will puberty blockers affect my erection ?

Dr Camiel does not know of any medical research that supports this. Every part of the world has different standard treatments for hormones. In the Netherlands, where he works, the main blockers are injectables and so they are long-lasting say, for a month or 3 months. This has a lot of effect in completely decreasing your testosterone levels. This is like a sexual nuclear bomb which makes us question if our bodies can work afterwards. There is a pill too which is called adro cure but it has side effects if you use it for your lifetime.
So spironolactone is not a common blocker in the Netherlands. There are a lot of regional and inter-continental differences so there is no consensus on which is the best hormone or which should be recommended to everyone. But it is important to know that these will affect your erections. Some women just want to stick with estrogen and then are feminizing effects. While others go for blockers because they do not like the idea of erections. So hormone care should be personalised because there is no one main route, instead, there are different routes that people can take.
