Antral follicle count in clinical practice: analyzing clinical relevance.

Objective: To determine the clinical relevance of obtaining antral follicle counts (AFC) before ovarian stimulation in an IVF program.

Design: Retrospective cohort study.

Setting: An IVF program in a large academic teaching hospital.

Influence of embryo transfer depth on in vitro fertilization and embryo transfer outcomes.

Objective: To investigate the influence of transfer distance from the fundus (TDF) on clinical pregnancy rate (PR) and ectopic pregnancy rate.

Design: Retrospective cohort. Between January 2000 and December 2001, 699 ultrasound (US)-guided embryo transfers were conducted.

Advancements in blood-compatible coatings.

Heparin-based coatings substantially improve the performance of a variety of blood-contacting medical devices. Recently, it has also been shown that nonheparin-based, synthetic coatings are promising for medical device applications where biological molecules are not desired or appropriate. This article reports on recent work.
