What did @kmartfit actually say?
The creator claims that TRT will not permanently kill your fertility, as long as your doctor adds HCG or "an inclomethine" (he means enclomiphene, a selective estrogen receptor modulator) to your protocol. He says he has been on TRT for five years and remains "fully fertile" because of enclomiphene. He then pitches a referral to his personal doctor in the comments.
The fertility preservation claim is worth taking seriously. The doctor referral pitch, however, is a different story and deserves its own scrutiny. These are two separate things and conflating them is part of what makes this video slippery.
Does the science back this up?
Partially, yes. The core claim that fertility can often be preserved or restored during TRT is supported by clinical evidence, but the phrase "keeps your fertility at 100%" is not something any honest doctor would promise a patient.
Exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis, sharply reducing LH and FSH. Without those signals, the testes stop producing sperm. HCG mimics LH and can maintain intratesticular testosterone and spermatogenesis during TRT. A 2005 study by Coviello et al. in the Journal of Clinical Endocrinology and Metabolism showed that low-dose HCG (125-500 IU every other day) maintained intratesticular testosterone in men on exogenous testosterone. Enclomiphene, which blocks estrogen receptors in the hypothalamus, can stimulate endogenous LH and FSH production. A 2013 randomized trial by Kim et al. in BJU International found enclomiphene raised testosterone and gonadotropins in hypogonadal men without suppressing sperm production. So the tools he describes are real. The "100%" guarantee is not.
What did they get wrong (or right)?
He got the general concept right: adjunct therapy with HCG or enclomiphene is a legitimate strategy used by reproductive endocrinologists and urologists to preserve fertility in men on TRT. That is not fringe advice. It is in clinical practice guidelines.
What he got wrong is the certainty. Saying these treatments keep fertility "at 100%" is misleading. Response to HCG and enclomiphene varies significantly between individuals. Some men experience incomplete spermatogenesis recovery even with adjunct therapy, particularly after prolonged TRT use. A 2020 review by Patel et al. in Therapeutic Advances in Urology noted that recovery of spermatogenesis is not guaranteed and can take 12 to 24 months after stopping TRT even with assisted recovery protocols.
He also mispronounces and misspells "enclomiphene" as "inclomethine," which is a small thing but matters when 69,000 people are watching and might search that term. More concerning is the comment-section doctor referral. That structure, where a creator funnels followers to a specific provider for commission or affiliation, raises real questions about conflicts of interest that viewers deserve to know about.
What should you actually know?
If you are on TRT and want biological children, this is a real conversation to have with a urologist or reproductive endocrinologist before you start treatment, not after. HCG co-administration and enclomiphene are both used clinically to preserve sperm production, but neither is a guaranteed solution for every man.
- HCG maintains intratesticular testosterone and has the strongest evidence base for fertility preservation during TRT.
- Enclomiphene (not "inclomethine") is an active isomer of clomiphene citrate and can stimulate the HPG axis without direct testosterone administration, making it an alternative to TRT for some men who want to preserve fertility entirely.
- Men who have used TRT for years without fertility preservation may face longer or incomplete recovery windows.
- Sperm banking before starting TRT is the most reliable insurance policy for men who want biological children in the future.
- Any provider recommending a specific protocol should be disclosing financial relationships with the platforms or doctors they refer to.
Bottom line
The creator is not wrong that fertility preservation during TRT is achievable for many men with the right protocol. The problem is the absolute confidence, the sloppy drug name, and the referral funnel. Use this video as a starting point for a real conversation with a licensed provider, not as a treatment plan.
