Donated eggs can come from our egg-sharing programme or altruistic donors, or from a known donor.
Reasons for needing to use donated eggs include:
- premature menopause – this affects 1-2% of women under 40
- the ovaries have been damaged by chemotherapy or radiotherapy treatment for cancer
- a lack of functioning ovaries (for instance, Turner’s syndrome)
- stimulation-resistant ovaries
- a high risk of a genetic disorder being passed on to children
- poorly functioning ovaries as a result of age
Donated eggs are fertilised using sperm from the male partner, or from donated sperm, and the resulting embryos transferred to the woman’s womb. The woman carrying the pregnancy will have treatment to prepare her uterus for the embryo transfer.
