🔥 Libido & Sexual Health

Libido was amazing the first month of TRT but now it’s totally gone?

Asked in r/trt · Answered by the HeydayMD team ·

I felt like a teenager again during the first few weeks of treatment, but now in month two, my sex drive has completely disappeared. My energy is still okay, but the initial boost in desire is totally gone and I'm worried I'm doing something wrong.

The short answer

This 'honeymoon phase' followed by a crash is often caused by the body’s natural testosterone production shutting down while estrogen levels simultaneously begin to climb. When estrogen (estradiol) levels rise too high or fall too low in relation to your new testosterone levels, it can significantly dampen libido and erectile function. At HeydayMD, our clinicians focus on fine-tuning this hormonal balance through frequent lab monitoring and personalized protocol adjustments rather than just chasing a high testosterone number. Managing these fluctuations early on is key to maintaining the long-term benefits of therapy without the roller coaster effect.

Every body is different. A licensed provider can look at your own labs and symptoms.
