The ORT test is the initial infertility investigation performed by the CRGH when considering IVF/ICSI treatment. This test takes place on Day 2, 3 or Day 4 of the period and involves a vaginal scan, a blood test, stimulating injection and then a repeat blood test the following day to determine hormone changes.
The ORT test is used:-
- clinically as a guide for determining the optimal dose of fertility drugs for individual women undergoing IVF treatment
- to identify excessive responders and therefore reduce the risk of hyperstimulation
- to identify poor responders and therefore reduce cancellation rate
- for women with a sub-optimal result it is important for them to know that they are not necessarily infertile, however adjustments may have to be made to their ovarian stimulation regime to compensate for a diminished ovarian reserve
- as a prognostic factor for the treatment of subfertile couples
