TRT vs. enclomiphene: a plain-English comparison

If your testosterone has come back low and your provider has confirmed you're a candidate for treatment, the next question is usually: which treatment? The two main options are testosterone replacement therapy (TRT) and enclomiphene. They sound similar. They aren't. Here's how they differ in plain English.

TRT: replacing the hormone directly

TRT does exactly what it sounds like. You add testosterone to your system — typically as a weekly or twice-weekly injection, sometimes as a cream or pellet. Your body's testosterone level rises within days, and most patients feel meaningful improvements in energy, libido, mood, and recovery within four to eight weeks.

The tradeoff: when you add testosterone from outside, your body's own production shuts down. Your brain stops sending the signal to your testes to make more. That has a few consequences worth knowing about.

• Your testes typically shrink somewhat over time.
• Sperm production usually drops sharply, which is a problem if you want kids.
• Coming off TRT is non-trivial — your natural production doesn't snap back overnight.
• You'll need periodic blood work to monitor red blood cell count, estradiol, and a few other markers.

Enclomiphene: stimulating your own production

Enclomiphene takes a completely different approach. Instead of giving you testosterone, it tells your brain to keep sending the 'make more' signal, by blocking the negative feedback loop estrogen creates. The result: your own testes ramp up production.

Because the hormone is still coming from your own body, enclomiphene preserves fertility — sperm production keeps running normally. It's an oral medication (a pill, not an injection), and it's generally well tolerated.

The tradeoff: response varies. Some men get a large, durable T increase. Others get a smaller bump than they'd see on TRT. And it only works if your testes are still capable of producing testosterone in the first place — if your low T is rooted in testicular failure, enclomiphene can't help.

Fertility is usually the deciding factor. If having children — now or later — is on the table, that conversation happens before anything else.

Side effects, briefly

TRT's most common side effects are increased red blood cells (manageable with monitoring), acne, water retention, and occasional mood swings during dose changes. Enclomiphene's are usually milder: occasional headaches, mood changes, and rare visual disturbances at high doses.

Cost and convenience

Enclomiphene is a pill, taken daily. TRT is an injection, usually weekly. Both are reasonably affordable through NowYou; injections require a small skill that takes about ten minutes to learn and becomes routine within a few weeks.

How most men decide

• Want to preserve fertility, prefer a pill, OK with a possibly smaller boost: enclomiphene.
• Done having kids (or fertility isn't a priority), want maximum and reliable T increase: TRT.
• Younger patients with mildly low T: enclomiphene is often the first try.
• Older patients or significantly suppressed levels: TRT is often the better tool.

What happens at NowYou

After your intake and labs, a licensed provider walks through the tradeoffs with your specific numbers and your specific goals. There's no one-size-fits-all answer here. Treatment is then shipped to your door, and follow-up labs are part of the program — not an upsell.

If you haven't done labs yet, that's the place to start. Treatment decisions without data are guesses.
