Enclomiphene vs clomiphene (Clomid) for men: the differences

This guide explains the two drugs in plain words, what one clinic study found when men switched, and what to ask a clinician. It is general information, not medical advice.

What each pill is

Clomiphene is a mix of two molecules that are mirror images of each other. One is enclomiphene. The other is zuclomiphene. Both block an estrogen signal in the brain, so the brain tells the testicles to make more testosterone.

Enclomiphene is the first molecule on its own. The idea is that the second one adds side effects without helping. That idea comes from the clinic study below. It has not been proven in large long-term trials.

FDA status of each

Clomiphene has an FDA label. The label says: "Clomiphene citrate is indicated for the treatment of ovulatory dysfunction in women desiring pregnancy" (DailyMed label, read November 14, 2026). Low testosterone in men is not on it. A doctor who prescribes it to a man is using it off label, which is legal and common but not what the label covers.

Enclomiphene has no FDA label. Online programs sell a compounded version, made for each patient by a pharmacy. The FDA says it does not verify the safety, effectiveness or quality of compounded drugs before they are sold (FDA). Our enclomiphene cost guide covers that status in more detail.

What the studies compare

The clearest head-to-head look is a 2024 review of 66 men at one Baylor College of Medicine clinic. Each man took clomiphene first, then enclomiphene. We read the abstract on PubMed, the US National Library of Medicine's research index, on November 14, 2026.

• Testosterone. It rose a median 166 ng/dL on enclomiphene versus 98 on clomiphene. The gap was not statistically firm (P=0.20), so do not read it as a win.
• Estradiol. This is a form of estrogen. It fell on enclomiphene and rose on clomiphene (P=0.001).
• Side effects. "Adverse effects were statistically significantly less frequent with enclomiphene," including lower sex drive, less energy and mood changes (Saffati et al., 2024).

A pooled review of randomized trials, which mixed both drugs, found that the pills raised testosterone more than a dummy pill. Their effect was about the same as testosterone gel (Hohl et al., 2025). Our enclomiphene vs TRT guide covers that comparison.

Where the evidence is thin

The 2024 study looked backward at chart records at one clinic, with no control group. The same men took both drugs in order, so the order may have mattered. The authors say "further research and more extensive studies are warranted." We found no large trial that gave men clomiphene and enclomiphene side by side.

The clomiphene label also lists problems seen in its women's trials. One is vision: "blurring or other visual symptoms such as spots or flashes" may occur. Those findings come from women, not men. They are a reason to tell a clinician about any change in vision.

The label also reports that clomiphene given to male rats "caused decreased fertility." That is an animal finding, and it is a good question for a clinician if keeping fertility is your goal.

What online programs sell

Most programs we track list enclomiphene. Maximus, TRT Nation, Hims, PeterMD, Taurus Meds, HealthRX and Hone Health all show a price on their pages, dated on our enclomiphene price table.

Male Excel lists clomiphene on its own page, titled "Buy Clomid for Men Online - Clomiphene Citrate" (read November 14, 2026, maleexcel.com). It does not print a clomiphene price there, so check the page for the current figure. Male Excel also sells a combination pill that contains enclomiphene plus two other ingredients.

The partner option for the closest product is the enclomiphene row at the top of our price table. Plans differ on blood tests and memberships, so look at what each price includes.

What to ask a clinician

1. Which of the two would you prescribe me, and why?
2. If compounded, which pharmacy makes it?
3. Which blood tests do I need first, and when are they repeated?
4. What should I do if my vision or mood changes?
5. How long before we review whether it works?

FAQ

Enclomiphene vs clomiphene (Clomid): what is the difference?

Clomiphene is a mix of two molecules, and enclomiphene is one of them. Clomiphene is FDA-approved for women's ovulation and used off label in men. Enclomiphene has no FDA approval. One clinic study of 66 men found fewer side effects after the switch to enclomiphene, and more research is needed.

Is enclomiphene better than Clomid for men?

The evidence is limited. A 2024 chart review at one clinic found fewer side effects on enclomiphene, and testosterone rose by a similar amount. No large trial has put the two side by side. A clinician can weigh your history, fertility goals and what each program sells.

Can men take Clomid for low testosterone?

Doctors prescribe it off label, which means for a use not on the FDA label. The label covers ovulation in women. A clinician should check your blood tests first and review them again. Online programs that offer it are listed on their own pages.

Is clomiphene cheaper than enclomiphene?

Clomiphene is a generic drug with several makers. Programs rarely print a clomiphene price, so we cannot give one. Enclomiphene is listed from $98 a month on a prepaid plan, with higher month-to-month prices. Compare on the price table.

Does enclomiphene or clomiphene protect fertility?

Both aim to keep the testicles working, unlike testosterone, which can lower sperm production. In a 16-week trial, enclomiphene kept sperm concentration in the normal range (Kim et al., 2016). Ask a clinician if fertility is your goal.
