Back in the early 60s I had ambitions to join the Fleet Air Arm and fly Buccaneers. Yeah right, scouser from working class family joining a RN officers' mess!

Ah, well, we can all dream.
Anyway, the bumf I received informed me that the loss of one testicle was not a bar to joining. I'm still not sure why you couldn't join if you'd lost both. But, hey, that was a long time ago. I can't believe you'll have any problem now. After all women join these days and having neither balls nor todgers clearly doesn't affect their ability to do whatever FAA officers do.
And, no, I can't see that RN is any different than RM in this case. But this is all conjecture. Get your ass down to the recruiting office and they'll tell you the score. Your 'condition' is not a medical rarity; 'assymetry' in all sort of organs is fairly common.
[And all the 3 badgers can bog off! You'll obviously be wondering how I can remember this after 40+ years, but I've got both and they're still functional! - It's obviously a deep-seated fear I carry in my 'id'
