It's extremely unlikely that donating your eggs will have any negative effects on your own fertility.
In a normal donation cycle you'll only donate as many eggs as you'd lose naturally in that month, which is usually around 10 - that means you'll still have thousands of eggs left.
If you'd like to talk to one of our team about egg donation, you can book a consultation or call our enquiry team on 0800 564 2270 - they will be happy to answer any questions you have. Our teams are all very experienced in the egg donation process and you’ll be in good hands.
