Live-Birth Rate Associated With Repeat In Vitro Fertilization Treatment Cycles.

ABSTRACT:

Importance

The likelihood of achieving a live birth with repeat in vitro fertilization (IVF) is unclear, yet treatment is commonly limited to 3 or 4 embryo transfers.

Objective

To determine the live-birth rate per initiated ovarian stimulation IVF cycle and with repeated cycles.

Design, setting, and participants

Prospective study of 156,947 UK women who received 257,398 IVF ovarian stimulation cycles between 2003 and 2010 and were followed up until June 2012.

Exposures

In vitro fertilization, with a cycle defined as an episode of ovarian stimulation and all subsequent separate fresh and frozen embryo transfers.

Main outcomes and measures

Live-birth rate per IVF cycle and the cumulative live-birth rates across all cycles in all women and by age and treatm
