On intermammary distances and non-ptotic breasts

Realizing a dearth of scientific content, we felt obliged. The excellent Rolf Degen presents a female-centered paper on women’s intrasexual competition spiced with a couple of terms that could spruce up male conversation.

Women’s perceptions of breast size, ptosis, and intermammary distance: Does breast morphology play a role in women’s intrasexual competition?

Women’s breasts are considered attractive and sexually appealing, perhaps due to their residual reproductive value. However, most research has focused on their intersexual selective display. The current studies (N = 467) investigated the role of breast morphology on intrasexual competitive displays in women. Women with large breasts were rated [by other women] as more attractive, fertile, reproductively successful, likely to befriend, threatening, and they were rated as less likely to be introduced to a current partner. Considering that men are attracted to women’s breasts that convey information on residual reproductive value (ptosis. i.e., sagginess), it is likely that women did not want to present their partners with other women that may be viewed as want to present their partners with other women that may be viewed as possible competitors. Intermediate intermammary distances and non-ptotic breasts were perceived as being the most attractive by other women. Similar to previous studies on men’s perceptions of women’s breasts, large breast sizes (D-Cup) and high ptotic breasts were perceived to be higher in reproductive success. This suggests that women also interpret women’s breasts in a similar manner to men, and it would be advantageous from an intrasexual competitive perspective to be attentive to these features.
