Enclomiphene Citrate

The Fertility-Preserving Testosterone Therapy Alternative

Restore Your Natural Testosterone Production Without Compromising Fertility

What is Enclomiphene Citrate?

Enclomiphene citrate is a selective estrogen receptor modulator (SERM) that stimulates your body's natural testosterone production rather than replacing it with synthetic hormones. Unlike traditional testosterone replacement therapy (TRT), enclomiphene works by blocking estrogen receptors in the hypothalamus and pituitary gland, which signals your body to produce more luteinizing hormone (LH) and follicle-stimulating hormone (FSH) – the hormones that tell your testicles to make testosterone and sperm.

How It Works

Enclomiphene blocks estrogen receptors in the brain, preventing negative feedback. This causes your pituitary gland to release more LH and FSH, which naturally stimulates testosterone and sperm production in your testicles.

The Science

Enclomiphene is the purified trans-isomer of clomiphene citrate. Studies show it increases total testosterone levels into the normal range (400-600+ ng/dL) within 2-6 weeks while maintaining or even increasing sperm counts.

FDA Status

While enclomiphene is not yet FDA-approved for male hypogonadism, it is available through compounding pharmacies with a prescription. It's used off-label based on extensive clinical research demonstrating its safety and efficacy.

Key Benefits of Enclomiphene

1

Preserves Fertility

Unlike traditional TRT which suppresses sperm production, enclomiphene actually stimulates both testosterone AND sperm production. Studies show men maintain sperm counts of 75-176 million/mL while on treatment – making it ideal for men who want to have children now or in the future.

2

Natural Testosterone Production

Enclomiphene restores your body's own testosterone production rather than replacing it. This means your testicles continue functioning normally, maintaining testicular size and preventing shutdown of your natural hormone axis.

3

Oral Convenience

Taken as a simple daily pill – no injections, gels, or patches required. Most men take 12.5-25mg daily, making it one of the most convenient testosterone therapy options available.

4

Lower Side Effect Profile

Compared to traditional TRT, enclomiphene has fewer side effects. No risk of testicular atrophy, lower risk of elevated red blood cells (polycythemia), and minimal impact on cardiovascular markers when monitored properly.

5

Reversible Treatment

Because enclomiphene stimulates natural production rather than replacing testosterone, stopping treatment allows your hormone levels to return to baseline more easily than with exogenous testosterone.

6

Effective Testosterone Increase

Clinical studies demonstrate consistent increases in total testosterone levels from <300 ng/dL to 400-600+ ng/dL, with some men achieving levels above 700 ng/dL. Most men see improvements within 2-6 weeks.

Who Should Consider Enclomiphene?

Men Planning Families

If you want to have children now or in the future, enclomiphene is an excellent choice since it maintains or increases sperm production while optimizing testosterone levels.

Secondary Hypogonadism

Men with low testosterone due to hypothalamic or pituitary dysfunction (secondary hypogonadism) respond especially well to enclomiphene therapy.

Younger Men

Men under 40 who want to optimize testosterone without shutting down their natural production are ideal candidates for enclomiphene treatment.

TRT Alternative Seekers

Men looking for a less invasive, more natural approach to testosterone optimization who want to avoid injections and potential long-term TRT complications.

Post-TRT Recovery

Men coming off traditional TRT who want to restart natural testosterone production may benefit from enclomiphene as part of a recovery protocol.

Symptom Relief

Men experiencing low testosterone symptoms: fatigue, low libido, erectile dysfunction, mood changes, difficulty building muscle, or decreased motivation.

