Conditions

In vitro fertilization (IVF), infertility, miscarriage, chromosomal anomalies arising in female meiosis such as Trisomy 21 Down syndrome, mosaicism Other In vitro fertilization

Interventions

Patients taking part in this study are undergoing a cycle of IVF treatment. If they participate in the study, they agree to provide half of the eggs that they produce to a research project, while the

No large endometriotic ovarian cysts >3 cm 5. Body mass index between 19 and 30 kg/m² 6. Completed donor screening (transmissible diseases excluded, cytogenetic testing, and no family history of inherited disease) 7. No previous evidence of poor ovarian response 8.

No evidence of adverse embryology in previous cycle (e.g. poor embryo or oocyte quality)

Exclusion criteria

Exclusion criteria: The exclusion criteria are the same as those applied clinically for patients sharing eggs with another person/couple. 1. Not in the required age range or BMI range 2. History of previous poor ovarian response or evidence of low ovarian reserve 3. Previous pregnancy loss due to fetal abnormality 4. Family history of inherited disease 5. Positive test results for viral risks (Human Immunodeficiency Virus [HIV], Hepatitis B, Hepatitis C, or Zika virus) or transmissible diseases 6. Medical contraindication to ovarian stimulation or oocyte recovery 7. Hydrosalpinges or large endometriotic ovarian cysts 8. Previous history of adverse embryology 9.

Design outcomes

Primary

MeasureTime 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

MeasureTime 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
