Overview

Product & regulatory status

FDA-approved oral prescription drug for female ovulatory dysfunction. Male hypogonadism use is off label.

Estrogen-feedback modulation

Clomiphene alters estrogen feedback and can increase pituitary gonadotropin signalling. Its effects depend on the functioning reproductive axis. [1]

What the evidence shows

Approved clinical context

The Clomid label summarizes clinical investigations in 7,578 patients, with pregnancies in approximately 30%. This historical overall result includes varied infertility circumstances and cannot predict an individual’s chance of conception or live birth. [1]

Male trial with important limits

A 12-week placebo-controlled trial in 78 men with obesity-associated secondary hypogonadism found increased testosterone and improved body-composition measures. One sexual complaint improved, but HDL cholesterol fell; the trial did not establish long-term fertility or cardiovascular outcomes. [2]

What remains unknown

Response depends on the cause of reproductive dysfunction. A hormone increase is not proof of restored fertility or an explanation for every symptom.

Safety

Visual symptoms

The label warns of blurred vision, flashes and other visual disturbances, occasionally prolonged or irreversible. These require prompt clinical review. [1]

Ovarian treatment risks

Ovarian enlargement, hyperstimulation and multiple pregnancy are relevant to ovulation induction; they are not the same risk context as treatment in men. [1]

Match the indication

Evidence for an oral prescription tablet used for ovulatory dysfunction does not make off-label male treatment an approved indication. [1]

Understanding product quality

Compounded drugs are not FDA-approved finished products. Poor preparation can cause contamination or incorrect strength. A catalog entry or a research paper is not a quality assessment of your product. [3]

When to seek urgent help

Severe allergic symptoms such as trouble breathing, throat or tongue swelling, or fainting need immediate help. Call 911 or your local emergency number. This is general emergency information, not a complete list of risks for this compound. [4]

A starting point for discussion

This is not a complete list of adverse effects or interactions. Your health history, other medicines, and the exact formulation matter. Missing safety data is not evidence of safety.

Common questions

Is clomiphene interchangeable with enclomiphene?

No. Clomiphene includes enclomiphene and zuclomiphene, which have different pharmacologic properties.

What should I ask about follow-up?

Which clinical outcome matters—ovulation, symptoms or fertility—and how benefit and adverse effects will be checked.

Questions for your clinician

Does the evidence match my condition and this exact product? What risks or interactions matter for me? How would we assess whether it is helping?
