Clomiphene and enclomiphene · Approved for one thing, prescribed for another
Oestrogen-receptor modulators used off-label in men — with one approved and one not.
Medically reviewed by Bernard Garcia, MD
What it is
Clomiphene is FDA-approved for ovulatory dysfunction in women. In men it is prescribed off-label to raise testosterone by stimulating the body's own production, preserving fertility. Enclomiphene, the more active isomer, is not FDA-approved (a 2015 application was not granted) and is available only compounded.
How it works
Both block oestrogen feedback at the hypothalamus, increasing LH and FSH and therefore testosterone. Evidence in men consists of smaller studies; long-term data are limited.
Research status
| Research area | Status |
|---|---|

| Enclomiphene for any use | Not FDA-approved |
| Long-term safety in men | Limited data |
Status reflects published research context only and is not a statement of safety, efficacy, or suitability for any person.
Is it legal?
Clomiphene is FDA-approved for female infertility; use in men is off-label. Enclomiphene is not FDA-approved and its compounding has faced regulatory scrutiny. This is a general note, not legal advice.
Frequently asked questions
Why choose this over testosterone?
It preserves natural production and fertility, which testosterone suppresses. Whether it is appropriate is a provider's decision.
Is enclomiphene legal?
It is not approved; compounded access exists in a regulatory grey area that changes. Ask a provider.
Side effects?
Visual disturbances, mood changes and others are documented for clomiphene. A provider covers what applies.
