Spontaneous Abortion -

Résumé :
This series of volumes dealing with reproductive health care has as its primary objective the improvement of the quality of human reproduction. The of knowledge and new technology give us opportunities as never explosion before to accomplish this end. The Editor has brought together contributors who are outstanding scientists from around the world. A number of the authors have personally made significant contributions to our body of knowledge in reproductive medicine. Bringing all this information together in an easily readable format is a great service. This is essential reading for all concerned with the control and improvement of human reproduction and the correction of its many deficits. xv P'art I Physio-anatom-ical Parameters 1 Uterine microvasculature and spontaneous abortion M. TAKADA In the implantation and subsequent development of a fertilized ovum, its integrity is most significant. However, with maternal local factors, i.e., unsatisfactory uterine conditions, implantation may not succeed even if the integrity of the fertilized ovum is excellent; if implantation is made, the maturation of the fetoplacental unit following implantation is disturbed, which leads to abnormalities in fetal development or to miscarriage. Thus, the uteroplacental unit, as well as the fetoplacental unit, plays an important role in the establishment and maintenance of pregnancy. Among the mechanisms of the utero placental unit, most significant is the physiological mechanism of the uterine microvasculature and its correspon? dence to gestation. In particular, homeostasis of simultaneous cooperative development of the uterine wall and the placenta is most important.
