Repeated abortions and chromosome analysison was an intrinsic abnormality in the fertilized ovum. There have been numerous reports of abnormalities which cause fetal wastage (Carr, 1970; Boué and Boué, 1973; Creasy .., 1976; Lauritsen, 1976). Sixty percent of detectable first trimester abortions are chromosomally abnormal (Boué and Boué, 1975; Lauritsen, 1976).大笑 发表于 2025-3-23 22:33:54

Control of uterine activity in pregnancyity. During the greater part of gestation, myometrial contractions are infrequent and of low intensity. Possibly, the slow and very gradual distension of the muscle wall by the growing conceptus prevents up to a point the appearance of trains of contractions leading to expulsion of the latter.
