A 38-year-old man asks how he can maintain testosterone levels similar to a 29-year-old without shutting down his testicles or natural testosterone production.
02:10
Dr. O’Connor explains that the first issue is determining whether the man is truly natural or has already used testosterone, anabolic steroids, SARMs, testosterone boosters, or other hormonal compounds.
04:48
The hypothalamic-pituitary-gonadal axis is reviewed, including how the brain regulates testicular testosterone production and how sleep, illness, body weight, genetics, and other health factors influence the system.

Dr. O’Connor discusses testosterone boosters, SERMs, SARMs, steroids, and other compounds while explaining the difference between supporting endogenous testosterone and introducing substances that may alter or suppress natural production.
12:38
The discussion turns to factors that naturally lower testosterone, beginning with depression, anxiety, trauma, psychiatric illness, medications, and other mental health issues that can affect hormonal function.

Dr. O’Connor focuses on obesity, insulin resistance, diabetes risk, blood pressure, cardiovascular health, cholesterol, and the ABCDs™ as major factors in preserving long-term health and natural testosterone production.
Video Summary
A 38-year-old man asks how to maintain youthful testosterone levels without shutting down natural testicular function. Dr. O’Connor explains that introducing exogenous testosterone, anabolic steroids, SARMs, or other androgenic compounds can disrupt the hypothalamic-pituitary-gonadal axis and suppress the body’s own testosterone production.
For someone who wants to remain completely natural, the discussion shifts toward preserving the factors that support endogenous testosterone production. Dr. O’Connor reviews total and free testosterone, SHBG, repeated morning testing, normal age-related changes, mental health, sleep, exercise, alcohol and nicotine use, obesity, insulin resistance, and other metabolic influences.
The broader message is that maintaining healthy natural testosterone depends more on preserving overall health than chasing a particular laboratory number. Dr. O’Connor emphasizes staying metabolically healthy, protecting mental health, avoiding unnecessary androgen exposure, controlling the ABCDs™, and understanding that once a man begins using testosterone or anabolic steroids long enough, recovering completely natural testicular function may become increasingly difficult.

Description
Testosterone
Exogenous testosterone is central to the discussion because the member wants youthful testosterone levels without suppressing his testicles. Dr. O’Connor explains that testosterone introduced from outside the body creates negative feedback on the hypothalamic-pituitary-gonadal axis and can reduce or shut down natural testicular testosterone production.
Clomiphene
Clomiphene is discussed as a selective estrogen receptor modulator that can influence hypothalamic-pituitary signaling rather than acting as exogenous testosterone. Dr. O’Connor includes it while explaining that drugs used to manipulate natural testosterone production still alter the hormonal system and should not be confused with remaining completely natural.
Enclomiphene
Enclomiphene is mentioned alongside clomiphene as a selective estrogen receptor modulator that can affect endogenous testosterone signaling. Dr. O’Connor uses it to distinguish medications that stimulate the hormonal axis from exogenous androgens that directly suppress natural testicular production.
Tamoxifen
Tamoxifen is identified as a selective estrogen receptor modulator while Dr. O’Connor distinguishes different drugs within the SERM class. It is mentioned primarily to clarify that not all SERMs are used for the same purpose when discussing manipulation of testosterone and estrogen signaling.
Raloxifene
Raloxifene is discussed as another selective estrogen receptor modulator and is contrasted with clomiphene and enclomiphene. Dr. O’Connor notes its different clinical uses while explaining that medications affecting estrogen receptors should not all be treated as interchangeable approaches to increasing natural testosterone.
Trenbolone
Trenbolone is discussed through an example of a man using it transdermally while claiming he was not using steroids because he was not injecting or taking pills. Dr. O’Connor uses the example to emphasize that route of administration does not change the fact that an exogenous anabolic androgen can suppress natural hormonal function.

Description
Hypogonadal Suppression
Suppression of natural testosterone production is the central concern in this video. Dr. O’Connor explains that exogenous testosterone and anabolic androgens suppress hypothalamic and pituitary signaling to the testicles, which can reduce endogenous testosterone production and eventually lead to testicular atrophy in long-term users.
Depression And Anxiety
Dr. O’Connor identifies depression, anxiety, trauma, and other psychiatric problems as factors that can affect endogenous testosterone and overall health. For men trying to preserve natural testosterone, addressing significant mental health problems is part of protecting normal hypothalamic-pituitary-gonadal function rather than focusing exclusively on hormone numbers.
Obesity
Visceral obesity is presented as one of the most important modifiable threats to maintaining healthy natural testosterone. Dr. O’Connor explains that excess abdominal fat, inflammation, and metabolic dysfunction can accelerate testosterone decline and contribute to broader cardiometabolic disease.
Type 2 Diabetes
Insulin resistance and type 2 diabetes are discussed as major metabolic conditions that can negatively affect natural testosterone production. Dr. O’Connor emphasizes maintaining healthy A1C, fasting glucose, body composition, and metabolic health to help preserve endogenous testosterone as men age.
Hypertension
High blood pressure is emphasized as a major threat to long-term heart, kidney, brain, and vascular health. Dr. O’Connor includes blood pressure within the ABCDs™ because preserving testosterone is far less meaningful if uncontrolled hypertension is progressively damaging major organs.
Key Takeaways
- Men who want to preserve natural testicular function should understand that exogenous testosterone and anabolic androgens can suppress their own testosterone production.
- Natural testosterone should be evaluated using symptoms, total testosterone, free testosterone, SHBG, repeated morning testing, and overall health rather than one laboratory number.
- Depression, anxiety, poor sleep, illness, medications, and other health problems can reduce natural testosterone and should be addressed when evaluating declining levels.
- Visceral obesity and insulin resistance are major modifiable factors that can accelerate the decline of natural testosterone as men age.
- Maintaining healthy natural testosterone depends heavily on mental health, exercise, body composition, metabolic health, sleep, and avoiding unnecessary androgen exposure.
- Once testosterone or anabolic steroids are used long enough, restoring completely natural testicular function may become increasingly difficult.
