Science of Same Sex Procreation

Same sex procreation is safest and most likely when it comes as close to existing human reproductive processes which rely on sperm and eggs. This suggests two new medical pathways, female sperm and male eggs. While a bit of information is provided on human male eggs, it is questionable if a viable human egg can exist with an X and Y chromosome - i.e., do human eggs need two X chromosomes to function? Female sperm is a more likely prospect, because men already have sperm with either an X or Y chromosome. Female sperm then requires incorporating a woman's X chromosome into the body of a sperm.

The following animations will help you understand the basic processes for making sperm (spermatogenesis) and eggs (oogenesis) in humans. Two important sub-processes are the two main forms of cellular division: mitosis and meiosis. In the animations that follow, spermatogonia are male diploid germ cells that are used in the first step of making male sperm. Creating a female diploid germ cell in a male-like condition is the first step in creating female sperm.
