%0 Journal Article %T THE EFFECT OF THICKNESS AND PATTERN OF ENDOMETRIUM ON SUCCESS RATE ON HCG DAY IN INFERTILE COUPLES TREATED WITH OVULATION INDUCTION VIA GONADOTROPINS AND INTRAUTERINE INSEMINATION %J - %D 2018 %X Aim: Ovulation induction and intrauterine insemination is the first line therapy chosen for infertile couples. In this study, we investigated the effect of endometrial thickness and endometrial pattern; examined on HCG day, on the success rate of OI-IUI performed in unexplained infertility cases on the day of HCG. Material and Method: In this study 101 couples and 132 IUI cycle who were diagnoses unexplained infertility were examined prospectively. Results: 22 successful pregnancy was achieved in 132 cycles, the rate of pregnancy was calculated as %16.6 per cycle and %21.7 per patient. There was no significant difference between clinically proved pregnancy-positive and negative outcome groups regarding FSH dosage, duration of stimulation, basal FSH level, basal E2, TPMSS, number of IUI cycle, follicle diameter. Infertility period was calculated as 2.1 ¡À 1.4 years, and 4.1 ¡À 2.3 years positive and negative outcome groups respectively. The difference was statistically significant (p < 0.05). The number of an antral follicle and follicle count on HCG day was significantly different on pregnancy positive group compared to pregnancy negative group (p< 0.05). Endometrial thickness was measured as 9.8¡À1.1 mm and 9.6¡À3.5 mm in groups with positive and negative outcomes respectively. There was no significant difference regarding endometrial thickness and endometrial pattern. Result: There was no significant difference between pregnancy clinically proven and unproven groups in terms of endometrial thickness and endometrial pattern on the day HCG performed %K infertilite %K ovulasyon ind¨¹ksiyonu %K endometriyum %U http://dergipark.org.tr/zktipb/issue/40283/460247