Frequently Asked Questions

How long does it take for enclomiphene to work? ▼
Most men begin seeing improvements in testosterone levels within 2-4 weeks of starting enclomiphene. Clinical studies show significant increases in total testosterone by 6 weeks, with some men experiencing benefits as early as 14 days. Symptom improvements (energy, libido, mood) typically follow testosterone increases by several weeks as your body adjusts to optimized hormone levels.
What dose of enclomiphene is most effective? ▼
The most commonly studied and prescribed dose is 25mg daily. Some men respond well to 12.5mg daily, while others may benefit from 25mg. Lower doses (6.25mg) have also shown efficacy in research. Your provider will determine the optimal dose based on your baseline testosterone levels, symptoms, and response to treatment. At ZYP Medical, we personalize dosing and adjust based on your lab results and how you feel.
What are the side effects of enclomiphene? ▼
Enclomiphene generally has a favorable side effect profile. Potential side effects may include: mild headaches, temporary visual changes (rare), mood fluctuations during adjustment period, and slight elevation in estradiol in some men. Compared to clomiphene citrate (the mixed isomer), enclomiphene has fewer estrogenic side effects like hot flashes. As with any SERM, there is a theoretical risk of thromboembolic events, though this appears rare in clinical studies. Regular monitoring with lab work helps identify any issues early.
How is enclomiphene different from clomiphene (Clomid)? ▼
Clomiphene citrate (Clomid) is a mixture of two isomers: enclomiphene (62%) and zuclomiphene (38%). Enclomiphene is the active, beneficial isomer that blocks estrogen receptors and increases testosterone. Zuclomiphene, however, has a longer half-life and can accumulate in the body, potentially causing estrogenic side effects. Pure enclomiphene provides the testosterone-boosting benefits without zuclomiphene's drawbacks, resulting in more consistent results and fewer side effects.
Will my testosterone stay elevated after stopping enclomiphene? ▼
No, testosterone levels typically return toward baseline after discontinuing enclomiphene. However, because enclomiphene stimulates natural production rather than suppressing it, recovery is generally easier than stopping traditional TRT. Some men may maintain slightly higher levels than pre-treatment, especially if lifestyle factors (diet, exercise, sleep, weight loss) have improved during treatment. Studies show LH and testosterone effects persist for about 1 week after stopping treatment.
Can I use enclomiphene while trying to conceive? ▼
Yes! This is one of enclomiphene's biggest advantages. Clinical studies demonstrate that enclomiphene not only preserves sperm production but often increases sperm counts. In research comparing enclomiphene to testosterone gel, men on enclomiphene maintained sperm counts of 75-176 million/mL, while those on testosterone gel had counts below 12 million/mL. This makes enclomiphene an ideal option for men actively trying to father children or who want to preserve future fertility.
Is enclomiphene FDA-approved? ▼
Enclomiphene is not currently FDA-approved for male hypogonadism, though it underwent extensive clinical trials and was previously under FDA review. It is available through compounding pharmacies and prescribed off-label based on strong clinical evidence demonstrating safety and efficacy. Clomiphene citrate (which contains enclomiphene) has been used off-label in men for decades with an established safety profile. Many physicians and endocrinologists prescribe enclomiphene based on published research and clinical experience.
What lab work is needed while on enclomiphene? ▼
Regular monitoring is essential to ensure treatment safety and efficacy. We typically check: Total and Free Testosterone, Estradiol (E2), LH and FSH, Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP) including liver function, and optionally Lipid Panel and PSA (for men over 40). Baseline labs are done before starting, then follow-up labs at 6-8 weeks, 3 months, and then every 3-6 months depending on your response and stability.
How much does enclomiphene cost? ▼
At ZYP Medical, enclomiphene therapy is competitively priced and typically more affordable than traditional TRT when you factor in the convenience and fertility preservation benefits. Pricing varies based on dosage and whether you're combining it with other therapies. Contact us for specific pricing information or schedule a consultation to discuss the most cost-effective treatment plan for your goals. We offer transparent pricing with no hidden fees.
Can I combine enclomiphene with other TRT medications? ▼
Enclomiphene is sometimes combined with other therapies depending on individual needs. Some men use enclomiphene alongside HCG (human chorionic gonadotropin) for additional testicular stimulation, though this is less common since enclomiphene already stimulates natural LH. Combining enclomiphene with exogenous testosterone is generally not recommended, as the testosterone will suppress your natural production that enclomiphene is trying to stimulate. Your provider can determine the best treatment protocol based on your specific situation.
What if enclomiphene doesn't work for me? ▼
While most men with secondary hypogonadism respond well to enclomiphene, some may not achieve adequate testosterone increases. Men with primary hypogonadism (testicular failure) typically don't respond as well since the issue is with the testicles themselves rather than the signaling from the brain. If enclomiphene doesn't provide sufficient benefits after 2-3 months, we can explore alternative options including traditional TRT, HCG monotherapy, or combination protocols. At ZYP Medical, we'll work with you to find the treatment approach that best meets your goals.
Does enclomiphene affect estrogen levels? ▼
Enclomiphene can increase estradiol (E2) levels in some men since higher testosterone gets converted to estrogen through aromatization. However, because enclomiphene blocks estrogen receptors in certain tissues, elevated estradiol levels don't always cause symptoms. We monitor estradiol levels regularly and can adjust treatment or add an aromatase inhibitor if needed, though this is less commonly required compared to traditional TRT.
Who is NOT a good candidate for enclomiphene? ▼
Enclomiphene may not be appropriate for: men with primary hypogonadism (testicular failure) who have elevated LH/FSH already, men with severe testosterone deficiency who need immediate symptom relief (TRT may work faster), individuals with liver disease or dysfunction, men with a history of blood clots or thromboembolic events, and those taking medications that significantly interact with SERMs. Your provider will review your medical history to determine if enclomiphene is right for you.
How do I get started with enclomiphene at ZYP Medical? ▼
