Background: One of the most common causes of infertility in women is ovulatory dysfunction (PCOS) and the choice of treatment is clomiphene citrate. One of the mechanism of dichotomy between the rate of ovulation and pregnancy is anti estrogenic effects of clomiphene citrate on endometrium. According to its long half life, the anti estrogenic effects probably exacerbate in consecutive cycles. W...

The endometrial pattern and thickness were analysed by ultrasonography in 139 cycles stimulated for in-vitro fertilization (IVF) on the day of administration of human chorionic gonadotrophin (HCG). A semi-programmed schedule based on the pill + clomiphene citrate + human menopausal gonadotrophin (HMG) was used in all cycles. On the day of HCG administration, endometrial pattern and thickness we...

OBJECTIVE To evaluate the combined effect of endometrial thickness and pattern on clinical outcome in patients undergoing in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET). METHODS Cycles of IVF/ICSI-ET conducted between January 2003 and December 2008 at a university-based reproductive center were reviewed retrospectively. Endometrial ultrasonographic c...

Ultrasonography of the endometrium is a noninvasive way to evaluate the chance of successful implantation during in vitro fertilization treatment. Ultrasound parameters of endometrial receptivity include endometrial thickness, endometrial pattern, endometrial volume, Doppler studies of uterine vessels and the endometrium. Endometrial thickness, pattern and volume are not predictive of pregnancy...

BACKGROUND Endometrium remains the most sensitive indicator of ovarian function and endometrial biopsy is one of the diagnostic procedures in endometrial pathology. The current study was carried out to examine the morphological pattern of endometrial biopsies in Ibadan, South-western Nigeria and compare the results with similar studies. METHOD A retrospective study was undertaken to review al...

BACKGROUND A good blood supply to the endometrium is usually considered as an essential requirement for implantation. OBJECTIVE The aim of this study was to evaluate the role of endometrial and subendometrial vascularity in the prediction of pregnancy during frozen-thawed embryo transfer (FET) cycles. METHODS Women undergoing FET in natural or clomiphene-induced cycles after the first stimu...

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...

ndometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity . the aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness in uterine receptivity in infertile women treated with assisted reproductive technologies (art). a...

The pattern of constitutive and cycle-dependent integrins in normal endometrium has recently been established, suggesting a role for cell adhesion molecules in endometrial receptivity and implantation. Currently few, if any, models exist for the study of human endometrial integrins and their role in establishment of the receptive endometrial phenotype. The Ishikawa cell line maintains functiona...

objective: to assess follicular development and endometrial growth using transvaginal sonography in spontaneous and clomiphene citrate induced (cc) cycles. materials and methods: one hundred consecutive couples with unexplained infertility were recruited for this cross sectional study from 2003 to 2005. patients were monitored for the first cycle with no medication while the laboratory routine ...
