testosterone-level

GROUPED BY AGE AND GENDER

[3]
In the United States, male total testosterone levels below 300 ng/dL from a morning serum sample are generally considered low

A testosterone test checks the level of this male hormone (androgen) in the blood.
Normal

Specialists say that men considering testosterone replacement therapy—whether by injection, patches, cream, gel or oral form—should get their PSA levels checked as testosterone replacement therapy could increase the risk of prostate cancer. (A PSA blood test identifies a man’s risk for prostate cancer.) Other risks associated with hormone supplementation, particularly with injections, include the risk of stroke, an increase in liver toxicity and breast development. Ironically, testosterone supplementation also shuts down the production of sperm.

All men should be brought up to a certain level of testosterone. Minimum levels should be 300 nanograms per deciliter of total testosterone. The mean level for a 40-year-old is 500 nanograms.

Normal values may vary from lab to lab. Your doctor will have your test results in 1 to 2 days.
Total testosterone for males
Age Male

7 months to 9 years -Less than 30 ng/dL (less than 1.04 nmol/L)

10-13 years- 1-619 ng/dL (0.04-21.48 nmol/L)

14-15 years 100-540 ng/dL (3.47-18.74 nmol/L)

16-19 years 200-970 ng/dL (6.94-33.66 nmol/L)

20-39 years 270-1,080 ng/dL (9.00-37.48 nmol/L)

40-59 years 350-890 ng/dL (12.15-30.88 nmol/ L)

60 years and older 350-720 ng/dL (12.15-24.98 nmol/L)

Total testosterone for females
Age Female

1 month to puberty Less than 10 ng/dL (less than 0.35 nmol/L)

7-9 years 1-12 ng/dL (0.04-0.42 nmol/L)

10-13 years 2-53 ng/dL (0.07-1.84 nmol/L)

14-17 years 8-53 ng/dL (0.28-1.84 nmol/L)

Premenopausal 10-70 ng/dL (0.35-2.43 nmol/L)

Postmenopausal 7-40 ng/dL (0.24-1.39 nmol/L)

The testosterone level for a postmenopausal woman is about half the normal level for a healthy, nonpregnant woman. And a pregnant woman will have 3 to 4 times the amount of testosterone compared to a healthy, nonpregnant woman.

Normal free testosterone levels in men range from 44 to 244 pg/mL (0.68 to 3.76 pmol/L).
In women, the free testosterone level may range from 0.6 to 9.2 pg/mL (0.01 to 0.14 pmol/L).

[2]
Jon Kaiser, M.D., author of Healing HIV, suggests that for peak health we should be in optimal ranges of 500 to 1000 ng./dl. of total testosterone levels for men, and 50 to 100 ng./dl. of total testosterone levels for women.

Testosterone can be measured as “free” (that is, bioavailable and unbound) or more commonly, “total” (including the percentage which is chemically bound and unavailable).
In the United States, male total testosterone levels below 300 ng/dL from a morning serum sample are generally considered low
