The vaginas sound wonderfully personalized, as the BBC reports. Doctors took scans of each girl's pelvis, then built biodegradable scaffolds to fit each girl. They took biopsies from each girl, then grew those cells in lab, coaxing muscle cells to grow on the outside of their scaffolds and epithelial cells to grow on the inside of their scaffolds. Annual biopsies since the implants show that the women have normal vaginal walls. The women also report they have normal levels of "desire, arousal, lubrication, orgasm, satisfaction, and painless intercourse," researchers reported in their paper.
