I guess for me it would depend on what "pretty spooked" means. If she was just sort of quietly avoiding paying much attention to you guys, I wouldn't be too worried, although it may be a sign that she hasn't had much socialization. If she was cowering and actively fearful, I'd be more concerned that she may have a weak temperament--but again, it could also be a sign that the breeder just didn't have much time to work with her and she's never learned to be comfortable around new people. How does she react to new situations, other dogs, people you pass on walks, etc. now that she's used to you?
As far as your fiance, a lot of dogs are afraid of men because of their generally bigger builds, deeper voices, etc. A lot of men have also been socialized to have more assertive or even aggressive body language when compared to women, which may also scare nervous dogs.
I agree that going to positive training classes will be a great thing for building a relationship between your dog and your fiance. He should strive to be 100% positive at this point. Clicker training is fantastic for this.
At home, he should mostly ignore her but always have treats on him. If she approaches him, he should give her a treat without looking at her. If she's even in his general vicinity, he should toss her treats without looking at her. Basically, teach her that he's not going to do anything that could even remotely be interpreted as threatening, and he is also a walking treat dispenser. He's 100% good things, not scary! Getting down on her level is a good thing, as long as he's not staring at her while he does it. When I took in dogs who were afraid of men, I would have my ex sit on the floor while we watched TV and toss treats to the dog while otherwise ignoring it, just to give an actual example of what I mean.
By the same token, he should not be leashing her right now. If she's comfortable once she gets out of the house walking with him, then he can walk her after you leash her--but again, he should be ignoring her except to do positive training (easiest way is to always have a treat in his hand, and when she approaches, give it to her). Personally, I think getting out and moving together while ignoring each other is great for helping the dog feel comfortable with someone. However, if she's really fearful, being leashed to him and put in new situations with him may just reinforce that, so if that is the case, you should probably be the one walking her for the time being.
I also think he should handle her feeding, although he should do so by setting her bowl down and then walking away to a distance where she feels comfortable. If he can be in the room, great, but he may have to leave if she's really fearful. Again, he should be sure not to look at her too much and especially not to stare at her while she's eating.
Basically, his rule of thumb should be to mostly ignore her, but reward her as often as she'll let him. Reassure him that this is actually a fairly common problem with puppies, rescue dogs, and undersocialized dogs (at least in my experience). 11 months old is old for it to still be happening with a pup, but as I said it could be that she has just not really been around men (or men like your fiance) before. It is nothing personal and many, if not most dogs get over it fairly quickly as long as you don't force it and accidentally reinforce her fear.
