Aromatisation is the process where testosterone is converted into oestradiol, a form of oestrogen. This is a natural and essential process in the body, as oestradiol plays an important role in maintaining bone health, mood, and overall well-being in men.
When you’re on testosterone replacement therapy (TRT), this conversion can sometimes lead to higher-than-usual levels of oestradiol. While balance is key—too little oestradiol can cause its own issues—elevated levels may lead to side effects like water retention or mood changes. This is why regular blood tests and monitoring are essential during TRT to ensure your hormone levels remain in the optimal range.
One thing to keep in mind is that TRT can suppress your body’s natural testosterone production. This doesn’t happen overnight and depends on factors like the duration of treatment and the dosage used. For men who have been on TRT long-term, natural testosterone production may not fully recover if treatment is stopped.
For those who have used anabolic steroids (often at very high doses) over extended periods, natural testosterone production can sometimes be permanently affected. This highlights the importance of working with a healthcare professional to manage your hormones safely and responsibly.
