Glad to hear your surgery went well.
Does not help your situation of having to deal with low T.
Healthy testosterone levels are critical to men's health/overall well-being.
Although the use of PDE5i will enhance/improve erectile function underlying vascular health is critical let alone healthy T levels are needed to experience the full beneficial effects.
Testosterone and more importantly its metabolites estradiol and DHT are critical not only for libido/erectile function but overall health (brain, cardiovascular, bone, metabolic, immune system, body composition).
