Eli Y. Adashi & I. Glenn Cohen, Assisted Same-Sex Reproduction: The Promise of Haploid Stem Cells?, Stem Cells & Dev. (Oct. 19, 2020).

Abstract: Same-sex couples, not unlike their heterosexual counterparts, would prefer having a genetically related child.However, assisted same-sex human reproduction has heretofore been deemed infeasible absent haploid cellularanalogs of human gametes. Recent developments, however, may have overcome this limitation through thederivation of haploid embryonic stem cells (hapESCs). Undifferentiated, pluripotent, self-renewing, and stablyhaploid, hESCs have also displayed germline competence. It is in this capacity that murine hESCs, doubling upas de facto gametes, gave rise to bimaternal and bipaternal progeny. Herein we argue that assisted same-sexhuman reproduction, although potentially attainable at this time, is still years away from the clinic. In support ofthis perspective, we note the significant technical, regulatory, statutory, and societal hurdles that stand in theway of near-term implementation.
