“The Effects of Hormones in Milk on Infertility in Women”
We’ve known dairy food intake is sometimes been associated with infertility, however little is known with regard to associations with reproductive hormones or anovulation, meaning you know how might dairy do it by affecting how the uterus prepares or affecting the ovary itself. The researchers found that women who ate yogurt or cream had about twice the risk of sporadic anovulation, meaning failure of ovulation. So in some months there was just no egg to fertilize at all.
In light of women delaying pregnancy until an older age, the identification of reversible factors that may affect the individual decline might be of significant clinical value. So they did ultrasounds on all the women and studied their diets and concluded that higher dairy protein intake was associated with lower antral follicle count, in other words, accelerated ovarian aging.
a. It could be the steroid hormones in growth factor.
b. The contamination of milk products with pesticides and endocrine disrupting chemicals that may negatively affect the development of these varying follicles and egg competence.
Regarding the hormones, a study suggests that commercial milk derived from both pregnant and non-pregnant animals contains large amounts of estrogens, progesterone and other placental hormones that are eventually released into the human food chain with dairy intake accounting for sixty to eighty percent of the estrogens consumed as I mentioned before.
It’s not just cows that have been, you know, injected with growth hormones. These hormones are just in their bodies naturally. And once inside the human body, these bovine hormones get converted to oestrone and oestradiol, the main active human estrogens, and following absorption bovine steroids may then affect reproductive outcomes. It’s imperative that further studies are designed to clarify the biology underlying the observed associations.
This might be crucial, given that consumption of another species’ milk by humans is an evolutionarily novel dietary behavior that is the potential to alter reproductive parameters and may have long-term adverse health effects.
“牛奶中的激素对女性不孕所造成的影响”
我们已经知道乳制品的摄入有时会和女性不孕有关。然而，我们对于乳制品的摄入和生殖激素，以及女性停止排卵之间的关联知道得太少了。也就是说，我们其实知道，食用乳制品会影响到子宫的备孕或者卵巢自身，从而影响到女性的生殖激素或者排卵。研究人员发现，吃酸奶或者奶油的女性会出现不定期的停止排卵，也就是说她们的排卵失败风险增加了两倍。所以她们有些月份根本就没有卵子排出也就无法受孕。
虽然，卵巢库存量的减少是女性不孕的重要原因之一，但我们对生育能力随着年龄增长逐渐退化的了解依然太少，鉴于许多女性选择推迟她们的生育年龄，找到改善卵子减少的逆转因素，可能有重要的临床价值。所以研究人员对这些女性进行了超声波检查，并研究了她们的饮食。最后得出的结论是：高的乳制品蛋白质摄入量和低的窦卵泡数息息相关。换句话说，也就是乳制品蛋白质的大量摄入加速了卵巢老化。
其一：可能是生长因素中的类固醇激素。其二：奶制品被农药以及其他破坏内分泌的化学制剂所污染，这些污染对卵巢内窦卵泡的成长以及卵子的质量产生了负面影响。卵子的质量和激素有关，研究认为商店里卖的牛奶，无论是来自未孕还是怀孕的奶牛，都含有大量的雌性激素、黄体酮以及其他胎盘激素。
不光是那些被注入生长激素的奶牛，我们也该意识到这些激素是自然存在于动物体内的。这些激素一旦进入人体，会被转变为雌激素酮和雌二醇，这些是人类主要的雌激素。人体吸收这些激素之后，牛类固醇可能会影响人类的生育能力。我们必须开展进一步的研究，来搞清楚我们所观察到的这个关联背后的生物学原理。
这项研究可能很重要，因为人类在喝着另一种物种的奶，这在进化史上是一种异常的饮食行为，这种行为有可能改变人类的生育参数，同时对健康可能也有着长期的负面影响。
