Testosterone is often thought of as the hallmark “male hormone,” yet it plays vital roles for both sexes throughout their lives. From puberty and sperm production to maintaining muscle mass, bone density, and fat metabolism, testosterone plays a significant part in nearly every area of our health imaginable – from puberty through puberty; maintaining bone density to fat metabolism. But testosterone levels don’t remain constant; they vary with age, health status and other factors – understanding these changes and their implications is key in order to better navigate symptoms and conditions more successfully.
Testosterone Levels Over Time
Over time, testosterone levels tend to vary considerably from person to person, so here we’ve broken them down by age group.
Infancy and Childhood (6-10 Years)
Boys and girls tend to experience testosterone levels between 1-3 ng/dL during these years as their bodies establish themselves.
Adolescence & Early Adulthood
-
Men: Testosterone levels increase dramatically during puberty, reaching its peak between 17-20 years (around 516 ng/dL) by late teens (17-20). They then stay around 409-575 ng/dL until adulthood (20s).
-
Females: For females, testosterone levels tend to gradually increase with age until reaching around 30 ng/dL by age 20. After which point, levels typically remain stable around 14 years of age.
Adulthood (30-64 Years)
-
Males: At age 30, testosterone begins a gradual decline, usually dropping about 1-2% each year, which equates to approximately 100 ng/dL per decade. By mid-30s levels are usually between 352-478 ng/dL, while by 40s they have declined further to 350-473 ng/dL.
-
Females: In females, testosterone levels typically range between 15-45 ng/dL throughout adulthood; however, conditions like Polycystic Ovary Syndrome (PCOS) can increase these levels significantly.
Older Age (65 Years and Beyond)
-
For Men: With age comes a steady decline in testosterone levels for older men, causing their testosterone levels to fall significantly below 300 ng/dL and trigger hypoandrogenism – an anti-androgen condition known as hypoandrogenism.
-
Females: After age 25, women’s testosterone levels begin to steadily decline; postmenopausal levels typically dipping by approximately 50% from what was seen during young adulthood.
Signs of Abnormal Testosterone Levels
Abnormal testosterone levels, whether too little or too much, can result in noticeable symptoms that manifest themselves through noticeable symptoms.
Men with Low Testosterone levels
Men who suffer from low testosterone may experience:
-
Reduced Libido and Erectile Dysfunction
-
Decreased Muscle Mass and Bone Density
-
Increased Body Fat, especially around the Belly
-
Gynecomastia (enlarged Breast Tissue)
-
Low Sperm Count/Infertility
-
Anemia with Low Red Blood Cell Count
Females With Elevated Testosterone Levels
Women typically exhibit symptoms of increased testosterone production as:
-
Hirsutism (excessive hair growth in male-pattern areas like the face or chest)
-
-
Irregular or absent menstrual cycles
-
Thinning or balding male pattern hair
-
Difficulties with fertility or sub-fertility, often seen in PCOS
Testing for Testosterone Imbalance
If you suspect any imbalance, taking a blood test can provide confirmation. Here’s what you need to know about testing:
-
Ideal Time for Testing: Given that testosterone levels peak between 7-10 am after fasting, testing should take place between these hours.
-
What Gets Measured: Labs typically measure total testosterone, free testosterone (the active form), and albumin-bound bioavailable testosterone for accuracy in their tests. Often repeated testing may be necessary in order to get an accurate picture.
Ways to Manage Testosterone Imbalances
Controlling testosterone levels requires both lifestyle changes and medical interventions as needed.
Lifestyle Changes (for both Men and Women)
-
Losing excess weight: Fat cells convert testosterone to estrogen, so losing weight, particularly if your BMI exceeds 25, is key.
-
Exercising: Both resistance training and aerobic exercise can help boost testosterone levels and enhance overall health benefits.
-
Diet: To maintain hormone balance, consume a diet rich in essential nutrients such as healthy fats from olive oil or avocado, zinc and vitamin D.
Hypogonadism (Low Testosterone) affects men in particular.
Men with low testosterone must first identify its source – be it pituitary, testicular, or systemic disease. If testosterone replacement therapy (TRT) is required, injections, gels or patches may be used; however it carries potential cardiovascular risks; therefore regular monitoring of hematocrit, PSA levels, liver function tests, and lipid profiles is key.
Female Hyperandrogenism (including PCOS)
Women suffering from PCOS or who have elevated testosterone levels typically need treatment to address them, including:
-
Weight Loss and Exercisecan both help to decrease insulin resistance and the production of androgens by the ovaries.
-
Hormonal Contraceptivescan regulate menstrual cycles while decreasing testosterone levels.
-
Anti-androgens: Anti-androgen medications such as spironolactone and finasteride can block testosterone’s effects; however, contraception must still be used due to birth defect risk.
-
Metformin: If insulin resistance is an issue, taking Metformin could help improve blood sugar control and help manage your glucose levels more effectively.
Takeaways
Testosterone levels fluctuate naturally throughout a person’s lifetime, often becoming too high or low at certain times of life. Signs of imbalance – either too high or low levels – could indicate potential issues but require morning blood tests for accurate diagnosis.
Lifestyle changes such as improving diet and exercise routines as well as weight loss are the cornerstone of managing testosterone levels effectively. When necessary, medical treatments like testosterone replacement therapy or anti-androgens may offer relief; however, any decision regarding these should always be carefully evaluated for possible risks and benefits.
Testosterone may be one of the most potent hormones present, yet striking a balance is key for optimal functioning.
