It has been suggested that facial shape can serve as a signal for underlining biological condition, and that it is correlated with, among others, health, fertility, and attractiveness. In this study, 14 women were photographed during three consecutive trimesters of pregnancy, and the levels of their facial sexual dimorphism, asymmetry, and averageness were computed. Facial sexual dimorphism in first trimester was higher than in the second trimester (F(2, 22) = 5.77; p = 0.01; \u03b7p2 = 0.34, post-hoc Tukey HSD test p = 0.007). Similar pattern was visible for asymmetry (F(2, 22) = 3.67; p = 0.04; \u03b7p2 = 0.25, post-hoc Tukey HSD test p = 0.05). No statistically significant changes in measurement of averageness were observed. Results from Bayesian complementary analyses confirmed the observed effects for sexual dimorphism. The evidence for trimester differences in asymmetry and averageness was inconsequential. Based on the preliminary results of this exploratory study, we suggest that previously found decrease in observed facial attractiveness during pregnancy can be related to the decrease in computed facial femininity (possibly mediated by the changes in facial adiposity).<\/jats:p>","DOI":"10.3390\/sym13101944","type":"journal-article","created":{"date-parts":[[2021,10,17]],"date-time":"2021-10-17T23:25:15Z","timestamp":1634513115000},"page":"1944","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Changes in Facial Shape throughout Pregnancy\u2014A Computational Exploratory Approach"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6851-4513","authenticated-orcid":false,"given":"Urszula Maria","family":"Marcinkowska","sequence":"first","affiliation":[{"name":"Department of Environmental Health, Faculty of Health Sciences, Jagiellonian University Collegium Medicum, 31-066 Cracow, Poland"}]},{"given":"Anna","family":"Ziomkiewicz-Wichary","sequence":"additional","affiliation":[{"name":"Department of Anthropology, Institute of Zoology and Biomedical Research, Jagiellonian University, 30-387 Cracow, Poland"}]},{"given":"Natalia","family":"Nowak-Szczepanska","sequence":"additional","affiliation":[{"name":"Department of Anthropology, Ludwik Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, 50-137 Wroc\u0142aw, Poland"}]},{"given":"Danuta","family":"Kornafel","sequence":"additional","affiliation":[{"name":"Department of Human Biology, University of Wroclaw, 50-137 Wroc\u0142aw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0584-4427","authenticated-orcid":false,"given":"S\u0142awomir","family":"Kozie\u0142","sequence":"additional","affiliation":[{"name":"Department of Anthropology, Ludwik Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, 50-137 Wroc\u0142aw, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6175-3928","authenticated-orcid":false,"given":"Dariusz P.","family":"Danel","sequence":"additional","affiliation":[{"name":"Department of Anthropology, Ludwik Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, 50-137 Wroc\u0142aw, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"519","DOI":"10.1146\/annurev-psych-113011-143831","article-title":"Social Attributions from Faces: Determinants, Consequences, Accuracy, and Functional Significance","volume":"66","author":"Todorov","year":"2015","journal-title":"Annu.
