Due to the risks to egg quality caused by nicotine, smokers cannot be accepted as egg donors. When you apply to become an egg donor, we ask you if you smoke, and we will test your urine for nicotine at your appointments.

If you used to smoke or are trying to stop smoking, you must have no nicotine in your system for at least three months before your donation application. You should then be free from the effects of nicotine, including e-cigarettes, as they still contain nicotine.

No. In a donation cycle, we will collect all of the eggs that would have been lost naturally in that month, so this will not impact you later on in life or make you run out of eggs.

We take blood and urine samples to test for infectious diseases such as HIV, Hepatitis, and Chlamydia. We also check your chromosomes and test if you are a carrier of Cystic Fibrosis. We also carry out a transvaginal ultrasound scan to ensure that your ovaries and uterus are healthy and normal.

Drugs are taken in the form of daily injections. These drugs mimic the action of the body’s natural hormones.

Our team will discuss your options if this applies to you, we will always give you expert guidance and ensure that you are fully informed about your contraceptive choices.

All parts of the cycle are carried out on an outpatient basis, which does not require you to stay overnight.
