How many children does a sperm donor have?
The number of children a donor is a biological parent of varies since different countries have different regulations regarding the number of children per donor. In Denmark, a sperm donor can contribute to a maximum of 12 different families. Therefore, the donor can help bring more than 12 children into the world if they are born within the same family.
Do sperm donors receive payment?
