Male egg

Male eggs are the currently theoretical result of a process in which the eggs of a female would be emptied of their genetic contents (a technique used in the cloning process), and those contents would be replaced with male DNA. Such eggs could then be fertilized by sperm. The procedure was conceived by Dr. Calum MacKellar, a Scottish bioethicist. With this technique, two males could be the biological parents of a child. However, such a procedure would additionally require an artificial womb or a female gestational carrier.
