This is an interesting overview of relevant research: www.bionews.org.uk/page_144104
Some quotes:
"A US study of 40 gay-father families created through (predominantly gestational) surrogacy, and 55 lesbian-mother families created through donor insemination, found that 60 percent of the men's children were boys and 40 percent were girls, while the children born to women were 50.9 percent boys, 49.1 percent girls (Blake et al. 2016; Golombok et al. 2017:6). The sample is not large enough to be conclusive, but together with the memoirs [referred to earlier in this article], it does raise the question of whether sex selection for boys is taking place among gay men who choose gestational surrogacy. "
"Other evidence suggests that in Europe and the US, SSS [social sex selection] is used most often to produce boys (Lemke and Rüppel 2019:89, Sharp et al. 2010). The Gallup polls indicate male preference is predominant among would-be American fathers and has changed very little over the past 78 years. In 2018, 43 percent of the men surveyed said they would want a son compared to 24 percent who opted for a daughter (Newport 2018). Women responding to the Gallup poll have consistently shown no preference. "
The author discusses possible reasons ('replication' of the parents; choosing traits that will help the child 'succeed') but does not address the possibility that the apparent skew by men toward choosing boys over girls could be down to old fashioned misogyny. Interesting omission. Interesting stats.
