For men who want to raise low testosterone without sacrificing fertility, two medications come up again and again: Clomid (clomiphene) and enclomiphene. Both work with the body’s own hormonal signaling to boost testosterone naturally — and crucially, both do so without the fertility suppression that comes with standard testosterone replacement. They’re closely related, but not identical, and the differences can matter when choosing the right option.
Dr. Justin Houman is a board-certified urologist, Fellow of the American College of Surgeons, and Assistant Professor of Urology at Cedars-Sinai Medical Center, fellowship-trained in male reproductive medicine at UCLA. Because these medications sit at the intersection of testosterone and fertility, his reproductive-medicine background is exactly the expertise they call for — knowing not just how to raise testosterone, but how to do it while protecting a man’s ability to have children. His work in men’s health has been featured in national outlets including Men’s Health and the New York Post.
I was sent to Dr. Houman from another Urologist that was pretty confused about my situation. Dr. Houman’s team scheduled me quickly, and once we met, Dr. Houman took action immediately. He has a great team that is very nice. He is very personable, listens, jumps right into the trenches, explains everything, and is very responsive. I love working with Dr. Houman, definitely the best Doctor I’ve had!
What Is Clomiphene (Clomid)?
Clomiphene, sold under the brand name Clomid, is a selective estrogen receptor modulator (SERM) that has been used for decades. It works by blocking estrogen receptors in the hypothalamus, prompting the brain to release more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn signal the testes to produce more testosterone and support sperm production. Importantly, Clomid is FDA-approved to treat infertility in women; its use in men for low testosterone is off-label, though it is widely prescribed by urologists and considered a well-established medical option for fertility-conscious men.
What Is Enclomiphene?
Enclomiphene is the purified, more active isomer of clomiphene. Clomiphene is actually a mixture of two isomers — enclomiphene (the trans-isomer, responsible for most of the testosterone-raising benefit) and zuclomiphene (the cis-isomer, which lingers in the body and carries more estrogen-like effects). By isolating enclomiphene, the aim is to keep the benefit while reducing estrogen-related side effects. Its regulatory status is essential to understand: enclomiphene is not FDA-approved for any condition. It is considered investigational and is available only through compounding pharmacies with a prescription, which means it is not verified by the FDA for dose, purity, or effectiveness.
Clomid vs Enclomiphene: Key Differences
| Clomid (Clomiphene) | Enclomiphene | |
|---|---|---|
| Composition | Mix of two isomers (enclomiphene + zuclomiphene) | Purified trans-isomer only |
| FDA Status | FDA-approved for women; off-label in men | Not FDA-approved; compounded only |
| Estrogenic Side Effects | More likely, from zuclomiphene | Generally fewer |
| Typical Dosing | About 25-50 mg daily (men, off-label) | About 12.5-25 mg daily |
| Track Record | Decades of clinical use | Newer, with more limited long-term data |
| Fertility Effect | Preserves and supports sperm production | Preserves and supports sperm production |
Why These Medications Matter for Fertility
The single biggest reason these medications matter is what they don’t do: unlike testosterone replacement therapy, they don’t shut down the body’s own production or suppress sperm. Standard TRT signals the body to stop making testosterone and sperm, which can impair fertility, sometimes significantly. Clomiphene and enclomiphene take the opposite approach, prompting the body to make more of its own testosterone while keeping sperm production intact. For men who want to feel better and still have children, that distinction is everything. Both are used primarily for secondary hypogonadism, where the signal from the brain — rather than the testicles themselves — is the issue.
Which Is Right for You?
There’s no universal winner. Clomiphene offers decades of clinical experience, wide availability, and lower cost, making it a proven first choice for many men. Enclomiphene may appeal to men who experience estrogen-related side effects on clomiphene or who want a more targeted option, though it carries the trade-offs of being compounded and not FDA-approved. Because both are used off-label in men, Dr. Houman walks each patient through the benefits, the limitations, and the regulatory realities so the choice is fully informed. Lab work and follow-up then guide dosing and confirm the approach is working. For men focused on conception, these medications also pair naturally with a broader male fertility evaluation.
Frequently Asked Questions About Clomid and Enclomiphene
-
No — that’s their main advantage; both raise testosterone by stimulating the body’s own production, preserving sperm rather than suppressing it the way standard TRT does.
-
Clomid is FDA-approved for female infertility, and its use in men for low testosterone is off-label, though it is widely prescribed and well-established for fertility-conscious men.
-
No — enclomiphene is not FDA-approved for any condition; it’s considered investigational and available only through compounding pharmacies, which the FDA does not verify for dose, purity, or effectiveness.
-
Clomid contains two isomers, while enclomiphene is the purified active one; isolating it aims to keep the testosterone benefit while reducing estrogen-related side effects such as mood changes or breast tissue growth.
-
These medications work best for men with secondary hypogonadism who want to raise testosterone while preserving fertility, and a full evaluation determines suitability.
-
Dr. Houman tracks testosterone, estrogen, and other markers with periodic lab work, adjusting the dose and confirming the medication is achieving the desired effect.

Meet Dr. Houman
Expert in Men’s Health with Tower Urology and Cedars Sinai
Dr. Justin Houman, MD, FACS is a board-certified urologist and fellowship-trained microsurgeon at Tower Urology, Cedars-Sinai Medical Center in Los Angeles. His subspecialty training in male reproductive medicine and microsurgery is held by fewer than 2% of practicing urologists in the United States.
His clinical focus is narrow by design. Varicoceles, chronic testicular pain, male infertility, vasectomy, testosterone optimization, erectile dysfunction, penile implant surgery, and Peyronie’s disease are not add-on services here. They are the practice. Patients travel from across the country and internationally for procedures, particularly microsurgical varicocelectomy, spermatic cord denervation, and inflatable penile implant surgery, that require a level of subspecialty training and surgical volume most urology practices do not have.
