Below you’ll find answers to a few commonly asked questions about clomiphene citrate.

Does clomiphene citrate cause certain side effects in males versus females?

No, the drug manufacturer hasn’t reported any side effect information in males.* Currently, clomiphene citrate is only approved to treat infertility in females.* Using it in males would be an off-label use. Off-label drug use means prescribing a drug for a purpose other than what it’s been approved for by the Food and Drug Administration (FDA).

If you have questions about using clomiphene citrate in males, talk with your doctor.

* Sex and gender exist on spectrums. In this article, we use the terms “male” and “female” to refer to a person’s sex assigned at birth.

What is clomiphene citrate’s half-life? How does the drug work?

Clomiphene citrate works to stimulate the pituitary gland to release two hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Increasing levels of FSH and LH is what starts ovulation (the release of an egg).

Clomiphene citrate will start affecting hormone levels right after you take it. Its half-life is about 5 days. This means it will stay in your body for about 25 days.

To learn more about what to expect with clomiphene citrate, talk with your doctor or pharmacist.

How does clomiphene citrate compare with enclomiphene?

Enclomiphene is an isomer of clomiphene citrate. This means they are the same compound, but their atoms are arranged differently. As a result, they can have different properties.

Currently, enclomiphene doesn’t have FDA approval in the United States. In the past, researchers were studying it for male* infertility.

To find out more about how clomiphene citrate compares with enclomiphene, talk with your doctor or pharmacist.

* Sex and gender exist on spectrums. In this article, we use the term “male” to refer to a person’s sex assigned at birth.

Can clomiphene citrate be taken with anastrozole or letrozole?

Possibly. The drug manufacturer hasn’t reported any information about taking clomiphene citrate together with other drugs. But researchers have studied clomiphene citrate with anastrozole or letrozole. More research is needed to know whether this combination is safe and effective.

To learn more about taking clomiphene together with other drugs, talk with your doctor or pharmacist.
