Forensic facial reconstruction accurate reconstruction possible is largely limited. A second problem is the lack of a methodological standardization in approximating facial features. A single, official method for reconstructing the face has yet to be recognized. This also presents major setback in facial approximation because facial features like the eyes and nose and individuating characteristics like hairstyle - the features most likely to be recalled by witnesses - lack a standard way of being reconstructed. Recent research on computer-assisted methods, which take advantage of digital image processing, pattern recognition, promises to overcome current limitations in facial reconstruction and linkage. Reconstructions only reveal the
Birth defects of diethylstilbestrol also have an increased risk of uterine fibroids, and incompetent cervix in adulthood. Studies of DES daughters have not found a link between "in utero" exposure to DES and autoimmune diseases. In an animal model designed to study environmental estrogens, DES turned out to be an obesogen capable of causing adult weight gain in female mice which had been exposed to DES during neonatal development. The excess weight gain was not apparent at birth or in infancy, but occurred in adulthood. Initially, fewer studies documented risks of prenatal exposure to DES on males (referred to as "DES sons"). In the
