Testosterone replacement therapy: Head-to-head comparison

After patients have decided to start Testosterone replacement therapy via intramuscular injection route, then we go through this question “Which testosterone formula is suitable for individuals?” Today we will compare between 2 intramuscular injection preparation, Testosterone enanthate & Testosterone undecanoate.

Sexual behaviors parameters which show the improvement

1. Sexual visualization
2. Sexual desirable
3. Sexual satisfaction
4. Numbers of ejaculations per week
5. Number of erections per week
6. Number of morning erections per week

General well-being parameters which show the improvement

1. More focusing
2. Agitating
3. Self-confidence
