Caution with Use Birth Control Pills If You Plan to Have Children in the Future！

Young women often choose birth control pills to address issues like dysmenorrhea (painful periods) or irregular menstruation after puberty, or to temporarily prevent pregnancy for several years.

Birth control pills primarily work through two mechanisms:

1. Disrupting the hypothalamic-pituitary-ovarian (HPO) axis, which affects the formation of dominant follicles and suppresses ovulation.

2. Altering endometrial development, reducing the endometrium’s responsiveness to estrogen and thinning the uterine lining.

After years or even a decade of use, when women discontinue the pills, a significant portion experience incomplete recovery of HPO axis function. The endometrium often remains thin, leading to difficulties in conception. Even if pregnancy occurs, the thin endometrium may fail to provide adequate blood supply and nourishment for the fetus, increasing risks of miscarriage, or fetal developmental issues. In cases of assisted reproductive technologies (e.g., IVF), the compromised HPO axis and endometrial conditions may still struggle to sustain a full-term pregnancy.

年轻女性，选择用避孕药，大多因为月经来潮后，有痛经或月经不调，有的暂时要避孕几年。

避孕药其中有2个作用：（1）干扰下丘脑-垂体-卵巢（HPO）轴，影响优势卵泡的形成，抑制排卵；（2）影响子宫内膜发育，降低内膜对雌激素的反应，使内膜变薄；

侍几年或十多年后，停用避孕药后，有相当一部分女性，干扰下丘脑-垂体-卵巢（HPO）轴功能没有完全恢复，子宫内膜仍然很薄，造成女性不易受孕，或怀孕后，由于子宫内膜薄，没有足够气血滋养胎儿，怀孕后容易胎死，流产。用人工受精后，HPO轴功能没有完全恢复和子宫内膜过薄，也难于支撑10月怀胎。
