[Effect of high altitude hypoxia on fetal development during pregnancy and the reason analysis].

ABSTRACT

High altitude hypoxia is an important factor to affect fetal development during pregnancy. In the special environment, maternal physiological functions are regulated to maintain the maternal and fetal homeostasis, so that limited oxygen is to meet the needs of fetal growth and development. In this review, the literatures about the effects of hypoxic environment on fetal development during pregnancy in recent years were summarized, in which the fetal growth characteristics, maternal physiological regulation, genetic and placental influencing factors in high altitude areas were involved. This may be helpful for the reproductive healthcare of women in high altitude region, and also for the treatment and prevention of fetal growth retardation in the hypoxic environment.
