Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
PIEZO ICSI is an alternative ICSI method that utilises ultra-fast drilling coupled with a blunt-ended capillary to drill through the eggs membranes, without forced penetration. It is therefore, thought to be a more ‘gentle approach’ than conventional ICSI. No additional requirements outside of the patients standard assisted reproductive technology treatment will be required by participants. The intervention is administered ex-vivo (in the embryology laboratory) by the embryologist performing the insemination of sperm and eggs. Embryologist will monitor the development of the embryos through specific timed observations to ensure normal embryo growth following PIEZO ICSI.
Intervention code [1] 316834 0
Treatment: Devices
Comparator / control treatment
Conventional ICSI involves the use of a beveled spiked pipette to manually penetrate the egg’s plasma membrane with aspiration of the egg’s cytoplasm to activate the egg prior to injection of previously immobilised sperm.

Active

Intervention assignment
Other
Other design features
Sibling split model.
The number of eggs collected form the patient will be assessed for suitability for injection. If the patient has greater than or equal to 6 mature eggs for injection, their eggs will be split into two groups- conventional ICSI and PIEZO ICSI. In patients where odds numbers of eggs are collected, the larger numerical value after splitting into the two groups will always be inseminated by conventional ICSI. Eggs will be randomly assigned to each treatment arm based on the random order they are denuded. If a patient has less than 6 mature eggs for injection they will be unable to partake in the trial as this is insufficient number of eggs to draw adequate conclusions. All of their eggs will instead be inseminated via conventional ICSI.

Type of endpoint/s
Efficacy
Statistical methods / analysis
All categorical outcomes (i.e. fertilisation rate) will be analysed by a binomial regression, with patient and treatment group added as a fixed factor. Continuous data (i.e. embryo utilization) will be analysed by a paired samples T-test. The sibling split design allows for both across group (Piezo vs conventional ICSI) and within patient comparisons for stronger statistical outcomes.
