According to science author Mark Thompson, the 2suit was cumbersome but moderately successful, and it is not clear that the 2suit will have practical value for future space travelers. It took eight attempts for two test participants to successfully embrace one another. Functionality testing was conducted in 2008 by Bonta aboard G-Force One, a low-gravity simulator. However, Bonta stressed that the 2suit was versatile, and wasn't intended for the sole purpose of sex. The 2suit was made of a lightweight fabric, with a Velcro-lined exterior, which would enable two people to securely embrace. In 2006, American novelist Vanna Bonta invented the 2suit, a garment designed to facilitate sex in weightless environments such as outer space, or on planets with low gravity. Currently no mice or rats have developed while in microgravity throughout the entire life cycle. Although this resulted in healthy mice once implanted at normal gravity, the fertilization rate was lower for the embryos fertilized in microgravity. Another study examined mouse embryo fertilization in microgravity. Studies conducted on rats revealed that, although the fetus developed properly once exposed to normal gravity, rats raised in microgravity lacked the ability to right themselves. It is important to study how space environment affects critical phases of mammalian reproduction and development as well as events surrounding fertilization, embryogenesis, pregnancy, birth, postnatal maturation, and parental care. Life on Earth, and thus the reproductive and ontogenetic processes of all life, evolved under the constant influence of the Earth's 1 g gravitational field. The primary issue to be considered in off-Earth reproduction is the lack of gravitational acceleration. Such effects would be a result of factors including gravity changes, radiation, noise, vibration, isolation, disrupted circadian rhythms, stress, or a combination of these factors. ![]() Numerous physiological changes have been noted during spaceflight, many of which may affect sex and procreation. Santaguida and colleagues (2022) have further argued that space agencies and private companies should invest in this discipline to address the potential for sexual harassment and assault in space contexts. ![]() Dubé and colleagues (2021) proposed that NASA should embrace the discipline of space sexology by integrating sex research into their Human Research Program. Despite this, some researchers have argued that national and private space agencies have yet to develop any concrete research and plans to address human sexuality in space. Īs of 2009, with NASA planning lunar outposts and possibly long-duration missions, the topic has taken a respectable place in life sciences. The discussion of sex in space has also raised the issue of conception and pregnancy in space. If the couple have a combined velocity relative to other objects, collisions could occur. Some difficulty could occur due to drifting into other objects. Consequently, their actions will not change their velocity unless they are affected by another, unattached, object. According to the law, if the couple remain attached, their movements will counter each other. Human sexual activity in the weightlessness of outer space presents difficulties due to Newton's third law. Sex in space is a part of space sexology. Issues include disrupted circadian rhythms, radiation, isolation, stress, and the physical act of intercourse in zero or minimal gravity. ![]() The conditions governing sex in space (intercourse, conception and procreation while weightless) have become a necessary study due to plans for long-duration space missions.
