Here is another study on elderly Indian men living in India which showcases a relatively high level of testosterone (795 ng/dl) for their age (62 years old on average) This study is also on men with benign prostatic hyperplasia which is associated with lower levels of testosterone, yet they still display above average levels.

Studies simply don't agree, or are unclear. Even BioLayne, one of those popular bodybuilding YouTube personalities (a pro competitor) has spoken about the fact that numbers "within normal" mean absolutely nothing to muscle growth. 400 ng/dL is as good as 800 ng/dL, according to him. I used to disagree, but now I wonder.

^{It helps with free testosterone. I know that 32.48 is above the range, but free testosterone is what matters the most compared to total testosterone. It’s common to see men with high natural total like myself (850-950) but low free test.}

Testosterone levels in males and females ; Total testosterone Stage Age range Male Female Values SI units Values SI units ; Infant: Premature (26–28 weeks) 59–125 ng/dL: 2.047–4.337 nmol/L

Elevated insulin increases testosterone and suppresses progesterone. All of these things combined lead to hormonal imbalance and high levels of inflammation in the body (measured by CRP- c reactive protein). This leads to the symptoms of PCOS- no ovulation, irregular periods, weight gain, hair loss, hirsutism.

60 to less than 65 years: 0.06 to 0.87 ng/dL. 70 to less than 75 years: 0.06 to 0.82 ng/dL. Circulating testosterone exists in a biologically-active free form and a bound form that is inactive. According to Mayo Medical Laboratories, the normal range for total testosterone in women is 8 to 60 nanograms per deciliter (ng/dL) 1.

Apr 30, 2022 · A normal testosterone level for adult men is around 8.7–29 nmol/L (250–836 ng/dL). Most UK laboratories will use reference intervals similar to this. These values don’t take your symptoms, baseline levels, or age-related decline into account. But your doctor will consider this when interpreting your levels.

I wrote an article about testosterone which includes a table of normal ranges for all age groups including percentiles. For example, if you're aged 35-39: Mean total testosterone - 597 Median total testosterone - 567 [Vermeulen, A. (1996)] Bio-available testosterone 30-39 years: 72-235 ng/dL [Mayo Clinic Test Catalog]
