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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Swim-up (SU) and Density Gradient centrifugation (DGC) are both routinely used sperm preparation methods during IVF procedure. SU involves layering semen sample and culture media, and active swimming-up of sperm into the media phase so that sperm with good motility can be yielded. However there is a risk that seminal components migrate into the media which is believed to impact fertilisation and subsequent embryo growth. DGC involves centrifugations to force the motile sperm to go through density gradient media and then get separated. But centrifugations are proven to be harmful to sperm integrity and in turn affect fertilisation and subsequent embryo development. DGC is currently used as standard method for sperm preparation at Fertility North and will be used as control group. SU will be the treatment group.

Sibling oocytes collected from each participating patient will be randomly allocated into DGC (control) and SU (treatment) groups. Semen sample provided by the male partner will be split and go through different preparation methods separately. Oocytes in each group will be inseminated with sperm prepared by according method. After insemination, comparisons will be made on ferilisation rate, time post insemination to reach syngamy, 2,3,4,5,6,7,8-cell stages (t2,t3,t4,t5,t6,t7,t8)(hours), and implantation results after transfer of embryos. Only one-off intervention is involved at the sperm/egg level, none at the patient level.

Statistical methods / analysis
Data collected will udergo t-tests. so the number of participants was calculated via an on-line sample size calculator.

Fixed setting: Probability of Type I Error (a) = 0.05 &
Power (1 - B) = 0.8.
Regarding the (Difference to be detected) and (Within group SD), different values were used for different parameters. The final sample size (n=180 for each group) was determined by the biggest sample size required for any parameters to be assessed.
The average egg number collected per patient at Fertility North is 6, so the estimated number of participants is 60

Summary
Brief summary
Both Swim-up and Density gradient centrifugation are routine sperm preparation methods in IVF laboratory. However the content of seminal fluid might mix with separated sperm in the Swim-up method while centrifugation is involved in the other method which are both considered harmful to fertilisation and embryo development. The proposed study will use time-lapse technology to reveal the differeces in the subsequent embryo development.
