Hormonal action and testicular function
hCG is naturally produced by the placenta during pregnancy, where it helps maintain the corpus luteum. Its LH-like activity also explains its role in the production of sex hormones in the gonads.
In men, direct stimulation of testicular receptors occurs even when the LH signal is reduced. In medicine, this property is used in certain forms of hormonal deficiency and infertility of hormonal origin.
Fertility and context after a cycle
- Male fertility: treatment aims to restore a hormonal environment conducive to reproductive function. The choice of treatment depends on the cause of the disorder and the fertility assessment.
- After steroid use: monitoring distinguishes between the testicular response to hCG and the autonomous recovery of the hormonal axis. An increase in testosterone during treatment is not sufficient to establish this recovery.
- Body composition and recovery: results depend on the initial hormonal deficiency, training, and diet. The specific benefits of hCG on muscle preservation during a cutting phase remain to be established.

The dose, duration and methods of stopping are defined with a doctor based on the hormonal assessment and the response to treatment.
Tolerance and monitoring
Increased testosterone production also increases the amount available for conversion to estrogen. Effects to watch for include gynecomastia, mood swings, and water retention, especially at higher doses.
Reported side effects include pain, redness or swelling at the injection site, headache, fatigue, drowsiness, and edema. Prolonged use or high doses require appropriate hormonal monitoring.
A skin rash, itching, or dizziness may indicate an allergic reaction. Facial swelling or difficulty breathing requires urgent medical attention.
