目的:探讨排卵期子宫内膜的厚度在不孕症临床治疗中与妊娠的关系,寻找排卵期子宫内膜厚度的最佳状态,提高不孕症的治愈率。方法:用阴道B超在子宫矢状面测得排卵期子宫内膜厚度的最大值。监测非夫精人工授精资料完整者共200例,433个周期,妊娠人数112人。结果:子宫内膜厚度≤7ram或>14mm,周期妊娠率为0,子宫内膜厚度在8mm～9mm时,周期妊娠率为14.81%,子宫内膜厚度在10mm～12mm时,周期妊娠率为30.77%,子宫内膜厚度在13～14mm,周期妊娠率为21.6%。提示:排卵期子宫内膜最佳厚度为10mm～12mm,经X~2检验,P<0.01,有极显著差异。结论:在胚胎植入过程中,子宫内膜发生蜕膜反应进入敏感期,才能容许胚胎着床。在不孕症临床治疗中,我们要力争卵泡与子宫内膜发育同步,创造条件,使排卵期子宫内膜的厚度达到10mm～12mm最佳状态,使子宫内膜发育适应于卵孕着床时的条件,以提高妊娠率。若排卵期子宫内膜厚度≤7mm或>14mm时,可考虑放弃该周期治疗。
Objective: To investigate the relationship between ovulation endometrial thickness and pregnancy in the clinical treatment of infertility, find out the best condition of ovulation endometrial thickness and improve the cure rate of infertility. Methods: Vaginal ultrasound in the uterus sagittal measured ovulation endometrial thickness maximum. A total of 200 cases of non-precision artificial insemination monitoring information, 433 cycles, the number of pregnant 112. Results: Endometrial thickness ≤7mm or> 14mm, cycle pregnancy rate was 0, the endometrial thickness of 8mm ~ 9mm, the cycle pregnancy rate was 14.81%, the endometrial thickness of 10mm ~ 12mm, the cycle pregnancy rate was 30.77 %, Endometrial thickness in 13 ~ 14mm, cycle pregnancy rate was 21.6%. Tip: ovulation endometrial thickness of the best 10mm ~ 12mm, by X ~ 2 test, P <0.01, a very significant difference. Conclusion: During the process of embryo implantation, the decidual reaction in the endometrium enters the sensitive period, which allows the embryo implantation. In clinical treatment of infertility, we should strive to follicles and endometrial development simultaneously, to create the conditions so that the ovulation endometrial thickness of 10mm ~ 12mm best state, so that endometrial development adapted to the pregnancy of the egg Conditions to improve pregnancy rates. If the ovulation endometrial thickness ≤ 7mm or> 14mm, consider giving up the cycle of treatment.
