| 1 | In RealLife, theoretically it should be possible for two women to have a biological daughter by a process called ''haploidization'', or through [[http://www.sciencedaily.com/releases/2007/04/070412211409.htm creating sperm cells from one of the two mother's bone marrow]]. (But women alone couldn't produce a son, due to the lack of a Y chromosome.) For males, there is research being conducted on the creation of [[http://www.geneticsandsociety.org/article.php?id=3904 male eggs]], which consists of removing the nucleus of an ovum and replacing it with the nucleus of a sperm. This new egg would then be fertilized by sperm from the other father. The process has been documented in mice and its viability in human reproduction is still being developed. It is also theoretically possible to achieve [[MisterSeahorse male pregnancy]] by implanting an embryo in the abdominal cavity, but risk factors make it unlikely that this will be tested. |

| 3 | Alternatively, a same-sex couple where one half is UsefulNotes/{{transgender}} can bear a biological child if the trans partner's genitalia hasn't been altered. While hormone therapy will halt sperm production or ovulation, a trans person who wishes to conceive can temporarily go off the hormones if they so desire, or freeze their gametes before beginning transition. |
