Do You Need HCG With TRT?

HCG is not a mandatory addition to testosterone replacement therapy, according to Doctor O’Connor. Responding to questions about combining the two, he explains that the decision depends on what a man hopes to achieve, rather than a rule that everyone on TRT needs HCG.

Possible reasons for adding HCG include maintaining testicular size, preserving ejaculate volume, and concerns about fertility. Dr. O’Connor describes the supporting fertility evidence as limited and emphasizes that he offers HCG without promising a particular outcome. He also discusses water retention and increased estrogen production as potential drawbacks when HCG stimulates additional testosterone production alongside prescribed testosterone.

The conversation then turns to the practical burden of treatment. Adding HCG to frequent testosterone injections can create a schedule that becomes difficult to maintain over years, even when it initially seems manageable.

Dr. O’Connor argues that testosterone injection frequency should reflect the formulation, individual response, and a sustainable routine. He contrasts the fluctuations associated with widely spaced cypionate or enanthate injections with the longer duration of testosterone undecanoate, and he shares his own regimen as a personal example.

The closing discussion broadens to long-term health, limiting unnecessary androgen exposure, and attitudes toward medication. Dr. O’Connor questions why some men reject prescribed cardiovascular treatments while accepting products labeled “not for human consumption.”
