What helps to slow testosterone growth?

Good afternoon, dear friends.

I'm 49 years old. My cancer is genetic (ATM gene mutation).

Three years after diagnosis, initial PSA 530 (Gleason 4+5), three bone metastases, and metastases to the pelvic, cervical, and pulmonary lymph nodes. The prostate is still there, but they didn’t perform surgery on me because the doctor said it was dangerous.

Chemotherapy and ADT (Zoladex 10.8) began in May 2024

I completed eight chemotherapy sessions over six months and Zoladex 10.8 injections. After chemotherapy (October 2024), my testosterone level was 1.1 and has been slowly increasing throughout 2025 despite switching to Diphelerin 3.75. My testosterone level is 1.61 (as of November 2025).

Six months after the double combination of chemotherapy and ADT (Zoladex 10.8), I was given Erleada , start February 2025

My urologist-oncologist isn't alarmed and says everything is fine. He says I can try going back on Zoladex 10.8, but another specialist says I should stay on the medication I take monthly (Diphelerin 3.75). For now, I'm taking it monthly (once every 28 days).

I've heard that testosterone levels should be below 0.7 to minimize risks.

Furthermore, I'm told that if my testosterone levels rise to 1.7, I'll need to have my testicles removed.

PS I've noticed that my testosterone levels have slowed down recently over the past 4 months, reaching 0.06. 1.55 - August 2025, 1.61 - November 2025

Please share any advice or thoughts on what I should do.

1. Continue taking diphereline 3.75
2. Change the ADT drug to a different one
3. Immediately demand removal of my testicles
4. Other options

I've now introduced testosterone-lowering foods into my diet, such as green tea (3 cups a day), mint, and licorice root. I cut out sex completely and started moving less.

I'm terrified of the tests scheduled for mid-January 2026 🙁

Thank you very much, and stay healthy 🙂
