I don't think they worded their conclusions succinctly, because it's confusing to read partial loss and total loss in the same sentence. When they say, "...with loss of orgasmic capability in all patients with time.." I interpret that as meaning all of the patients lost the ability to orgasm. Indeed, some of the text in the narrative preceding the conclusions, says, "...Mean time to complete loss of orgasm = 5±2.5 months on ADT, with 12% capable of orgasm within 6 months of starting ADT, 8% 6-12 months and none beyond that time-point."

So again, I read "complete loss of orgasm" and "none beyond that time-point" to mean all patients in the study lost the complete ability to orgasm after about a year and some before that. But I'm not a doctor and I didn't take the ADT. I would hope they did some sort of followup to see if any regained their ability to orgasm when/if they stopped the ADT.

Also, I found some indication that "push button" orgasms has been studied in relation to implanting a device in the body that could trigger orgasm, but it's from many years ago and who knows where it is today. Maybe Elon Musk could figure out the science since he's into brain implants anyway. See https://www.bbc.com/future/article/20140321-orgasms-at-the-push-of-a-button.
