(Wrong section
)
Dryson, I'm wondering what you're basing your assertion on? The only evidence I've found in the books has pointed towards normal reproduction. Although female Orcs are not mentioned, it doesn't mean they don't exist. In fact,
Dwarf women were very nearly not mentioned at all, but we know they exist.
Orcs are accepted to be Elves who were captured and corrupted shortly after their "awakening". So says the Silmarillion.
