目的研究哺乳期妇女不同喂养方式的生育力恢复。方法 １０４ 例对象分为母乳、混合、人工喂养三组，观察和记录宫颈粘液，其中３３例连续测定了血生乳素和雌二醇。３２例测定了尿雌激素和（或）孕二醇。结果 产后第１次来经的平均日三组分别为１９８．１６、 １７５．３５和９１．４４ｄ，第２次与第１次月经间隔的平均日三组分别为６７．５０、２８．５７和２３．２８ｄ，经统计分析，母乳、混合与人工喂养组之间都有显著差异（Ｐ＜０．０５）。宫颈粘液法估计月经恢复的正确性为８６．５３％，血生乳素和雌二醇的比例预测月经恢复的灵敏度达９３．２４％、特异性为８９．２８％，１２例混合喂养者尿孕二醇水平均＜７．１０μｍｏｌ／２４ｈ，表明无排卵发生。结论 应用宫颈粘液观察法了解生育力简单、正确，妇女自己能掌握，可推广。遇到识别粘液有困难时，作内分泌测定，可了解生育力的恢复。
Objective To study the fertility restoration of different breastfeeding women during feeding. Methods One hundred and four subjects were divided into three groups: breast milk, mixed group and artificial feeding group. Cervical mucus was observed and recorded. Of the 33 cases, blood lactogen and estradiol were continuously measured in 33 cases. Thirty-two patients tested urinary estrogen and / or pregnanediol. Results The first three days after delivery were 198.16, 175.35 and 91.44 days, respectively, and the average daily doses of the second and the first menstrual interval were 67.50, 28.57 and 23.28d, by statistical analysis, breast milk, mixed and fed groups were significantly different (P <0.05). Cervical mucus method estimated that the correctness of menstrual recovery was 86.53%, the ratio of lactogen and estradiol predicted menstrual recovery sensitivity of 93.24% and specificity of 89.28%, 12 cases of mixed feeding urine pregnancy Diol levels were <7.10μmol / 24h, indicating anovulation occurred. Conclusions Cervical mucus observation method to understand fertility is simple, correct, women themselves can grasp, can be promoted. Encountered when there are difficulties identifying mucus, for endocrine testing, to understand the restoration of fertility.
