Unfortunately, no, she (he?) won't produce sperm because you need testicles to do that, and I'm pretty sure they haven't figured out a way to transplant those...

For both Male-to-Female's and Female-to-Male's, the process of transition (taking hormones, etc) makes you sterile. Also, while the medical technology is able to produce wonderful results for Male-to-Female's (creation of a vagina), our FTM brothers are not so lucky because the results are not as promising (I've heard a procedure which gives a mechanical pump thing that looks like a penis...

). As far as I know, many FTM's don't have genital surgery.

okay, so my sister wants to get a sex change because she's never felt right in her own body
There's more to transition than just the surgery. Gender transition is a serious live-altering journey. I would recommend that your sister seek a counselor who has experience with gender issues.
