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
Levels are normally 30–200 ng/dL (1.0–7.0 nmol/L) in females and 40–150 ng/dL (1.4–5.2 nmol/L) in males. In premature infants, serum androstenedione levels hover between 80 and 446 ng/dL. In full-term newborns, levels range from 20 to 290 ng/dL, and between 1 month and 1 year old, serum levels typically stay at less than 69 ng/dL.
Hormones predominate at the left part of the scale, shown with a red at ng/L or pmol/L, being in very low concentration. There appears to be the greatest cluster of substances in the yellow part (μg/L or nmol/L), becoming sparser in the green part (mg/L or μmol/L).
A 2011 Institute of Medicine (IOM) report set the sufficiency level at 20 ng/mL (50 nmol/L), while in the same year The Endocrine Society defined sufficient serum levels at 30 ng/mL and others have set the level as high as 60 ng/mL. [89] As of 2011 most reference labs used the 30 ng/mL standard. [63] [89] [90]: 435

100–200 pg/mL <55 ng/dL [4] Callen-Lorde: United States "Some guidelines recommend checking estradiol and testosterone levels at baseline and throughout the monitoring of estrogen therapy. We have not found a clinical use for routine hormone levels that justifies the expense.
