"Those advocating and recommending unproven procedures to their patients must ensure that they fully inform the patient of the evidence for its safety and effectiveness orally and in writing to ensure that people considering treatment using adjunct therapies are in a position to make an informed decision. It is also important that all procedures performed, including the adjunct treatments, are well-documented and followed up."
The unproven treatments described in the paper include:
Embryo glue Sperm DNA fragmentation Time-lapse imaging Preimplantation genetic screening Mitochondria DNA load measurement Assisted hatching
The problem is that most IVF clinics are private, for-profit businesses, which are happy to exploit their patient's ignorance. This is why they merrily continue to offer expensive , unproven treatment options, in order to maximise their profits.
If your doctor prescribes these " treatments" , without telling you they are experimental and unproven, then he is using you as a guinea pig. If you don't want to pay for the privilege of being one, then you should refuse these.
