Endometrial thickness measurement by TVS predicts pregnancy rates

Objective: to evaluate the influence of endometrial pattern and thickness on number of pregnant patients after intrauterine insemination. material and methods: all patients received sequential 150 mg clomiphene citrate from cycle day 2 to 6 and followed by follicle stimulating hormone from 7 day to day 10 of cycle. from day 10 serial transvaginal ultrasonography was performed to monitor follicular growth and endometrial pattern thickness by human chorionic gonadotrophin. when follicle size was more than 18 mm human chorionic gonadotrophin was given i/m. 36 hrs after the injection,intrauterine insemination was performed. endometrial thickness was also emphasized. main out come measured number of pregnancies achieved among treated patients. results: out of a total 500 patients,152(30%) patients conceived. 322 patients had endometrium >10 mm thick,out of which 110(34%) conceived,whereas 178 patients had <10mm endometrium out of which 41(23%) conceived pregnancy. conclusion: in infertile women,on the day of human chorionic gonadotrophin administration less than 10 mm endometrial thickness predicts significantly less chances of pregnancy as compared to thick endometrium.
