Regarding prostadynia is it curable? and what is the treatment and how long it takes to be cured ? and what is the role of masturbation in treating it ?? and if prostatectomy needed to be done does it affects fertility ?

"Prostodynia" isn't really a condition or disease; it's a symptom (Latin for prostate pain). What treatment will help depends on the cause. If no particular cause can be found, it is unlikely to be dangerous or to lead to serious health problems; it would not affect fertility. It's an issue of comfort, not serious health issues. But make sure you're properly evaluated for possible causes.
