Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will be provided with a link to the Victorian Assisted Reproductive Treatment Authority (VARTA) website and access to the online Egg Freezing decision aid (DA).

The Egg Freezing DA was developed by a working party that includes a team of experts in fertility, psychology, decision-making, women’s health as well as consumer representatives, and in accordance with the International Patient Decision Aid Standards (IPDAS). These standards are designed to enhance the quality and effectiveness of DAs. For example, by recommending that information about alternative options are sufficiently detailed, probable outcomes are unbiased and understandable, and information is presented in a structured and balanced manner. The DA aims to support the decision-making process of women considering egg freezing, by providing unbiased and evidence-based information about the process including its positive and negative aspects.

Content is delivered using informative text, animations and infographics.
Areas covered include:
• Common causes of female infertility.
• The relationship between female fertility and age.
• The benefits and uncertainties of egg freezing at different ages.
• The steps involved in egg freezing including potential risks, time commitment and costs.
• The variability and unpredictability of the number of eggs collected, and the potential need for multiple cycles to obtain goal eggs numbers.
• Personal stories from women who have considered egg freezing before.
• Variability of outcomes between clinics (generally), and legal limits for gamete storage.
• A values clarification exercise around reasons for freezing eggs.
• Circumstances in which frozen eggs might be used (including the use of donor sperm), and options of solo parenthood.
• Evidence about the outcome for children conceived using frozen eggs.
• Health, social and psychological implications of older age on pregnancy and child outcomes.

After completing the baseline survey, participants randomised to the intervention group will be emailed a link to the VARTA website and Egg Freezing DA. Participants will be told they can spend as much or as little time as they like reviewing the websites. Adherence will be monitored using website analytics and via self-report as part of the 6 and 12 month follow up surveys.

Behaviour
Comparator / control treatment
The control group will be provided with a link to the Victorian Assisted Reproductive Treatment Authority (VARTA) website.

Content relating to egg freezing includes:
- Reasons for freezing;
- Steps involved;
- Storage time;
- Success rates;
- Associated potential risks;
- Financial realities, and;
- Important questions to ask a doctor.

After completing the baseline survey, participants randomised to the control group will be emailed a link to the VARTA website. Participants will be told they can spend as much or as little time as they like reviewing the website. Adherence will be monitored via self-report as part of the 6 and 12 month follow up surveys.
