Registration of close family members of twins and higher-order multiples

Please use the family member registration link provided by the twin or higher-order multiple who has already registered with GERTRUD. This link was sent to them by email.

What can you expect during registration?

In the registration form, you will be asked to provide some personal information about yourself or your child (if you are the legal guardian of twins or higher-order multiples), including sex, age, and zygosity (that is, whether you are identical or fraternal, if known). You will also receive important information about data protection. Registration only takes a few minutes. You can find more details about the registration process here.

Your privacy is very important to us. If you have any further questions about how we process and protect your data, please refer to our privacy policy here or contact us at gertrud@mpib-berlin.mpg.de.
