Sperm donor children and pregnancy quotas

How many children per donor?

In order to protect the privacy and rights of our donors and recipients we cannot answer the specific question of how many children have been reported per donor. 

Instead, we can state that it is Cryos' policy to follow any national limitation or national quotas. 

You can always check if a donor has reached the national quota under Donor Search.

How worried should I be about inadvertent consanguinity (also known as inbreeding)?

There is no reason to be concerned about the partnering of two donor conceived children from the same donor. The risk is extremely low, especially if the sperm bank distributes nationally and internationally, as Cryos does.

However, to get a better understanding of the risks, you should know more about consanguinity. Consanguinity, at it’s simplest, means that the DNA of the two parents is too identical. Recessive disorders in the DNA, which both the parents were only carriers of, can result in being passed on to the offspring and affect them. It is important to understand that we all carry plenty of recessive disorders in the DNA (C.J. Bell 2011) also the donors.

However, the risk may only increase by a few percent, in comparison to normal procreation. The larger problem of consanguinity arises if it continues generation after generation, as everybody sooner or later will be affected. This is seen for instance in very small and isolated communities or in royal families. This is not relevant for donors as it is only a one-generation issue.

To avoid or minimize the affects of consanguinity, small sperm banks servicing only a little community should only allow very few children per donor, but it can be up to 1 donor child for every 32,000 citizens if nationally or internationally distributed, according to the recommendation from the American Society of Reproductive Medicine (page 53). This goes to show that consanguinity is only a question about distribution and in fact, consanguinity by sperm donors is considered to be much less frequent than the general risk in the community (J.L. Serre, 2013).

To ensure geographical distribution, we follow to national and international quotas. You can always check if a donor has reached the national or the international quota under Donor Search when you click on "See details" of a specific donor. You can use the "Check pregnancy quota" function to get the right information.

What is a Quota Reservation?

A Quota Reservation is required in some countries to ensure that the limit of pregnancies by a donor is not exceeded. 

The Quota Reservation guarantees that you can use the donor during your entire treatment and for siblings even if local quotas have been reached since your initial purchase. Please remember to reserve straws for siblings.

To check if a Quota Reservation is required in your treatment country, please see Donor Search.

When and how should I report my pregnancy?

If you have become pregnant with the help of a Cryos donor, it is important that you report the pregnancy to us, so in the unlikely occurrence that your donor has a medical condition, we are able to contact you immediately.

We suggest reporting your pregnancy when you have passed the first trimester and before the birth of your child.

To report your pregnancy, please log in to your account on our website and go to the page ”Pregnancies”. Here you can register your pregnancy.

If you have had treatment in a clinic, you should report your pregnancy to both your clinic and to Cryos.
