[X-Men] Could Mystique change to a man, freeze her own sperm and then inseminate herself with it?

Not in canon, *however* Chris Claremont in fact planned this exact scenario to have been how Nightcrawler was conceived-although instead of impregnating herself, it'd have been Destiny, her lover. Marvel said lol fuck no because it was the goddamn eighties, so it didn't make it to text and Azael was revealed to be Nightcrawler's dad. 

Take the validity of that information with regards to canon as you will.
