Male egg

Male eggs are the result of a process in which the eggs of a female would be emptied of their genetic contents (a technique similar to that 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.[1][2][3][4][5][6]

In 2003, researcher Hans Robert Schöler at the University Of Pennsylvania successfully created eggs using both male and female mouse DNA. [7]

Same-sex couples

Today two males can both be parents to their child, although this is not legal in most jurisdictions. Potential changes to this legal position in the near future, together with the recent advances in the technology behind artificial uteruses, it might be possible for two males to have children together without a surrogate mother being involved.
