Endometrial ultrasonography as a predictor of pregnancy in an in-vitro fertilization programme.

چکیده
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 were assessed with an Ultramark 4 (ATL) ultrasound equipped with a 5 MHz vaginal probe. Endometrial pattern I (a 'triple-line' multilayer) was observed in a total of 105 cycles (76%), and pattern II (fully homogeneous and hyperechogenic in relation to myometrial tissue) in 34 (24%). The incidence of clinical pregnancy did not differ (P = 0.52) between the groups with endometrial patterns I (23.8%) and II (29.4%). Endometrial thickness on the day of HCG administration in the group with pattern I (8.4 +/- 1.9 mm) was similar (P = 0.96) to that observed in the group with pattern II (8.4 +/- 2.0 mm). In addition, the endometrial thickness of the patients who became pregnant (8.0 +/- 1.7 mm) did not differ (P = 0.15) from that of women who did not achieve pregnancy (8.6 +/- 2.0 mm). The conclusion from the present data is that ultrasonographic analysis of endometrial thickness and refringency on the day of HCG administration had no predictive value for conception in IVF cycles.

Preliminary report of an ultrasonography and colour Doppler uterine score to predict uterine receptivity in an in-vitro fertilization programme.
A total of 96 women undergoing in-vitro fertilization (IVF) treatment were examined by transvaginal ultrasonography with colour and pulsed Doppler ultrasound on the 22nd day of the menstrual cycle preceding IVF. We assessed endometrial thickness, endometrial morphology, myometrial echogenicity, subendometrial vascularization, the uterine artery pulsatility index, protodiastolic notch and end di...
متن کاملI-45: Color Doppler Sonography of Endometrium in Infertility Patients
Background Endometrial receptivity is one of parameters which determine the reproductive outcome in in vitro fertilization programs. A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation. Blood vessels of the endometrium can be detected by transvaginal color and pulse Doppler sonography. Color Doppler assessment permits better visualiz...

This study was designed to investigate the role of three-dimensional (3D) endometrial ultrasound in predicting the outcome of an in-vitro fertilization (IVF) programme. In 47 IVF cycles measurements of endometrial thickness and volume, as assessed by 3D transvaginal ultrasound on the day of oocyte retrieval, and concentrations of oestradiol and progesterone in the same patient sampled on the da...

Ultrasound Assessment of Endometrial Receptivity in in vitro Fertilization Treatment
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...
