TRT fertility claims from @kruckemonster2, fact-checked

What did @kruckemonster2 actually say?

The creator claimed he fathered a child while on TRT, saying he "got a baby doing four months." He listed fertility-preserving options he said can be used alongside testosterone: zinc, glutathione, HCG, clomid, and enclomiphene. His bottom line was that "TRT doesn't have to mean infertility," and he directed viewers to DM for doctor consultations.

To be clear about what this video is: it is a promotional clip for a gym-based telehealth service in Fresno, California. That context matters when evaluating how the information is framed and what's left out. The creator is not a clinician, and the video runs about 20 seconds. That's a lot of medical nuance to compress into a gym ad.

Does the science back this up?

On the core claim, yes, with significant caveats. Exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis, which reduces or eliminates sperm production in most men. But fertility is not always permanently lost, and co-treatments can preserve it.

HCG (human chorionic gonadotropin) mimics luteinizing hormone and can maintain intratesticular testosterone production and spermatogenesis during TRT. A 2013 study by Hsieh, Bhardwaj, and Lipshultz published in the Journal of Urology found that HCG co-administration preserved semen parameters in hypogonadal men on testosterone therapy. Enclomiphene and clomiphene citrate work differently, stimulating the pituitary rather than bypassing it, and have shown promise in maintaining fertility signals. A 2016 paper by Kaminetsky et al. in the Journal of Sexual Medicine supported enclomiphene as an option for men wanting to maintain sperm production while addressing low testosterone.

So the claim that fertility-preserving options exist alongside TRT is grounded in real evidence. The problem is the list he gave.

What did they get wrong (or right)?

HCG, clomid, and enclomiphene belong on that list. The evidence supports them. Zinc is a stretch, and glutathione is a real problem.

Zinc deficiency is associated with lower testosterone and impaired sperm quality, and correcting a deficiency can help. But zinc supplementation in men who are not deficient has weak evidence for meaningful fertility benefit. Presenting it alongside prescription medications as a parallel fertility-preserving strategy overstates what the research shows.

Glutathione is where this gets genuinely misleading. Some small studies have looked at antioxidant therapy for male infertility, but glutathione does not have established clinical evidence as a fertility-preservation strategy specifically during TRT. Grouping it with HCG and enclomiphene implies equivalent clinical standing. It does not have that. A 2019 Cochrane review on antioxidants for male subfertility (Smits et al.) found the overall evidence quality was low and results inconsistent.

The creator also mispronounces enclomiphene as "enclomaphine," which is minor but worth noting given the medical context. More importantly, the video mentions "ACG" rather than HCG, which may be a slip but could confuse viewers searching for information.

What should you actually know?

TRT-induced suppression of sperm production is real, common, and sometimes severe. A 2011 review by Nieschlag in the journal Andrologia confirmed that testosterone acts as a contraceptive in many men precisely because it shuts down spermatogenesis. Recovery after stopping TRT is possible but not guaranteed and can take months to years.

If fertility matters to you and you are considering TRT, you should be talking to a urologist or reproductive endocrinologist, not just a general telehealth provider at a gym. Sperm banking before starting TRT is the most straightforward insurance policy and is rarely discussed in content like this.

HCG co-therapy is a legitimate conversation to have with a qualified physician. So is clomiphene or enclomiphene, though these are typically used as alternatives to TRT rather than alongside it in fertility-focused cases. The clinical picture is more complicated than a 20-second video can capture.

One man fathering a child while on TRT, as the creator claims, is an anecdote. It is not a framework for your reproductive planning. Sperm suppression on TRT is dose-dependent and individual. Some men maintain some sperm production; many do not. Do not assume you are the exception.
