Testosterone & Estrogen in Women: High vs Low vs. Normal Levels

Testosterone Levels by Age Chart: What is Normal?

However, your levels generally stay high for the next couple of decades. Just like it can be too low, your testosterone can also be too high, and that’s equally problematic. When your testosterone levels are getting into the 1,000 up to the 1,500 ng/dL range—and staying up there—that’s too high, says McDevitt. “Guys tell me they feel a little anxious, which is completely new,” says McDevitt. “Testosterone has a mood stabilizing effect, so as it decreases, anxiety can arise.” There are a couple of science-backed ways to help you boost testosterone levels naturally.

High testosterone levels in males are most commonly caused by taking testosterone replacement or using anabolic steroids. Unfortunately, doctors don’t know if the theoretical benefits of testosterone can be realized in practice; well-designed, long-term studies have not been performed. And because federal funding agencies think the potential risks of testosterone therapy may outweigh the potential benefits, those studies may be a long time in coming. Cultural expectations and peer pressures certainly account for many behavioral differences between the sexes. But hormones also play a role; in particular, testosterone contributes to aggressive behavior, especially in high doses. Neuroscientists are also beginning to assemble data pointing to structural and functional differences in the brains of men and women. For example, scientists in Germany reported that men and women use different parts of their brains to navigate their way out of a maze — and that men are about 28% faster at navigation.

Randomized controlled trials (RCTs) were sought for effectiveness questions, whereas both randomized and non-randomized studies were sought for adverse events and questions of association and risk factors. Random effects meta-analyses were performed when deemed appropriate. Evidence tables (for included studies) and evidence profiles (showing estimates of effect for the outcomes of interest) were generated and presented to the Panel.

Testosterone plays important roles in reproduction and lipid and glucose metabolism in both males and females. Testosterone levels can also be a factor in disease risk, including the development of chronic diseases like cardiovascular disease, diabetes, metabolic syndrome, and osteoporosis. Testosterone levels begin to gradually decline in males, starting in their 40s and 50s.

This would put the number of women with decreased libido in the tens of millions in this country alone. How many of these women have decreased androgens is unknown, but the number is estimated to be between 10 and 15 million. Testosterone is a natural hormone produced primarily in the testicles, and it helps men maintain everything from bone density and body hair to sex drive and sperm production. However, you don’t have to hit a certain number or level despite what the constant flow of ads may tell you. But we’re beginning to see more men in their 20s with low-T at the UT Southwestern male urology clinic. Sometimes low-T is caused by medical conditions, such as genetic diseases or past chemotherapy or radiation therapy.

By understanding your serum testosterone level, healthcare providers can low testosterone cause low sperm count gain valuable insights into your hormonal health and develop a personalized treatment plan tailored to your specific needs. The testosterone levels by age chart offers a framework for understanding hormonal changes. AlphaMD is committed to assisting you in managing these changes for a healthier, more fulfilling life. If you’re concerned about your testosterone levels, our online TRT therapy and expert team are here to support you every step of the way. Testosterone levels begin to decline when you reach your mid-30s, and drop further as you age. Age, genetics, and lifestyle should be factored in to determine what is normal for you.

If you have symptoms of testosterone deficiency, by all means, check your levels and consult your doctor. Otherwise, be reassured that testosterone levels can gradually decline as you get older. One study that looked at over 50,000 male blood samples found there was only a very gradual decline in testosterone levels from age 30, but this decline was more noticeable from age 80. Testosterone has different functions at different stages of your life.

With stabilized mood and improved outlook, TRT can significantly enhance one’s quality of life. Testosterone Replacement Therapy (TRT) is available in several delivery methods, each with distinct advantages and considerations. The choice may depend on an individual’s lifestyle, preferences, and medical needs.

Study populations in individual trials included in any meta-analysis have a significant impact on the reliability of outcomes. Actual patient scenarios will require individual adaptation with variability in expected outcomes. It also highlights that treating clinicians should have specific endpoints for treatment in mind, with regular monitoring of these outcomes to assure that ongoing therapy is warranted and effective.

As noted previously, the harmonization procedure reduces but does not entirely remove the intercohort variation in mean testosterone levels. The observed cross-sectional trend suggesting decrease in testosterone concentrations with age is of lesser magnitude than the corresponding within-individual trend observed previously (31). For each cohort and age range, we obtained simple sample quantiles as estimates of their population counterparts using a method that is median unbiased and robust to statistical transformation (25–27). All population centiles were estimated simultaneously, permitting restriction such that centile curves do not cross (e.g., estimates of the 40th percentile are no greater than those of the 50th at all ages). Key lifestyle modifications support healthy testosterone production, including consuming a nutrient-rich diet with adequate protein and healthy fats, along with regular strength training and cardiovascular exercise. Prioritizing quality sleep of 7-9 hours nightly, managing stress through practices like meditation, and maintaining a healthy weight all work together to optimize hormone production and balance.
