- Abstract
This minireview reports current hypotheses concerning the remodeling of sympathetic innervation in rodent and human uterus during the estrous cycle and gestation. Neural modulation in this organ is related to sexual hormone concentrations, and a reduction in nerve density is observed when estrogen levels are high during the estrous cycle. Estrogen receptor alpha is considered to be the major receptor mediating the action of estrogen. In the uterus, the expression of neurotrophins, such as nerve growth factor, which are involved in the survival and growth of nerve fibers, changes in response to steroid levels. Despite much research, further studies are necessary to clarify various aspects of nerve growth control under diverse physiological conditions. These studies could be of importance, since alterations of the biological mechanisms of uterus innervation may play significant roles in various pathologies, such as infertility and spontaneous abortion.
