Yes, they will. Testicles are suppressed by taking any kind of testosterone and they will not make as much testosterone while the pellets are working. This is not permanent and the testicle retains its ability to produce testosterone.
Testosterone pellets will make it better, if you do not convert it to DHT; we will treat that if it happens.
Your blood levels of estrogen and DHT are checked after treatment to see if they are elevated. Some men still convert to these metabolites even on testosterone pellets. If they are converting, we troubleshoot with natural supplements such as DIM and Saw Palmetto, or an aromatase inhibitor prescription.
No. Metabolites of testosterone, Dihydrotestosterone and estrogen cause prostate enlargement and contribute to prostate cancer. Estrogen increases and testosterone decreases as men age and as men gain belly fat. Testosterone pellets are the only replacement that reverses that trend.
