Thank you for expressing an interest in becoming a sperm donor. This leaflet is intended to give you information on how to prepare to become a donor. Further information regarding becoming a donor is available on our website.
The process of spermatogenesis (sperm production) is cyclical (happens in cycles) and takes approximately three months to complete. Therefore prior to and during the course of your donation you will be advised to maintain a healthy lifestyle to maximise your sperm quality.
This will include having a balanced, healthy diet and maintaining a healthy weight. Being overweight (BMI greater than 25) can have health implications and could cause a decline in sperm quality.
Some medications, supplements and drugs are not suitable to take when trying to have a baby and therefore they are also not suitable to take prior to sperm donation. Please inform our team of anything that you might be taking and seek advice from a GP or pharmacist before taking anything else as well as letting your GP be aware if they prescribe you any medications
Prior to each donation you will be asked to maintain an abstinence period of between 2 days (48 hours) and up to 5 days. If you have been unwell and have had a raised temperature in the last three months it is important that you let us know as this can affect the quality of your sperm sample.
Research suggests that people who smoke are less likely to conceive following IVF treatment. Therefore it would be beneficial for a donor to be a non-smoker. If you would like help to stop smoking please speak to the nurses who can offer you advice, or locate services near you.
The Department of Health now advises that people trying to conceive should avoid drinking alcohol excessively and therefore sperm donors should limit drinking alcohol during the course of donation. If you choose to drink alcohol then avoid drinking more than 14 units per week (approximately six pints of lager or one and a half bottles of wine) and spread this evenly over three or more days.
During the course of donation you will be advised to only have protected sex (for example use a barrier method such as a condom). This will avoid the risk of contracting a sexually transmitted infection (STI) during the course of donation.
If you are worried about this we encourage you to let us know. At each donation appointment we will ask if you’ve been knowingly exposed to, or been treated for, any STIs since your last visit. If you experience any potential symptoms of an STI at any time during the donation period please immediately tell us.
