TRT vs Enclomiphene
Two ways to raise testosterone that differ in one critical way: what they do to your fertility. Here is how they compare so you and your provider can choose.

| Factor | TRT | Enclomiphene |
|---|---|---|
| What it is | Bioidentical testosterone delivered directly | Oral selective estrogen receptor modulator |
| How it raises T | Adds testosterone from outside the body | Prompts your body to make more of its own |
| Fertility | Suppresses natural sperm production | Preserves sperm production and fertility |
| Route | Injection (or other forms) | Daily oral capsule |
| At A2Z | $149/mo — the core program | Separate standalone product, priced separately |
The fertility question
This is the decision. Direct testosterone therapy signals the body to stop its own production, which reduces sperm production. Enclomiphene works upstream — it blocks estrogen's feedback at the pituitary, raising luteinizing hormone (LH) and follicle-stimulating hormone (FSH) so your testes produce more natural testosterone while preserving sperm production. For a man who wants children now or in the future, that difference is often the deciding factor.
When each makes sense
TRT is the stronger, more direct lever and is the right choice for many men whose family is complete. Enclomiphene is the right choice for men who want to raise testosterone while keeping the door open to fertility, or who prefer an oral option. Some men use hCG alongside TRT to preserve fertility pathways — see our TRT and fertility page for that approach. The choice depends on your labs, your goals, and your family plans — your provider helps you decide.
Monitoring
Both require baseline and follow-up labs. TRT monitoring includes hematocrit — the American Urological Association's Testosterone Deficiency Guideline (Statement 11) directs clinicians to measure hemoglobin and hematocrit before and during treatment — plus estradiol and PSA for men over 40. Enclomiphene monitoring adds LH and FSH to confirm the pituitary response. See safety and monitoring for the full panel.
