Over the previous few years, males’s well being has lastly been given the eye it deserves, notably on the subject of testosterone ranges and TRT therapy.
Drops in T-levels have been a main concern for males not too long ago, naturally main to many looking for solutions.
Essentially the most distinguished query is: “What are regular testosterone ranges for males?” or “What ought to your testosterone ranges be?” A easy query with a not-so-simple reply. The response you get can largely rely upon who you ask.

The Decline of Male Testosterone Ranges Over Time
Testosterone is the male’s main intercourse hormone. In easiest phrases, it is what makes males, males.
After puberty, this highly effective hormone is launched and circulates by way of the physique, triggering and supporting a mess of male traits, together with;
- Muscle progress
- Intercourse drive
- Power and temper
- Supporting psychological well being
These testosterone ranges will rise quickly, usually peaking of their early 20s. From right here, ranges are comparatively steady till after the age of 30-40. Relying on the individual, after this time, ranges start to drop at 1-2% a yr.¹
Common Testosterone Ranges Of Males Have Dropped Steadily
What makes all this a lot extra worrisome is that males’ T-levels have been dropping as a complete over the previous few a long time.
This is a a lot bigger challenge than this paper can adequately deal with, however dialogue of testosterone ranges could be incomplete with out discussing the general decline in T-levels over time.
There was a monumental examine in 2007 that analyzed information from the Massachusetts Male Growing old Research. This examine had physiological measurements of males over virtually 20 years (1987–2004).¹
They randomly chosen males aged 45-79 at three totally different time factors and in contrast their T-levels.
T1. 1987-1989 (age: 45-71)
- Median: 501 ng/dL
- Interquartile: 392-614 ng/dL
T2. 1995-1997 (age: 50-80)
- Median: 435 ng/dL
- Interquartile: 350-537 ng/dL
T3. 2002-2004 (age: 57-80)
- Median: 391 ng/dL
- Interquartile: 310-507 ng/dL
So right here we see an apparent drop over time. After additional calculations, researchers discovered the median testosterone ranges dropped 56 ng/dL or 11.2% in a decade! Here is what that appears like;
- 1987-1989: A 65-year-old had median ranges of 500 ng/dL.
- 1995-1997: 65yo had median ranges of 444ng/dL.
After evaluation, they concluded, “current years have seen a considerable, and as but unrecognized, age-independent population-level lower in T in American males…”
As such, we’re beginning this complete dialogue utilizing the bottom testosterone ranges in historical past to outline what’s regular.
What Are “Regular” Testosterone Ranges?
At present, a “regular vary” as outlined by the medical group, such because the AUA, can vary wherever from 300-1.000 ng/dL.
That is an enormous vary in itself, suggesting two males can have very totally different ranges – Man A can have 3x the t-levels as Man B, and each are thought-about “regular”.
The place Did “Regular Ranges” Come From?
If “regular ranges” had been based mostly on well being and organic requirements, you’ll assume they’ve been constant through the years and agreed upon. However this isn’t the case.
The AUA (American Urological Affiliation) notes that there are not less than 7 totally different “authoritative” organizations that record totally different cut-offs for regular ranges.²
- American Affiliation of Medical Endocrinologists: 200 ng/dL
- Endocrine Society: 264 ng/dL
- American Urological Affiliation: 300 ng/dL
- British Society of Sexual Medication: 345 ng/dL
- European Affiliation of Urology: 345 ng/dL
- Worldwide Society of Sexual Medication: 350 ng/dL
- Worldwide Society for the Research of Growing old Male: 350 ng/dL
Utilizing these “cut-off” ranges for the decrease finish of “regular” is a completely totally different downside in itself, which we’ll have a look at beneath.
Nonetheless, the place did these numbers even come from? We’ll have a look at two of the extra well-known and instrumental research used to ascertain them.
1. Framingham Coronary heart Research Reference Ranges (2011): In 2011, researchers measured T-levels of wholesome, non-obese 19–40 y/o males and found the next numbers;
- Imply (Common): 723.8 ng/dl
- Median (Center): 698.7 ng/dl
- 2.5 Percentile (Lowest/Lower-off): 348.3 ng/dl
The researchers decided males who had decrease than 348.3 ng/dl had a larger threat of well being problems, equivalent to;
So whereas 348.3 ng/dL is the “threshold”, why use this quantity as “regular”? It is actually the bottom you may go earlier than you are at considerably larger threat of well being problems.
Have you ever seen the basic movie Velocity? The place the motive force cannot drop beneath 50mph? Think about the motive force sits proper at 50mph and everybody acts like every thing is ok.… Would you’re feeling secure?
That is what contemplating 300ng/dl as regular is doing.
In actuality, in response to this examine, 700ng/dl is what we might think about common, and something beneath is thus beneath common.
2. Harmonized Worldwide Reference Vary (2017)- In 2017, a gaggle of researchers examined the info of 4 cohorts of wholesome, non-obese males (US and Europe). They got here up with the next numbers based mostly on percentiles.
- 97.fifth: 916 ng/dL
- ninety fifth: 852ng/dL
- fiftieth: 531ng/dL
- fifth: 303 ng/dL
- 2.fifth: 264ng/dL
Once more, we see the lowest numbers within the 300ng/dL vary, particularly 264ng/dL on this examine – so I guess which means we must always drop the brink?
However after we have a look at the center vary, we see 531 ng/dL. So whereas this has dropped, the typical on this examine is twice as a lot because the decrease threshold.
