In order to explore the impact of endometrial thickness on hCG administration day on ongoing pregnancy rate (OPR) in IVF-ET cycles, we retrospectively analyzed data from 10,406 patients undergoing their first IVF cycles with standard gonadotropin releasing hormone analogue (GnRH-a) long protocol. Firstly, patients were divided into poor (≤ 5 oocytes), medium (6-14 oocytes), and high (≥ 15 oocyt...

background: sildenafil citrate may increase endometrial thickness and affect the outcome of frozen-thawed embryo transfer cycles. objective: the aim of this study was to estimate the effect of sildenafil citrate on ultrasonographic endometrial thickness and pattern and to investigate the estrogen level on the day of progesterone administration, the implantation rate and chemical pregnancy rate ...

objective: in order to evaluate the endometrium by ultrasound in patients undergoing controlled ovarian hyperstimulation (coh) with clomiphene citrate (cc) and human menopausal gonadotropin (hmg) with intrauterine insemination (iui) to determine the relationship between endometrial pattern and thickness on pregnancy rate (pr). methods: in this prospective study, 108 infertile couples underwent ...

Background: Despite recent technical improvement in assisted reproductive techniques (ART), the implantation rate per embryo still remains low (15%). The aim of the study is to determine whether the failure of IVF cycle is associated with endometrial thickness on the day of HCG (human chorionic gonadotropin) administration. Materials and Methods: Endometrial thickness of two hundred and seven p...

results endometrial thickness in patients who had 0, 1, 2, 3 and 4 d&c; were 10.00 ± 0.58, 9.83 ± 0.47, 8.90 ± 0.92, 7.42 ± 0.18 and 7.40 ± 0.07, respectively one day before ovulation (spearman’s correlation coefficient = -0.33) and 10.62 ± 0.68, 9.64 ± 0.49, 8.48 ± 0.96, 6.32 ± 0.15 and 6.90 ± 0.04, respectively, 5-7 days after ovulation (spearman’s correlation coefficient = -0.66) estradiol a...

the success of oocyte donation is influenced by multiple factors. we performed a retrospective analysis to evaluate prognostic factors in oocyte donation cycles. the main outcome measurements including recipient age, donor age, estradiol level in midcycle, the day of transfer and number of transferred embryos were not different in pregnant and non pregnant groups. endometrial pattern but not en...

objective: the endometrial hyperplasia measured by ultrasound in polycystic ovary syndrome (pcos) women is strongly related to pathologic endometrial thickness, but there is no consensus on the relation between serum luteinizing hormone (lh) and either of these factors: pathologic endometrial hyperplasia and body mass index (bmi). materials and methods: in this observational cross-sectional stu...

BACKGROUND Sildenafil citrate may increase endometrial thickness and affect the outcome of frozen-thawed embryo transfer cycles. OBJECTIVE The aim of this study was to estimate the effect of sildenafil citrate on ultrasonographic endometrial thickness and pattern and to investigate the estrogen level on the day of progesterone administration, the implantation rate and chemical pregnancy rate ...

background: many studies have been carried out to understand the effect of endometrial thickness on the reproductive outcome while the factors affecting the pattern itself are still unknown. objective: to determine the factors such as age and the number of follicles that could affect the endometrial thickness materials and methods: this study was conducted as a retrospective study on 680 infert...
