Abstract
Abstract A study of vascular patterns in the human ovary has been presented. The vascular system in the human ovary is more complex than that of the rabbit. However, it shows helical spiralling with gradual diminishing diameters in the branches of the main ovarian artery. The function of spiralling in the ovarian branches of the arterial system are (1) adaptation of the vasculature to ovarian growth, and (2) to provide a mechanism for the reduction and regulation within the ovary of blood pressure. A relationship exists between arterial spiral distortion resulting from ovarian cysts, corpora lutea, and the arrangement of the ovarian veins. Characteristics of the ovarian artery and its branches have been described. The relation of the condition of the vessels to ovarian activity and inactivity have been discussed. It is suggested that there is a relation between growth and development of ovarian arterial branches and estrogenic activity in the adult. Evidence is presented to show that branching of the arteries in the ovary from late fetal life to shortly after birth is under the influence of maternal hormones. Observation of the venous vascular tree shows completely different characteristics when compared to the arteries.