Why “Regular Testosterone Ranges” Are Deceptive
Above, we noticed there is a large vary for T-levels which can be deemed to be regular. Listed below are 3 the reason why they should not be.
1. Regular Testosterone Ranges Are Age-Impartial (Normal no matter age)- The 300 ng/dL cutoff used applies to all males. This means a 24-year-old is utilizing the identical requirements as their 70-year-old grandpa.
This clearly would not make any sense and is even admitted by leaders in an article revealed in the American Urological Affiliation. ²
- “Testosterone ranges decline with age, but urologists and endocrinologists have used an age-independent cutoff to judge all males.”
- “This 300 ng/dL cutoff was derived from… males older than 45 years of age. This makes it difficult to judge and deal with males <45 years outdated.”
Think about treating hormonal problems with a 23-year-old lady with the identical requirements as a 60-year-old lady. This is clearly not medically conducive, but it surely illustrates the issue men face when looking for guidance. It is ridiculous.
Prior to now few years, this has been addressed, and an try has been made to ascertain age-dependent cut-offs.⁵
- 20-24 years outdated: 409-558ng/dl
- 25-29 years outdated: 413-575ng/dl
- 30-34 years outdated: 359-458ng/dl
- 35-39 years outdated: 352-478ng/dl
- 40-44 years outdated: 350-473ng/dl
2. These “Regular” Numbers Are Statistical. Lots of the numbers used to ascertain ranges account for your complete inhabitants, together with;
- Athletes
- Overweight
- Sedentary
- Sick
This means your T-levels are based mostly on what obese sedentary males are! In consequence, these numbers are purely statistical and have nothing to do with well being.
The average man today is overweight, however that does not imply being obese is “regular” from a well being perspective — it means one thing is very fallacious with weight loss program and bodily exercise to make that “regular”.
3. The Decrease Vary Is The Threshold For Well being. As we talked about above, the decrease vary is not what’s common however quite the decrease threshold. Going beneath this quantity would drastically improve your likelihood of assorted well being considerations.
Really, even being above this degree can current well being points.
For some cause, it has been determined by some within the medical group to bop on this line quite than promote larger, more healthy ranges.
Why “Regular” T-Ranges Aren’t Good Sufficient
Keep in mind after we mentioned numbers are based mostly on statistics and not well being or efficiency? The actual fact is, you might be above the cut-off but nonetheless expertise well being problems – and doubtless will.
A 2015 evaluation checked out accessible information and discovered a threshold for when males start to see an increase in signs.⁶
- Younger Males (<40 years outdated): <400ng/dl
- Center/Older: <317 ng/dL
Nonetheless, after therapy, these signs typically aren’t relieved till 500 or 600ng/dl!
Along with all this, there are 3 issues to think about:
1. The identical examine admits that many points happen on a spectrum; you do not simply get up at some point with out the power to get an erection.
2. Analysis reveals that numerous uncomfortable side effects can current at totally different ranges.
3. Some well being points are continual in nature and have a number of components. These might take months or years to completely develop, with diabetes being instance. Why wait till an individual is pre-diabetic or diabetic to deal with it?
Here is why it is so necessary. As a result of so many within the medical group view these arbitrary thresholds as being regular, males who’ve well being points however have larger numbers are advised there is not any downside. In consequence, they cannot get authorized therapy.
Fortunately, that is starting to alter with the rise in TRT clinics and better education, however this should not nonetheless be a problem.
Regular Testosterone Ranges Are Extra Than Lab Readings
One necessary factor to remember is that low T-levels will not be the problem; signs are. Allow us to clarify.
For instance, for example two 30-year-old males have ranges of 500ng/dl. For this age, it is close to the decrease finish however not beneath the brink. Nonetheless;
- Man A has erectile dysfunction, drop in temper, and low vitality
- Man B feels nice, has a wholesome intercourse life, and could be very lively
Man B most likely would not want to fret about in search of therapy. Alternatively, Man A could also be extra inclined and may have to hunt out a medical answer.
Paradoxically, this challenge illustrates one other challenge with males’s well being in that you could have a well being challenge current to be handled. Once more, why wait till there’s a problem?
Regardless, when you’ve got well being points and are on the decrease finish of the spectrum, hunt down a second opinion in case your physician makes use of a single, arbitrary quantity to diagnose you.
It is lastly time to begin taking males’s well being critically, and this begins with acknowledging the shortage of high quality therapy for his or her hormones. This has been altering, although, offering males with extra choices.
In case you’re a person, get your T-levels checked. When you have
Redefining “Wholesome” T Ranges
So if the present suggestions for regular ranges cannot be trusted to supply optimum well being, what T-levels ought to males have?
The reply lies with recognizing that the decrease “threshold” seemingly doesn’t promote optimum well being in most males. In actuality, we have to decide the decrease threshold of optimum well being.
What Are “Optimum” Ranges?
Now we have established that “regular ranges” will not be “optimum ranges”, what do you have to intention for as a person?
As above, there’s surprisingly no agreed-upon quantity. Nonetheless, we are able to have a look at numerous analysis in addition to practices of TRT services.
– Above, we talked about that males can start to expertise signs decrease than 400ng/dl and start to see reduction at 500ng/dl – 600ng/dl.
– The American Urological Affiliation (AUA) recommends practitioners who prescribe TRT to “modify testosterone remedy dosing to realize a complete testosterone degree within the center tertile of the traditional reference vary.” This equates to 450ng/dl-600ng/dl.
