Power doppler ultrasound assessment of the relationship between age and ovarian perifollicular blood flow in women undergoing in vitro fertilization treatment.

Purpose: To examine the relationship between age and ovarian perifollicular blood flow (PFBF) in women undergoing IVF.

Methods: Serial transvaginal power Doppler ultrasound (PDU) scans to assess ovarian PFBF were performed prospectively throughout the follicular phase of ovarian stimulation in women undergoing IVF. The ultrasound assessment days were categorized according to day of hCG trigger.

Power Doppler ultrasound assessment of ovarian perifollicular blood flow in women with polycystic ovaries and normal ovaries during in vitro fertilization treatment.

Objective: To evaluate whether ovarian perifollicular blood flow (PFBF) varies by ultrasound among women with polycystic and normal ovaries undergoing in vitro fertilization (IVF).

Design: Prospective observational cohort study of women undergoing IVF treatment.

Setting: Department of reproductive medicine at a university teaching hospital.
