近日，发表在美国医学杂志《生殖与不育》的哈佛大学所做的最新研究显示，在接受IVF 试管婴儿治疗过程中，每天多摄入一种含糖饮料的妇女，将会减少其怀孕机会：
每天喝多于一种含糖饮料（比如可乐）可将活产率减少16％。
每天喝一份含糖饮料，会降低IVF成功率12％。
主要原因可能是：
*饮料减少卵巢卵子的数量和成熟度，以及降低高质量胚胎数目；
*过去的研究表明，饮料中的糖会刺激应激激素， 阻碍生殖能力。
*卵子和胚胎在高血糖环境中也可能无法正常发育成长。
这项研究是通过分析了2014 到2016 年，340名接受试管婴儿治疗的妇女得到的。

Women who consume more than one sugary drink a day while undergoing IVF cut their chances of conceiving, Harvard study reveals
Drinking more than one sugary drink a day reduces live births by 16%
Having just one sugary drink a day prevents chance of successful IVF by 12%
Drinks reduce the number and maturity of ovarian cells, and embryo quality

Women who consume sugary drinks while having IVF cut their chances of conceiving, new research reveals.
Drinking more than one sugary beverage a day reduces a woman's chance of having a live birth after IVF by 16 percent, a Harvard University study found.
Having just one sugary drink a day lowers the chance of successful IVF by 12 percent, the research adds.
Sugary drinks also reduce the number and maturity of a woman's ovarian cells, as well as lowering the amount of high-quality embryos, the study found.
Previous research suggests sugar stimulates the release of stress hormones that affect the health of the reproductive system. Eggs and embryos may also fail to thrive in high blood glucose environments.

How the research was carried out
Researchers from Harvard University analyzed 340 women undergoing IVF between 2014 and 2016.
The study's participants were investigated during the second stage of IVF treatment, known as ovarian stimulation, when the goal is to harvest as many mature eggs as possible from the ovaries.
They completed a questionnaire to assess their drink consumption.
The participant's IVF outcomes were determined through their medical records.
More than one sugary drink a day cuts IVF success by 16%
Results reveal drinking more than one sugary drink a day reduces women's chances of having a live birth following IVF by 16 percent.
Having one such beverage a day lowers the chances by 12 percent.
Sugary drinks reduce the number, maturity and fertilization prospects of ovarian cells, as well as minimizing the amount of high-quality embryos, during IVF.
No link was found between coffee, caffeinated drinks or diet sodas and a woman's IVF prospects.
Previous research suggests sugar stimulates the release of stress hormones that affect the health of the reproductive system. Eggs and embryos may also fail to thrive in high blood glucose environments.
The findings were published in the journal Fertility and Sterility.
