Solution:
It still performs excretion such as sweating and respiratory metabolism. Whether it can poo is egestion, not excretion.
It can clone itself without a female if technology permits. Since its cells will still perform mitosis, he is still reproducing. Whether it can lay egg or sperms is sexual matter unrelated to asexual reproduction.
