Perinatal outcomes of infants born to mothers with hyperemesis gravidarum: A systematic review and meta-analysis
2023, European Journal of Obstetrics and Gynecology and Reproductive BiologyEmbryo quality: the missing link between pregnancy sickness and pregnancy outcome
2017, Evolution and Human BehaviorCitation Excerpt :The birth sex ratio was extraordinarily female-biased. There is almost certainly an hCG link here, as female embryos produce more, and mothers of female embryos are more likely to experience hyperemesis gravidarum (Askling et al., 1999; Basso & Olsen, 2001; del Mar Melero-Montes & Jick, 2001; Peled et al., 2013). This would suggest that an elite stratum of offspring quality is being sampled in these drug trials.
An adaptive significance of morning sickness? Trivers-Willard and Hyperemesis Gravidarum
2016, Economics and Human BiologyCitation Excerpt :Another possibility is that NVP serves no particular purpose (Vikanes et al., 2008). Curiously, HG has been associated with girl births (Askling et al., 1999; Melero-Montes and Jick, 2001). Trivers and Willard (1973) (T-W) proposed that natural selection would favor mothers’ ability to adjust the sex ratio at birth according to condition: mothers in poor condition would produce more daughters, and mothers in good condition more sons.
Disgust in pregnancy and fetus sex-Longitudinal study
2015, Physiology and BehaviorCitation Excerpt :However, it would not explain the fetal sex impact on maternal disgust sensitivity during pregnancy. The DS-R [29] has been criticized in previous research, mainly due to the overlap between core disgust and contamination disgust, and also due to exclusion of sexual and moral disgust [32,44]. Sexual disgust evolved to avoid sexual partners and behaviors that would reduce one's long-term reproductive success [2], and moral disgust serve to avoid individuals who inflict social costs on oneself or members of one's social network [32].
