Testosterone plays a vital role in nearly every aspect of men’s health - from sexual function and mood regulation to energy levels. It also influences how the body distributes and stores fat, which often shows up as visible symptoms of low testosterone, such as weight gain and fatigue. When testosterone levels drop, these physical manifestations can significantly impact quality of life.
When testosterone levels fall too low, resulting in a problem known as low testosterone or male hypogonadism, it can lead to noticeable changes.
Traditional options like testosterone replacement therapy (TRT) have been around for decades, but they may not work for everyone. When you take testosterone from an outside source (like injections or gels), it can send a signal to your brain to stop making its own.
Over time, this can lower sperm production and lead to fertility problems. Because TRT delivers testosterone from an external source (such as injections, gels, or patches), it can reduce the body’s own production. This happens because the brain senses there’s already enough testosterone in the system and stops sending the signals needed to stimulate natural production.
Importantly, TRT doesn’t cause hypogonadism; it addresses it. But if TRT is stopped, testosterone levels usually fall again because the underlying issue (hypogonadism) remains.
The good news is that treatments like enclomiphene citrate provide an alternative. Instead of supplying testosterone directly, enclomiphene stimulates the brain to signal the testes to produce more testosterone naturally. This approach can help restore hormone balance while maintaining sperm production and supporting fertility.
Understanding the distinction between primary hypogonadism and secondary forms of testosterone deficiency can give you a helpful introduction to enclomiphene.
The testicles produce 95% of the testosterone levels in the average male. In primary male hypogonadism, the testes don’t produce enough testosterone, even when they receive signals from the brain.
In secondary hypogonadism, the process starts higher up in the body. It involves the brain’s hormone control centers (the hypothalamus and the pituitary gland), which regulate the signals that tell the testes how much testosterone to make.
Think of these areas like the main control panel for testosterone levels. They produce hormones called luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones act as messengers, telling the testes to make both testosterone and sperm.
When the system is disrupted by health conditions such as obesity or certain medications, testosterone levels drop. Yet the testes still can function if they are stimulated properly.
That’s why men with secondary hypogonadism are excellent candidates for treatments that encourage natural testosterone production rather than simply replacing testosterone externally.
Enclomiphene citrate is known as a selective estrogen receptor modulator (SERM). Another selective estrogen receptor modulator is clomiphene citrate, which doctors have been prescribing for years to help treat male and female infertility.
But enclomiphene therapy is a more targeted option that acts as an estrogen receptor antagonist, blocking estrogen receptors, mainly in the hypothalamus and pituitary gland.
When enclomiphene blocks estrogen receptors, the brain receives the message that estrogen has dropped. In response, it starts sending out more LH and FSH.
These hormones travel to the testicles, telling them to step up testosterone and sperm production. That’s a big difference compared to using testosterone creams or injections, which can override your body’s hormone-making ability.
Many men who’ve tried enclomiphene citrate have seen their testosterone rise back into the normal range. Along with that, symptoms like low energy, fatigue, and decreased libido often start to improve.

You might be wondering, why not just stick with clomiphene citrate?
The catch is that clomiphene citrate is a mix of two different components, called isomers. One part, enclomiphene, is the helpful piece that blocks estrogen receptors. But the other part, zuclomiphene, acts more like estrogen in the body. That can sometimes cause side effects men don’t want, like hot flashes, mood swings, or breast tenderness.
By using only the enclomiphene portion, enclomiphene citrate delivers a more straightforward effect. It helps raise testosterone in a predictable way, without as many unwanted side effects.
Some endocrinologists prefer enclomiphene because it raises serum testosterone without the estrogenic influence. Enclomiphene supports sperm production and also supports sperm counts, making it a promising alternative to both clomiphene citrate and traditional testosterone replacement therapy (TRT).

When considering treatment options for low testosterone, it’s important to look beyond lab numbers and think about the impact on your quality of life. For men with secondary hypogonadism, the benefits of enclomiphene often include:
Enclomiphene increases endogenous testosterone production and maintains hormonal communication between the brain and testes. That makes enclomiphene a major advantage if you want to feel normal and maintain reproductive health.

Most patients start with 12.5–25 mg of enclomiphene citrate taken once daily by mouth. It is absorbed quickly, reaching peak levels within a few hours, and has a half-life of approximately 10 hours. You typically won’t need injections or topical applications to increase testosterone levels when taking enclomiphene citrate.
Most men notice the benefits of enclomiphene therapy two to four weeks after starting treatment. You may notice increased energy and a better mood first, followed by improvements in libido and body composition over the next couple of months.
It’s important to monitor your progress during treatment. Your doctor will check your hormone levels regularly (like testosterone, estradiol, LH, and FSH) to see how your body is responding. They’ll also watch for any side effects, though most men find that enclomiphene doesn’t cause many problems and is generally easy to tolerate.

Another reason more men are interested in enclomiphene is how it can help protect fertility. Unlike standard testosterone therapy, which often lowers sperm counts, enclomiphene encourages the body to keep making sperm while raising testosterone. Because it stimulates follicle-stimulating hormone, it can maintain or improve sperm counts and semen quality, making it a viable option to treat male hypogonadism. That makes enclomiphene ideal for younger men who hope to start or grow a family.
Compare this with exogenous testosterone, which often lowers FSH to undetectable levels and halts sperm production. Some men who switch from testosterone injections to enclomiphene see a rebound in sperm concentration over several months, improving their chances of conception.

Enclomiphene isn’t right for everyone. If you have primary hypogonadism, meaning your testes can’t produce testosterone even with stimulation, this therapy may not help. It also isn’t approved in every country, although doctors can often prescribe it off-label.
That said, for secondary hypogonadism, enclomiphene offers a practical, fertility-friendly alternative to TRT. If you’ve been reluctant to start testosterone replacement because of fertility risks, enclomiphene is worth discussing with your physician.
Low testosterone can take a real toll on a man’s life, from sexual dysfunction to mood changes. For decades, the only real choice was testosterone replacement therapy, but today, enclomiphene citrate provides an alternative option for many men.
By encouraging the brain to produce more luteinizing hormone and follicle-stimulating hormone, enclomiphene restores natural testosterone production without shutting down sperm production. It has fewer side effects than clomiphene and helps maintain fertility.
If you’re experiencing symptoms of testosterone deficiency, talk to your healthcare provider about whether enclomiphene treatment could be right for you. With the right plan, it’s possible to feel like yourself again while minimizing any potential adverse effects.
