助孕小知识:怀孕“神助攻”-维生素D Vitamin D and Fertility

日期 2018-09-26
总所周知,维生素D 是一种脂溶性维生素,在人体健康中扮演了很多重要的角色。其中最重要的是维持骨骼的健康,而且还在免疫和基因表达上发挥了重要作用。
 
近年的多项研究发现,维生素D对于生育也非常重要。身体中正常的维生素D水平有助于增加受孕率,也有助于宝妈们有一个健康的宝宝。你可能不知道,维生素D受体分布在很多女性器官中,比如卵巢,子宫和胎盘。有的研究发现,在接受试管婴儿治疗的病人中,维生素D水平正常的人的怀孕率>低的人。有的研究发现,女性自然流产发生率维生素D低的人>正常水平者。 还有的研究认为,维生素D在孕期中关键作用只是在子宫里的。
 
看起来似乎维生素D和试管成功率关联,它在生殖领域的重要作用可能表现在对内膜的作用上。它不仅影响生育力,而且影响整体健康状况。因此,为了提高受孕的效果和宝宝的健康,建议备孕的妈妈们检查一下自己的维生素D血值。结果显示维生素D缺乏的话需要遵医嘱补充维生素D以达到一个正常的水平(血指标达到或高于25ng/ml)哦。

Vitamin D is a fat-soluble vitamin with multiple important roles in the human body. The most important role of Vitamin D in the body is maintaining bone health. Vitamin D has also important roles for immunity and gene expression.

Recent studies revealed that vitamin D has an important role for fertility. It appears that maintaining a normal vitamin D level may improve your chance of conceiving and having a healthy pregnancy. In fact, the vitamin D receptor is present in many female organs including the ovary, uterus and placenta. Recent study showed that women with normal vitamin D levels had a significantly higher chance of pregnancy from IVF compared to those with lower levels of vitamin D. Another study suggested the critical role of vitamin D in pregnancy may be within the uterus. Recently, the study showed the increased spontaneous miscarriage rate in women with low Vitamin D levels compared with those with normal levels.

It appears that vitamin D levels are associated with IVF success and that its important role in reproduction may be at the endometrium. Vitamin D deficiency can not only affect fertility but also overall health. Thus, all fertility patients should be counseled about Vitamin D supplementation (if the level is low) to achieve the normal vitamin D level (30ng/ml or higher) to improve pregnancy outcomes and for general health benefits.
