TRT vs Enclomiphene: Which Is Right for You?
Both raise testosterone. They do it by opposite routes, and the difference decides which one suits you.
Testosterone replacement supplies testosterone from outside the body. Enclomiphene prompts your body to make more of its own. The practical consequence — and the reason this choice matters most — is what happens to fertility.
We offer both at our Marietta clinic. Consultations are free and we don’t bill insurance.

How Each One Works
Testosterone replacement therapy
You receive testosterone directly — by injection, cream, gel or patch. Your blood level rises because the hormone is being supplied.
Your body notices. The brain senses adequate testosterone and reduces the signals (LH and FSH) that tell the testes to produce it. Over time, natural production falls and the testes may shrink. Sperm production is suppressed, sometimes substantially, and sometimes it does not fully recover after stopping.
Enclomiphene
A selective estrogen receptor modulator taken by mouth. It blocks estrogen feedback at the pituitary, so the brain reads testosterone as lower than it is and increases LH and FSH output. The testes receive a stronger signal and produce more testosterone themselves.
Because the body is making its own, LH and FSH rise rather than fall, and testicular function and sperm production are preserved rather than suppressed.
The catch: it only works if your testes can still respond. If the problem is in the testes themselves — primary hypogonadism — stimulating them harder achieves little. That is why we measure LH and FSH before deciding, not just testosterone.
Side by Side
| Testosterone replacement | Enclomiphene | |
|---|---|---|
| How it works | Supplies testosterone from outside | Prompts your own production |
| Fertility | Suppresses sperm production | Preserves it |
| Testicular size | Can shrink over time | Maintained |
| Works for primary hypogonadism | Yes | No |
| Works for secondary hypogonadism | Yes | Yes |
| How it is taken | Injection, cream, gel or patch | Oral |
| Controlled substance | Yes, Schedule III | No |
| FDA-approved for this use | Yes | No |
| Typical ceiling on levels | Dose-dependent, can be pushed high | Limited by what your body will make |
Which One Fits
Enclomiphene is worth considering if you have secondary hypogonadism with low or low-normal LH and FSH, you want to preserve fertility now or later, you would rather not inject, or you are uneasy about starting a therapy that suppresses your own production.
Testosterone replacement is likely the better fit if your LH and FSH are already elevated — meaning the pituitary is signalling hard and the testes are not responding — or if you have tried enclomiphene without sufficient response, or if you need levels that your own production cannot reach.
The honest limitation on enclomiphene: it is not FDA-approved. An application was submitted and received a Complete Response Letter in December 2015, and the European regulator issued a negative opinion in 2018. The decision was about whether the trials demonstrated benefit that mattered to patients rather than a safety finding, but the practical position is that it remains unapproved.
It is prepared by a licensed 503A compounding pharmacy. FDA currently permits compounding of enclomiphene under enforcement discretion rather than approval, and that status can change. It has not been reviewed by the FDA for safety or effectiveness for this use. We would rather you know that before starting than find out later.

How We Decide
The decision is made on labs, not on preference alone. Your free consultation covers your symptoms and history, and then we measure total and free testosterone, SHBG, LH, FSH, oestradiol, a full blood count and metabolic markers — from a morning sample, confirmed on a second draw.
LH and FSH are the numbers that separate the two paths. Low or low-normal alongside low testosterone points to a signalling problem, where enclomiphene can work. Elevated LH and FSH alongside low testosterone points to the testes, where it generally will not.
Fertility plans matter too, and we ask. A man who may want children in the next few years faces a genuinely different calculation, and it is better raised at the start than after a year on testosterone.
Testosterone replacement is $100 a month including medication, provider visits and monitoring labs. Enclomiphene is quoted at consultation. Our full price list is published.
Prescribing is by Jena Bryant, APRN, FNP-BC under nurse protocol agreement with Kent Cohen, MD, FACEP. Response varies between patients and no particular outcome is guaranteed. If your labs do not support either treatment, we will tell you and look at what else explains your symptoms — see low testosterone symptoms.
If enclomiphene is the side of this comparison you keep coming back to, our full page on enclomiphene in Marietta goes further into dosing, monitoring, why it is compounded, and where hCG fits.
Testosterone replacement suppresses sperm production in most men, sometimes substantially, and recovery after stopping is usual but not guaranteed. If fertility matters to you now or in the next few years, say so at your consultation — it is one of the strongest reasons to consider enclomiphene instead, and it is much easier to plan for at the start than to address afterwards.
No. An application was submitted and received a Complete Response Letter from the FDA in December 2015, and the European regulator issued a negative opinion in 2018. It is prepared by a licensed 503A compounding pharmacy, and the FDA currently permits compounding under enforcement discretion rather than approval. It has not been reviewed by the FDA for safety or effectiveness for this use.
Sometimes, and it is a planned transition rather than a straight swap. Coming off testosterone suppresses your own production temporarily, and recovery takes time. Your provider will plan the sequence and monitor your LH, FSH and testosterone through it.
Testosterone replacement generally reaches higher levels, because the dose is supplied directly rather than being limited by what your testes can produce. That is not automatically an advantage — the goal is a level appropriate for you, not the highest number achievable.
No. Enclomiphene is taken orally. That is one of the reasons men choose it, though it should not be the main reason — the clinical question is whether your pituitary signalling, not your testes, is the problem.
On your labs. LH and FSH are the deciding numbers: low or low-normal alongside low testosterone suggests a signalling problem, where enclomiphene can work. Elevated LH and FSH alongside low testosterone points to the testes, where it generally will not. We measure both from a morning sample and confirm on a second draw.
