Retroversions refer to the position of an organ or a body part that is tilted or facing backward. The antonyms for retroversions are anteflexion or anteflex, which refer to the forward bending of an organ or a body part. Anteflexion can occur in different parts of the body, such as the uterus, urinary bladder, or the vertebral column. In contrast, retroversion is often associated with the uterus or the pelvis, where it can lead to complications like infertility, pain, or discomfort. Anteflexion, on the other hand, is considered a normal and healthy position for many organs and structures in the body, allowing them to function properly without causing any problems.
