What did @jddenhamfit actually say?
The creator claims he fathered two children while staying on testosterone replacement therapy, contradicting doctors who told him he had to stop. His method: adding HCG on Monday, Wednesday, Friday at "higher doses" alongside continued TRT. He is direct that he is not a doctor, that he cannot prescribe a protocol, and that results are not guaranteed. To his credit, he says repeatedly, "do the research" and "seek a doctor's help."
The core claim is that TRT does not automatically mean infertility, and that HCG can preserve or restore sperm production even while exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis. That is a real, clinically recognized strategy. The vagueness around dosing is frustrating but, given the platform and his non-clinician status, it is probably the responsible choice.
Does the science back this up?
Yes, with important caveats. Exogenous testosterone suppresses luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn shuts down intratesticular testosterone production and spermatogenesis. HCG mimics LH and directly stimulates testicular Leydig cells, maintaining intratesticular testosterone and, to a degree, sperm output.
Hsieh et al. (2013, Fertility and Sterility) studied 26 men on TRT who wanted to conceive. After adding HCG, 87 percent showed improved sperm counts and 55 percent achieved pregnancy. A review by Ramasamy et al. (2014, Urology) confirmed that HCG co-treatment can maintain spermatogenesis during testosterone therapy in a meaningful subset of men, though success is not universal. The evidence is not from massive randomized controlled trials, so certainty has limits. But the biological mechanism is sound and clinical use is well established.
What did they get wrong (or right)?
He got the main concept right. HCG co-therapy with TRT is a legitimate, evidence-supported fertility preservation strategy. That is not fringe. It is used regularly by reproductive endocrinologists and urologists who specialize in male fertility.
What he got wrong is the implied simplicity. Saying "hint, hint, HCG Monday, Wednesday, Friday" makes it sound like a reliable shortcut. For some men, it will not work at all. Severe primary testicular failure, long-duration TRT, or low baseline sperm counts can all limit HCG's effectiveness. The creator also never mentions FSH, which matters because HCG primarily drives Leydig cell function, not Sertoli cell support of sperm maturation. Some protocols add FSH or clomiphene for men who do not respond to HCG alone (Wenker et al., 2015, Journal of Sexual Medicine). Leaving that out is an omission, not a lie, but it matters for the men this video reaches.
What should you actually know?
If you are on TRT and want to conceive, you have real options and you should not accept "come off testosterone" as the only answer without a conversation with a reproductive urologist or endocrinologist. That part, @jddenhamfit gets right.
What a proper clinical workup actually looks like: a baseline semen analysis before adding anything, monitoring intratesticular testosterone and sperm counts over time on HCG co-therapy, and adjusting if HCG alone is insufficient. The window matters too. Men who have been on TRT for years may take six to eighteen months of HCG co-therapy before sperm production recovers meaningfully (Liu et al., 2002, Journal of Clinical Endocrinology and Metabolism).
- HCG is a prescription medication. You need a licensed provider to obtain and use it legally in the US.
- Compounded HCG and brand-name HCG are not interchangeable without clinical guidance.
- This strategy does not work for everyone. Have realistic expectations.
- Do not adjust TRT or add HCG based on a TikTok video. Get a semen analysis first.
