Overview
The evidence base for HCG (human chorionic gonadotropin) can span preclinical work, early human data, and—where applicable—larger clinical trials. The strength and maturity of that evidence determine how confidently clinicians and researchers talk about its effects.
Key evidence themes
- Preclinical models exploring mechanisms and proof-of-concept.
- Early human or pilot data, if available.
- Larger controlled trials for molecules with formal indications.
Context and caveats
When reviewing literature on HCG (human chorionic gonadotropin), it is important to consider study design, endpoints, sample size, and duration, as well as how closely study populations match real-world use. Marketing narratives frequently move faster than rigorous evidence.
Sport & Anti-Doping Warning
Human chorionic gonadotropin (hCG) has been misused by male athletes as part of steroid cycles to stimulate endogenous testosterone and is specifically prohibited in male competitors.

In anti-doping rules, hCG is banned in males and often treated as a marker of attempted steroid cycle manipulation rather than a benign fertility drug.
