Is in vitro fertilization not biological?

IVF is the common name for the technique of in vitro fertilization embryo transfer. Generally IVF is a process in which the mother’s egg and father’s sperm are removed and placed in an in vitro culture for about 3-5 days, and the cultured embryo is transferred into the mother’s uterus to develop into a fetus. Therefore, IVF generally has chromosomes from both spouses, so it is wrong to say that IVF is not pro-life. However, in normal work, we also encounter cases like female infertility, exceptionally low or no eggs, or male infertility with no sperm. If donor eggs or donor sperm are used, it is possible that the chromosomes of the infertile patient who uses donor eggs and donor sperm come from a third party.
