有些研究表明扎管后妇女黄体中期血清孕酮水平明显下降,而雌二醇水平似属正常范围。也有研究说明扎管后总的雌激素生成减少,雌/孕激素比率失衡,一般认为卵巢局部高压是扎管后宫血异常和月经过多的原因。为了进一步证实以上论点,作者对扎管后妇女卵巢内甾体生成及对脂质代谢影响进行了研究。研究包括112例扎管2年以上经产妇,年龄<46岁,月经规则,未行过其他重大妇科手术,于月经来潮前收集24小时尿液共7天,记录月经卡。根据妇女扎管后出现的问题分成3类:Ⅰ宫血异常和/或月经过多(经期延长超过2天和总行经天数超过7天);Ⅱ伴有雌激素不足症状和主诉的体力问题(肌肉、骨骼,泌尿生殖、心血管系统症状);Ⅲ心理和/或精神问题。对照组55例,年龄20～43岁,均未用避孕方法,3个月内未用 OC,也未行过
Some studies have shown that women with midbrain ligation after progesterone serum progesterone levels decreased significantly, while estradiol levels seem to be within the normal range. There are also studies show that total estrogen production after cesarean reduction, estrogen / progesterone ratio imbalance is generally believed that local ovarian hypersensitivity is the cause of abnormal posterior uterine bleeding and menorrhagia. In order to further confirm the above argument, the authors study the effects of steroidogenesis and lipid metabolism in the ovaries of women after cerclage. The study included 112 patients with maternal age of 2 years or more who were <46 years old and had regular menstruation without major gynecological surgery. Urine was collected for 24 hours before menstruation for a total of 7 days and the menstrual card was recorded. According to women’s problems after cerclage is divided into three categories: Ⅰ abnormal menstruation and / or menorrhagia (menstrual prolongation of more than 2 days and the total number of days by more than 7 days); Ⅱ with estrogen deficiency symptoms and complaints of physical problems Muscle, bone, genitourinary, cardiovascular system symptoms); Ⅲ psychological and / or mental problems. Control group of 55 patients, aged 20 to 43 years, did not use contraception, did not use OC within 3 months, nor did
