Abstract: Intravaginal devices for presenting ejaculate produced during sexual intercourse to the cervix while inhibiting exposure to the intravaginal environment and associated methods are disclosed herein. An intravaginal device configured in accordance with embodiments of the present technology can include, for example, a tubular body having a first concave surface that defines a first depression at which to collect ejaculate produced during sexual intercourse, a second concave surface that defines a second depression at which to present the ejaculate to the external os, and a flow channel defined by an inner surface of the tubular body extending between the first and second depressions. Because ejaculate deposited into the first depression travels to the second depression through the flow channel, exposure to the inhospitable conditions of the intravaginal environment is limited. Moreover, by guiding the ejaculate through the external os, the intravaginal device may serve to increase intrauterine sperm count.
