Some women can have difficulty producing healthy oocytes. In the past, this was an insurmountable obstacle, but today the problem can be solved relatively easily thanks to modern infertility treatments and egg donation. The donated egg is fertilized in vitro and the embryo is then transferred to the perspective mother.
There are various legal regulations governing egg donation and it’s always important to learn the valid laws in a given country. Egg donation can be anonymous (where the identity of the egg donor is unknown) or non-anonymous (where the child from such an egg has the right to learn about the identity of the donor).
