Talk:Human sex ratio

Effects of gestation environment
Cite 25 appears to be inconsistent whether malnutrition or obesity lowers the male/female birth ratio. It states:

"Short maternal stature and obesity were independently related to a low sex ratio at birth." and also "These results are consistent with animal experiments that indicate an adverse effect of maternal malnutrition on male fetuses."

Sex ratio < 1 ?
This article mentions the consequences of a high sex ratio, but what about a society or country with a low sex ratio, which is the case for many countries in the Americas, Europe, North Asia, etc? A female majority might have consequences, such as the effect of rejection of a candidate by women in an election, which was proeminent in Brazil's 2018 presidential election, when winning candidate Jair Bolsonaro had to improve his image among women, which was tarnished by his past comments on women, as in Brazil women are the majority of the population and of the electorate.

Not entirely sure intersex belongs here
Seriously why is it that I keep seeing articles on sex and gender someone keeps trying to put intersex somewhere. Like what does intersex have to do with sex ratios? CycoMa (talk) 08:54, 21 May 2021 (UTC)

Just to make sure people are aware humans are a gonochoric species gonochorism literally means a species has either males or females. End of story, it’s just bizarre that this has to be a controversial view these days. CycoMa (talk) 09:02, 21 May 2021 (UTC)

The reason that intersex needs to be discussed in this context seems pretty clear to me: intersex people, by definition, are not unambiguously male or female, so you need to decide how to treat them when estimating a sex ratio. One could conceivably try to reclassify all intersex cases as male or female, count them separately, or just remove them from the total. I don't think it's obvious how to deal with these issues. —Kodiologist (t) 21:02, 25 October 2022 (UTC)


 * At birth, there are such exceptions as XX male syndrome and XY gonadal dysgenesis, from 1 in every 20,000 to 1 in every 100,000. This makes 0,005% and lower. Geysirhead (talk) 16:45, 18 December 2022 (UTC)

Inconsistent graph colors - hard to compare
I’m referring to the 4 country maps illustrating each country’s sex ratio. Three of the graphs use blue = males and red = females. But one map uses red = males, blue = females. This makes it really hard to understand that map in context with the other three. These four maps should have consistent color assignments so that the series can be understood as a whole. 73.63.137.35 (talk) 23:26, 7 October 2023 (UTC)
