We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Sibling oocytes collected from each participating patient will be randomly allocated into the polyvinylpyrrolidone (PVP) (control) and hyaluronan (HA) (treatment) groups. Oocytes will undergo intracytoplasmic sperm injection (ICSI) with different handling medium in each group accordingly. Subsequent embryo culture condition is identical for both groups.
Intervention code [1] 287778 0
Treatment: Other
Comparator / control treatment
This is an auto-controlled sibling oocyte study. One of the 2 equally divided groups will work as the control (PVP) while the other group as treatment group (HA).

Primary outcome [2] 290286 0
Time post ICSI insemination to reach syngamy, 2,3,4,5,6,7,8-cell stages (t2,t3,t4,t5,t6,t7,t8)(hours)

Embryoscope is a time-lapse photographing incubator providing accurate timings for biological events during embryo development. Timings for syngamy and t2,t3,t4,t5,t6,t7,t8 of embryos cultured in the Embryoscope will be automatically recorded .

Secondary outcome [1] 304243 0
Embryo implantation rate (%) after transfer

Implantation is confirmed by detection of fetal heart beat under ultrasound 5 weeks after oocyte pick-up.

Implantation rate (%) = (number of fetal heart beat detected)/(number of embryo transferred) x 100%

Brief summary
Polyvinylpyrrolidone (PVP) has been routinely used in the intracytoplasmic sperm injection procedures to facilitate sperm handling for years although it's not degradable by the egg. Hyaluronan is a new alternative to PVP with all the features that PVP has and it's degradable by the egg. The proposed study aims at comparing the embryonic effect between these 2 reagents by using time-lapse analysis.
