Primary Outcome Measures

Name	Time	Method
Pregnancy Rates (detection intrauterine gestational sac with foetal heart<br>beat at 7 weeks gestation)<br>[Detection of intrauterine gestational sac with foetal heart using ultrasound is conducted at 7-8 weeks gestation or 7-8 post embryo transfer. ];Live Birth Rates (delivery of a live infant showing any sign of life, for instance heartbeat and voluntary movement)[To determine whether or not a live birth has occurred, primary outcome [2] will be followed up from 9 months to 1 year after embryo transfer. This is due to the fact that after detection of a pregnancy, female patients come under the care of their selected obstetrician and selected maternity hospital. The timepoint described above allows adequate time for the return of clinical information about the live birth outcomes from the maternity hospital to the IVF clinic.]
