Did GG have a sperm donor?

I'm curious, was there a sperm donor involved in the conception of GG? This question arises because in today's world, assisted reproductive technology has become increasingly common, and it's not uncommon for individuals or couples to seek the help of sperm donors to expand their families. So, is it possible that GG was conceived with the aid of a sperm donor, or was there a different method of conception used? It's a valid inquiry, especially if one wants to understand the full story behind GG's origins.
