Study information
Scientific title
The use of near infrared (NIR) spectroscopy of culture media from human embryos to predict the embryos reproductive potential: a double-blinded randomised controlled trial
Acronym
Study hypothesis
To find out if near infrared (NIR) spectroscopy of culture media from human embryos combined with morphology better predict an embryos reproductive potential than embryo morphology alone.
Ethics approval
Local ethics committee (Regionala Etikprövningsnamnden i Göteborg) approved on the 25th March 2008 (ref: 120-08)

Double-blinded single centre randomised controlled trial

Condition
Infertility
Intervention
1. Intervention arm: Embryos for transfer will be chosen by performing a morphological evaluation of the embryos and an analysis of the culture media by NIR
2. Control arm: Embryos for transfer will be chosen solely based on morphology
The duration of the "treatment" is 30 minutes per couple. The total follow-up time is 7 weeks after embryo transfer per patient.

Primary outcome measures
Number of ongoing pregnancies per randomised patient (intention to treat), based on fetal heart activity by means of ultrasound 45 days after embryo transfer.
Secondary outcome measures
1. Total number of positive pregnancy tests per randomised patient, 18 days after embryo test
2. Number on ongoing pregnancies per randomised patient, based on fetal heart activity by means of ultrasound 45 days after embryo transfer on day 2
3. Number on ongoing pregnancies per randomised patient, based on fetal heart activity by means of ultrasound 45 days after embryo transfer on day 5
4. Number of ongoing pregnancies per embryo randomised patient, where only those embryos reaching the threshold level of viability from the NIR analysis will be included
