Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Feasibility and supply of high-quality eggs from this source to support current and future research grant applications assessed from egg numbers received measured using clinical records at the time of egg collection for each patient, research projects undertaken measured using publication records and degree completions at the study end date, and grant applications received measured using financial records at the study end date | — |
Secondary
| Measure | Time frame |
|---|---|
| Pregnancy occurrence and outcome in participants following IVF treatment, assessed from clinical follow-up at the end of the patient’s treatment cycle (pregnancy test), live birth (at approximately 9 months after the end of the treatment cycle), and the study end date | — |
