I am 7 months post-Orchie. The actual surgery is not a big deal, I was up and round in 24 hours. Albeit not doing any lifting at all. I did not get any hot flashes for 3 months, and I was on my HRT.
I have noticed that my breasts are filling out more now. Spironolactone took care of the sexual desire, I had been on it for over a year.
Whoever does your Orchidectomy, make sure that you mention that you might be getting an SRS to minimize scarring. Your feminine side will come to the surface once you begin HRT, if it hasn't already..
