The integration of reproductive medicine and torso sex doll technology is opening Pandora's box. The artificial uterus simulation system developed by a laboratory enables surrogate mothers to sense the development status of the fetus in real time through multi-level pressure feedback on the abdomen of the new sex doll. Although this technology improves the success rate of pregnancy, ethicists warn that it may exacerbate the commodification of the body. A more radical application is "virtual gene recombination" - partners test the visual effects of different combinations of genetic characteristics on torso sex dolls. This pre-birth aesthetic rehearsal is blurring the boundaries between natural reproduction and technological design.
