Lower levels of estrogen would lower the risk of breast and endometrial cancers.

During puberty, waves of estrogen and progesterone regulate primary sex characteristics, like monthly changes to the ovary stroma to promote egg maturation and ovulation, and changes to the uterine wall lining as part of the menstrual cycle.

在青春期，雌激素和孕酮水平的波动会调节第一性征，如每月卵巢基质的变化促进了卵和排卵，以及作为月经周期一部分的宫内膜的变化。

The challengers contend the law unconstitutionally discriminates based on sex because the banned medications are perfectly legal when used to treat other conditions in minors, conditions that range from chronic diseases like endometriosis to early or late onset puberty.

质疑的人认为该法律基性别歧视，违反宪法，因为被禁药物在用治疗未年人的其他疾时是完全合法的，这些疾宫内膜异位症等慢性疾以及性早或青春期发育迟缓。

If fertilization does happen, then the new embryo snuggles into the endometrium for gestation — but the uterus is only receptive to implantation for a short time, about a week after ovulation.

如果受精确实发生了，那么新胚胎会依偎在宫内膜中怀孕——但是宫只接受着床很短的时间，大约在排卵后一周。

If the egg is fertilized and embeds itself in the thick uterine lining, the lining is not shared, and thus menstruation does not occur and the woman becomes pregnant.

如果卵受精并嵌入到厚的宫内膜中，内膜就不会被共享，因此月经就不会发生，女性就会怀孕。

Regular coffee consumption is associated with a decreased risk of several cancers (including breast, prostate, colorectal and endometrial), cardiovascular disease, type 2 diabetes, Parkinson's disease, dementia and possibly depression and suicide.

By then, researchers had already discovered that immune cells called macrophages probably contribute to endometriosis and that pain-sensing nerves are also involved.

那时，研究人员已经发现， 被称为巨噬细胞的免疫细胞可能与宫内膜异位症有关， 痛觉神经也参与其中。

The endometrium evolved to make implantation difficult

宫内膜不断演化 使得着床变得困难。

If fertilization doesn't occur, the spiral arteries collapse, and the superficial layers of the endometrium die.

如果卵没有受精，螺旋动脉将会收缩，宫内膜的表层也会因此凋亡。

During the follicular phase of the menstrual cycle, the endometrium thickens in case fertilization occurs, during the luteal phase, spiral arteries emerge to bring more nutrients to support the thick endometrium.

在月经周期中的卵泡期，宫内膜会变厚，有助受精；黄体期，螺旋动脉产生可以为增厚的宫内膜提供更多养分。

Just days after fertilization, the embryo implants in the lining of the uterus.

在受精后的几天内，胚胎就会被植入宫内膜。

Because the egg has not been fertilized, the uterus lining called the endometrium is not needed, and hence it breaks down and is lost through the vaginal canal with some blood.

因为卵没有受精，宫内膜就不被需要了，因此它会分解，随着一些血液通过阴道管道流失。

During puberty, the monthly menstrual and ovarian cycles begin, which is when the endometrium, or inner lining of the uterus, goes through cyclic changes in response to the ovarian hormones.

在青春期，月经和卵巢周期开始出现，此时宫内膜（或宫内衬）对卵巢激素作出反应，发生周期性变化。

The rising estrogen levels in the follicles stimulate the regeneration of the endometrium, building a cushy, well-vascularized habitat for another potential fertilized egg to call home.

卵泡中雌激素水平的上升刺激宫内膜的再生，为另一个潜在的受精卵建立一个舒适、血管发达的栖息地。

We are very keen to develop a test for endometriosis using menstrual blood.

我们非常热衷利用月经血开发一种宫内膜异位症的检测方法。

The endometrium evolved to make implantation difficult so that only the healthy embryos could survive.

宫内膜经过演化， 使得着床难以进行因此，只有健康的胚胎能够生存。

Waves of estrogen and progesterone regulate monthly changes to the ovary stroma to promote egg maturation and ovulation, and as well, it changes to the uterine wall lining as part of the menstrual cycle.

雌激素和孕酮的周期性改变可调节卵巢基质每月的变化，以促进卵细胞和排卵，同时它还影响宫内膜在月经周期内的改变。
