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调节第一性征，如每月卵巢基质的变化促进了卵子成熟和排卵，以及作为月经周期一部分的子宫的变化。

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，因为禁药物在用治疗未成年人的其他疾病时是完全合法的，这些疾病包括子宫异位症等慢性疾病以及性早熟或青春期发育迟缓。

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，那么新胚胎依偎在子宫中怀孕——但是子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.

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， 称为巨噬细胞的免疫细胞可能与子宫异位症有关， 痛觉神经也参与其中。

The endometrium evolved to make implantation difficult

子宫断演化 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.

如果卵子没有受精，螺旋动脉将收缩，子宫的表层也因此凋亡。

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，子宫变厚，有助受精；黄体期，螺旋动脉产生可以为增厚的子宫提供更多养分。

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

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.

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，此时子宫（或子宫衬）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子宫的再生，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子宫异位症的检测方法。

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

子宫经过演化， 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，以促进卵细胞成熟和排卵，同时它还影响子宫在月经周期的改变。
