Enclomiphene vs TRT

Enclomiphene and testosterone replacement therapy (TRT) both raise testosterone, but they get there in opposite ways. TRT supplies the hormone directly. Enclomiphene is a daily pill that signals your pituitary gland to tell the testes to make more of their own, which in trials kept sperm counts in the normal range. That difference matters most if you might want children, and it comes with trade-offs in evidence, legal status and price.

How each one works

Your pituitary releases two hormones, LH and FSH, that tell the testes to make testosterone and sperm. When testosterone comes from outside the body, the pituitary senses it and turns LH down. The Depo-Testosterone label puts it plainly: endogenous testosterone release is inhibited, and at large doses spermatogenesis may also be suppressed through inhibition of FSH. The Kyzatrex label warns it may cause azoospermia, meaning no sperm in the semen.

Enclomiphene is a selective estrogen receptor modulator. It blocks estrogen’s feedback at the brain, so the pituitary releases more LH and FSH, and the testes respond. It is one of the two isomers in clomiphene: the Clomid label describes clomiphene as a mix of zuclomiphene and enclomiphene.

That mechanism has a limit. Enclomiphene needs testes that can respond. The trials enrolled men with secondary hypogonadism (low testosterone with low or normal LH), not men whose testes are failing.

What the trials show

Enclomiphene

In two parallel phase III trials, overweight men aged 18 to 60 with secondary hypogonadism took enclomiphene or testosterone gel (AndroGel 1.62%) for 16 weeks. All had early-morning testosterone at or below 300 ng/dL on two occasions. Testosterone rose in every group. LH and FSH went up on enclomiphene and down on gel. Sperm concentration stayed in the normal range on enclomiphene, while the gel group showed “a marked reduction in spermatogenesis”.

An earlier phase II trial of 44 men compared 6.25 mg, 12.5 mg and 25 mg doses with gel. After six weeks, morning testosterone averaged 604 ng/dL on 25 mg and 500 ng/dL on gel, a difference the authors found not significant. Enclomiphene also raised LH and FSH above the normal range, and its effects on LH and testosterone lasted at least a week after stopping.

TRT

Testosterone has longer and larger data. In label studies, 81.6% of men on AndroGel 1.62% and 88% on Kyzatrex reached the normal range. In TRAVERSE, 5,246 men aged 45 to 80 with heart disease or high heart risk used testosterone gel or placebo for a mean of 21.7 months. Major heart events occurred in 7.0% on testosterone and 7.3% on placebo, meeting the trial’s safety goal, though atrial fibrillation, acute kidney injury and pulmonary embolism were more common on testosterone. No enclomiphene trial has followed men that long.

Fertility: the main reason to choose

The Endocrine Society recommends against starting testosterone in men who are planning fertility in the near term. Enclomiphene’s trials are the reason clinics offer it to those men: it raised testosterone without the drop in sperm production seen on gel. If you are trying for a child soon, raise this with the clinician before you choose a plan. We cover the options in TRT and fertility.

Legal status

These two treatments sit under different rules.

Testosterone is a Schedule III controlled substance. Online clinics can prescribe it without an in-person exam because of a DEA and HHS temporary rule, 90 FR 61301, which runs through December 31, 2026. Without an extension or a final rule, an in-person evaluation will be required from January 1, 2027.

Enclomiphene isn’t federally controlled, so that rule doesn’t apply to it. Instead, it depends on compounding policy. Androxal, the enclomiphene brand tested in the trials above, was never approved. Enclomiphene citrate is on the FDA’s 503A Category 1 list of bulk substances under evaluation (updated May 14, 2026), which means the FDA doesn’t intend to act against licensed pharmacies that compound it for a prescription while it decides. That interim status can change. Enclomiphene is not FDA-approved, and the FDA hasn’t reviewed compounded versions for safety, effectiveness or quality.

Side effects

Testosterone labels warn about higher blood pressure and red blood cell counts, blood clots, lower sperm counts and, for gels, transfer to children who touch the skin where it was applied. Our testosterone injection page lists the label warnings.

Enclomiphene has no FDA label, so there are no FDA-reviewed warnings. Clomiphene, which contains it, carries label warnings about blurred vision and spots or flashes, which may be irreversible at higher doses or with longer use. Long-term safety of enclomiphene in men hasn’t been established. Strut Health lists liver disease, blood clot disorders, vision conditions, mood disorders and heart problems among the history to share before starting.

PeterMD sells enclomiphene for $278 on a 2-month plan (regularly $345). Price lists for each are at enclomiphene prices and testosterone cypionate prices, and the enclomiphene treatment page lists every provider that prescribes it.

A cheaper relative is worth knowing about. Clomiphene is an FDA-approved generic for women that some clinicians prescribe off-label to men. Hone Health charges $38 a month plus its membership, $193 a month with the $155 Premium tier.

Enclomiphene vs clomiphene

Clomiphene is the older, FDA-approved relative. The Clomid label says it contains between 30% and 50% zuclomiphene, the other isomer, with enclomiphene making up the rest. The head-to-head trials in this guide compared enclomiphene with testosterone gel, not with clomiphene, so they don’t show which of the two works better. Clomiphene’s advantages are FDA approval (for women) and a commercial generic; its label warns about visual symptoms that can be irreversible with higher doses or longer use. If cost or FDA approval matters more to you than the isomer, ask your clinician whether clomiphene is an option.

Which one to discuss with your clinician

Enclomiphene may make sense if you have secondary hypogonadism, want to keep sperm production, or prefer a pill without the controlled-substance rules. TRT may make sense if your testes don’t respond to LH, if you want an FDA-approved product, or if you want the treatment with the larger safety record. Either way, both need a confirmed low testosterone level first: two morning tests below the normal range.

The bottom line

Enclomiphene raises your own testosterone and kept sperm counts normal over 16 weeks in phase III trials; TRT replaces testosterone, is FDA-approved and Schedule III, and lowers sperm production. Online, enclomiphene costs $79 to $197 a month and injections $79 to $183, any membership included, as of October 2026.
