UTC)[reply]
