It's not physically possible for Argonians to reproduce with any other species than Argonians. The females lay eggs, which are then fertilized by the males. Like a human wouldn't be able to fertilize a chicken egg, other races in the TES world simply lack the parts necessary to lay or fertilize Argonian eggs. Men/Mer with Khajiit and vice versa? Maybe, since they reproduce vivipariously. But Argonians with Man or Mer is not possible.
