About this trial
Infertile women attending for PGT at the Centre of Assisted Reproduction and Embryology, Queen Mary Hospital and Kwong Wah Hospital will be recruited during ovarian stimulation for IVF. Subsequently, they will be randomly assigned on the day of oocyte retrieval by a laboratory staff into one of the following two groups in a 1:1 ratio : (1) the microfluidic chip group and (2) the density gradient centrifugation group for sperm preparation and subsequent use in fertilization. Other IVF procedures will be the same as the standard practice of the Centre. Both women and clinicians will be blinded from the group allocation i.e. a double blind study.
