What is enclomiphene?
(en-KLO-mi-feen)
Enclomiphene is the active isomer of clomiphene, meaning it contains only the form that binds to estrogen receptors and stimulates LH. Racemic clomiphene (regular clomiphene) contains both active and inactive isomers; enclomiphene is pure active form. It is faster-acting, peaks higher, and clears in 24 hours rather than days. Typical dose: 12.5–25 mg daily or every other day. Used off-label like clomiphene for fertility preservation.
What's in it
- Enclomiphene CitrateRaises your own testosterone signal
Pure active isomer
faster LH rise, cleaner pharmacokinetics
Enclomiphene has a much shorter half-life than racemic clomiphene (24 hours vs. 30+ hours), producing faster LH spikes and clearer on/off kinetics. Some men report faster recovery of natural testosterone on enclomiphene than on regular clomiphene.
Is it right for you?
Who it's for
Men with low testosterone who want to raise their own without injections and keep sperm production.
What sets it apart
The purified active half of clomiphene: the same signal with fewer mood and vision side effects.
Worth knowing before you start
It only works if your testicles can respond. A blood test of LH and FSH before starting tells you.
What to expect
Testicles stay healthy
size and function maintained on testosterone therapy
Sperm production continues
fertility potential preserved even during testosterone use
Faster recovery if you stop
endogenous testosterone and sperm return quickly when therapy ends
Lab monitoring required
LH, FSH, sperm count tracked to ensure response
How fertility preservation works
Day 1
US-licensed physician reviews your fertility goals, testicular health, and plans on testosterone therapy. Discussion of clomiphene vs. enclomiphene vs. hCG or combination.
1Week 1
Start clomiphene 25–50 mg daily or hCG 500–2,500 IU once weekly, depending on your plan. Baseline semen analysis or testicular ultrasound may be ordered to track changes.
2Weeks 4–8
LH and testosterone levels rise as clomiphene/hCG stimulates the testicles. Testicular function is preserved. Sperm production remains normal or improves.
3Month 2–3
Follow-up labs (LH, FSH, testosterone, sperm count). Dose adjusted if needed. If combining hCG with testosterone therapy, check testosterone levels.
4Beyond
Continue fertility support as long as you take testosterone therapy. If you stop testosterone, fertility usually returns within 3–6 months with continued clomiphene/hCG support.

The science of fertility preservation
Enclomiphene is the (Z)-isomer of clomiphene, the form that binds strongly to estrogen receptors. Racemic clomiphene is 50% enclomiphene and 50% zuclomiphene (inactive). Enclomiphene's short half-life means it does not accumulate.
In off-label use for men seeking fertility preservation or faster recovery of natural testosterone, enclomiphene offers pharmacokinetic advantages over racemic clomiphene. Clinical data in men are emerging.
Learn moreImportant safety information and common side effects
Clomiphene, enclomiphene, and hCG are prescribed off-label to preserve fertility and testicular function during testosterone therapy. Common side effects: mild headache, mood changes, abdominal discomfort. Clomiphene and enclomiphene may cause visual changes (blurred vision, floaters) in ~1% of users, report immediately if vision changes occur. hCG carries a small risk of ovarian hyperstimulation-like syndrome in some men if doses are very high. Tell your physician about prior fertility issues, current fertility plans, or any family history of gynecomastia or testicular disease. Stop and seek care for severe vision changes, severe headache, or testicular pain.

Frequently asked questions
How do I take Enclomiphene Capsules?
Taken by mouth, once a day. The starting prescription is 1 capsule (12.5 mg) each time. Your physician sets your own dose and it is printed on your label.
What strengths does Enclomiphene Capsules come in?
The pharmacy carries 3: 12.5 mg, 51 mg, 75 mg. Your physician chooses which one you get.
How much arrives in each shipment?
30 capsules at the starting strength, shipped to your door from a licensed US pharmacy.
Why use enclomiphene instead of regular clomiphene?
Enclomiphene is the pure active form and has a much shorter half-life (24 hours vs. 30+ days for racemic clomiphene). This means faster LH response, no drug accumulation, and quicker recovery if you stop. Some men report better sleep and mood on enclomiphene. If you have had issues with regular clomiphene, your physician may try enclomiphene.
Do I need clomiphene or hCG if I am on testosterone therapy?
Not always. If you are not concerned about fertility or testicular size, and your testosterone therapy is working well, neither is necessary. But if you want to preserve sperm production, prevent testicular atrophy, or plan a family in the future, your physician will recommend one.
Can I use clomiphene and hCG together?
Yes. Some physicians combine them for synergistic fertility preservation: clomiphene stimulates the pituitary (LH/FSH), hCG directly stimulates the testicles (testosterone/sperm). This combination is off-label but used clinically.
If I stop testosterone, will my fertility return?
Yes, usually within 3–6 months if you used clomiphene or hCG alongside testosterone. Without fertility support, recovery can take 6–12 months or longer. This is why fertility preservation on testosterone is important if you plan a family.
How often do I check sperm count or testicular health?
Initial baseline: before starting or at first visit. Then: every 3–6 months on clomiphene/hCG, or annually if on testosterone long-term. Semen analysis is the gold standard for sperm count; testicular ultrasound tracks size.
