Donating your sperm

Some patients can’t use their own sperm for fertility treatment.  

There are lots of reasons why our patients might need donor sperm, but with your help they might still have a chance of starting their family. If you’re considering becoming a sperm donor, we’d love to hear from you.  

Could sperm donation be for me?

We’re grateful to anyone interested in donating their sperm. To become a sperm donor, you just need to be between the ages of 18 and 45 and generally fit and healthy, with no known history of genetic disorders.

What does donating my sperm involve?

Medical assessment

If you decide you’d like to become a sperm donor, the first step is to call your nearest clinic. After you get in touch, we’ll ask you to fill out a detailed medical questionnaire before you meet a nurse from our donation team.

Your first visit

At your first appointment, we’ll go through the donation procedure with you in detail and conduct a semen analysis. We’ll also need you to produce a semen sample so that we can test how your sperm react to being frozen. Before this, and before any future samples, you should abstain from sex and masturbation for two to five days.

After sperm testing

Following analysis and results of your sperm test freeze/thaw, we’ll contact you to let you know whether or not you might be suitable as a sperm donor. We sometimes have to reject donors based on the survival rate of the sperm after the freeze/thaw process, which is usually around 50%; however, if this is the case this doesn’t reflect your own fertility.

Your second visit

If your initial test results look good, we’ll invite you for a second appointment and send you a detailed medical history form, which you’ll need to complete and return two weeks before this second meeting. When you come in for your appointment we’ll go through your medical questionnaire, conduct blood tests, urine tests and screenings, and ask you to complete the consent forms.  


At your second appointment, we’ll also offer you counselling. We believe all of our donors should have a session of counselling before they go through with donation; it’s an opportunity to talk about any ethical and legal issues, share any questions you might have, and make absolutely certain that it’s the right decision for you.  


Once we’ve got all your results, if we decide we’d like you to donate your sperm, we’ll invite you for a meeting with one of our consultants to confirm all the details. Then, we’ll ask you to make your donation once or twice a week for a period of around two months until we’ve collected and stored enough sperm. We usually ask for around eight donations, though this varies from donor to donor.

You can visit the clinic to make donations at any time during working hours, which are 8.30am to 4.30pm, Monday to Friday.

After donating

Our embryology team checks each donation before freezing and storing. A small volume is tested again to ensure the freeze was successful and that the sample’s suitable for storage.

Many men want to know what happens after their donation, we can let you know whether treatment is successful and how many babies are born, as well as their sex and their year of birth.


To thank you for your time and kindness, we’ll compensate you with £35 per donation visit. You’ll just need to fill out a form to claim reimbursement once you’ve completed your donations.
