The use of real time strain endometrial elastosonography plus endometrial thickness and vascularization flow index to predict endometrial receptivity in IVF treatments: a pilot study.

Background: The usefulness of endometrium strain elastosonography (SE) for the evaluation of endometrial receptivity in women undergoing in vitro fertilization (IVF) remains controversial. The objective of this prospective, observational study was to evaluate the correlation between endometrial thickness (EMT) and its related strain (ESR) on the day of ovulation triggering (hCG-d) and in vitro fertilization outcomes. Additionally, 3D Power Doppler vascular indices (3DPDVI) were also analysed.

Basal FSH concentration as a predictor of IVF outcome in older women undergoing stimulation with GnRH antagonist.

The aim of this study was to determine the value of basal FSH as a predictor of assisted reproduction outcome in women >or=35 years undergoing ovarian stimulation with gonadotrophin-releasing hormone (GnRH) antagonist. A retrospective clinical study was carried out on 83 infertile women, 35-45 years old, divided into three groups according to their day 3 FSH concentration (group A = FSH 10 and <15 mIU/ml, group C = FSH >15 mIU/ml). Patients underwent ovarian stimulation with a GnRH-antagonist protocol.

A novel protocol of ovulation induction with delayed gonadotropin-releasing hormone antagonist administration combined with high-dose recombinant follicle-stimulating hormone and clomiphene citrate for poor responders and women over 35 years.

Objective: To evaluate the efficacy of a novel protocol of ovulation induction for poor responders.

Design: Prospective, controlled, clinical study.

Setting: Research institute's reproductive unit.
