“…However, the few previous workers who have investigated these ligaments in the adult [ West man, 1926[ West man, , 1929[ West man, , 1937Decker, 1951;Mahran and Glialeb, 1964;Hendricks and Moawad, 1965;Gonzales de Vargas el at., 1976] have obtained results which indicate that they may directly contribute to the normal activity of the female reproductive tract. In view of these findings, knowledge of the detailed morphology of the ligaments would be of value in helping to establish their physiological role.…”

Histological and histochemical light-microscopy techniques, supplemented by electron microscopy have been used to study the structure and autonomic innervation of the uterine and ovarian ligaments in the adult rat and guinea pig. In both species, the smooth muscle of the uterine ligament was continuous with that of the myometrium at the tubouterine junction and with the smooth muscle of the ovarian ligament. The musculature of the latter also extended into the mesosalpinx and the ovarian bursa, capsule and hilus. Using electron microscopy, smooth muscle cells of both ligaments were usually separated from their neighbours by small amounts of connective tissue, although regions of close approach between adjacent cells were frequently observed. In these areas, the plasma membranes of apposing smooth muscle cells were separated by 10–15 nm and were devoid of an intervening basal lamina. Concerning the arrangement of autonomic nerves, the smooth muscle of the uterine and ovarian ligaments in both species was not supplied by acetylcholinesterase-containing nerves. In the guinea pig, however, numerous noradrenergic nerves were observed amongst the smooth muscle cells of the uterine and ovarian ligaments, the mesosalpinx and the ovarian capsule and bursa. These findings were confirmed using the electron microscope, in which nerve terminal regions*containing characteristic small, dense-cord vesicles were encountered lying 50–100 nm from adjacent muscle cells. In contrast, the smooth muscle cells of the rat uterine and ovarian ligaments were devoid of a noradrenergic nerve supply. These results have been correlated with the observations of previous workers, and the significance of the present findings, particularly in relation to the functional activity of the adult uterine and ovarian ligaments, has been discussed.

“…The frequency of contractions of the ovarian ligament varies during the menstrual cycle [Decker, 1951;Mohsin and Pennefother, 1979]. Because the greatest contractile activity of the ligament occurs at the time of ovulation in the human [Decker, 1951], it was postulated that the ligament might facilitate approximation of the ovary and oviduct [Blandau and Verdugo, 1976].…”

The structure of the human ovarian ligament was studied with light and electron microscopy, with emphasis on neural components. The ligament is primarily composed of smooth muscle arranged in an outer oblique and an inner longitudinal layer. The smooth muscle cells are connected by two types of intercellular junctional complexes, close contacts and intermediate junctions. The intercellular junctions may serve to coordinate smooth muscle activity and synchronize contractions of the ligament. Nerves are abundant and accompany the vascular supply. Specialized encapsulated neural structures previously reported were not observed. Acetylcholinesterase-positive nerves are more numerous than adrenergic nerves. Both types of nerves are associated with vascular smooth muscle. We conclude that these nerves either traverse the ligament or terminate in the ligament and are vasomotor.

“…Observations made in vivo by other investigators suggest that in the rabbit, monkey and man the oviduct, ovary and mesovarian ligaments contract in concert at the time of ovulation, thus drawing the ovary and fimbria into proximity, and aiding ovum collection (Westman, 1937(Westman, ,1950Elert, 1947;Decker, 1951;Blandau, 1971;Pauerstein, 1974). The increased motility in vitro of the uterovarian ligament of the rabbit at ovulation is consistent with these observations and may reflect increased activity in vivo at the time of ovulation.…”
