Testosterone is far more than a “sex hormone.” In men, it plays a central role in muscle mass, strength, fat distribution, insulin sensitivity, bone density, mood, cognition, libido, erectile function, and red blood cell production. When testosterone declines below physiologic needs, the ripple effects can touch nearly every system in the body. The real clinical question is not simply how to raise testosterone, but which pathway best fits the root cause, age, fertility goals, metabolic status, and long-term risks.
1) Botanicals: Best for Borderline Low T and Functional Hypogonadism
For men with stress-related, metabolic, sleep-driven, or obesity-associated testosterone suppression, botanicals can be a meaningful first-line strategy, especially when labs are borderline rather than frankly hypogonadal.
The evidence is strongest for:
- Tongkat ali (Eurycoma longifolia) → may improve free testosterone, libido, and stress resilience
- Ashwagandha → can improve testosterone modestly, especially in stressed men and resistance-trained populations
- Fenugreek → may improve libido and androgen symptoms
- Shilajit → limited but promising data on total testosterone support
- Zinc, magnesium, vitamin D → only effective when deficiency is present
I frame these as axis-supportive, not replacement therapies. They work best when low testosterone is secondary to sleep debt, high cortisol, insulin resistance, excess visceral fat, or micronutrient depletion.
2) Enclomiphene: My Favorite Fertility-Preserving Medical Option
For younger men with secondary hypogonadism who want to preserve fertility, enclomiphene is one of the most evidence-based options available.
Enclomiphene is a selective estrogen receptor modulator (SERM) that increases LH and FSH, stimulating the testes to make more of their own testosterone. Multiple randomized trials and a 2025 meta-analysis found that enclomiphene and clomiphene significantly raise total testosterone, often to levels comparable with testosterone gel, while preserving spermatogenesis.
This is where enclomiphene shines:
- boosts endogenous testosterone
- maintains or improves sperm production
- oral administration
- often easier to taper than TRT
- excellent for men with obesity-related or insulin-resistance–associated secondary hypogonadism
This is often the most elegant option when the testes still have capacity and the hypothalamic-pituitary signal simply needs restoration.
3) Growth Hormone Secretagogue Peptides: Ipramorelin or Sermorelin
This is where nuance matters.
Ipramorelin and sermorelin are growth hormone secretagogues, not testosterone therapies. Their main role is to increase growth hormone pulsatility and downstream IGF-1, which may improve:
- sleep quality
- body composition
- recovery
- visceral adiposity
- lean mass retention
These benefits can indirectly improve symptoms commonly blamed on low T. However, the evidence that they meaningfully raise testosterone itself is weak and low quality, and current data do not support using them as primary therapy for true testosterone deficiency.
Clinically, I use these more as adjuncts for recovery, sleep architecture, and body composition, not as a replacement for true androgen restoration.
4) TRT: The Most Direct and Most Powerful Option
When testosterone is clearly low and symptoms are significant, TRT remains the most reliable and evidence-supported intervention.
TRT can improve:
- libido and erectile function
- lean body mass
- visceral fat reduction
- insulin sensitivity
- bone density
- mood and cognition
- anemia related to androgen deficiency
It is still the gold standard for primary hypogonadism and severe secondary hypogonadism.
However, the tradeoffs are important:
- suppresses LH/FSH and sperm production
- requires ongoing monitoring of hematocrit, PSA, estradiol, and lipids
- may worsen fertility
- can increase erythrocytosis risk
- requires long-term commitment in many men
For men who still want children, TRT alone is never my first choice.
My Clinical Framework
I think of the options as a ladder:
- Botanicals + weight loss + sleep + resistance training → borderline cases
- Enclomiphene → secondary low T + fertility preservation
- Peptides (ipramorelin/sermorelin) → recovery and body composition support, not true T replacement
- TRT → confirmed deficiency with clear symptoms and low labs
The art is matching the therapy to the physiology.
Sometimes the most evidence-based “testosterone treatment” is actually fat loss, better sleep, and reversing insulin resistance, which can normalize testosterone naturally in many men with metabolic dysfunction.
The goal should never be chasing a number. It should be restoring energy, strength, metabolic health, libido, confidence, and long-term vitality in the safest and most physiologically appropriate way possible.
