3/15: UK twin sudy shows autism "largely genetic".   A UK twin study estimates that between 56 and 95 percent of autism spectrum disorder (ASD) cases are attributable to genetics.

The findings, published in JAMA Psychiatry, suggest that the risk of ASD and related traits is more strongly influenced by genetics than previously thought.

'These results further demonstrate the importance of genetic effects on ASD, despite the dramatic increase in prevalence of the disorder over the last 20 years,' explained study author Beata Tick from the Kings College London team.

6/13 Flanders News: Danish sperm donor also passed on genetic disorder in Belgium (pdf)
Nordisck Cryobank's donor 7042 has passed along the rare NF1 genetic disorder to offspring.  Of the 43 children in 10 countries conceived with the help of the defective sperm, 9 have the disease (also known as Von Recklinghausen's disease), and 2 of those are in Belgium. NF1 is a rare genetic disorder affecting neurologic functions in humans.

5/13 NYU Interventional: Donor children live in ignorance of their father's illness (pdf)
Cryos in Denmark has been criticized by the National Board of Health for not adhering to the recommendation of 25 pregnancies per donor when it was discovered that 64 children may have inherited a rare disorder from their biological father, Donor 45.

3/13 Copenhagen Post: Sperm donor with genetic illness speaks out (pdf)
The Danish government health agency has been criticised for not looking for children who may have been born with a cancer-causing illness, Lynch Syndrome, inherited from an anonymous sperm donor. Even though the mortality rate can be significantly reduced with early treatment and diagnosis, the health authorities have decided not to search for the five to ten children who may have inherited the disease.

1/13 Readers Digest: Can you Inherit your Mother's Health? (pdf)
Many aspects of our health are genetically linked. According to researchers from the Institute of Cancer Research at the University of London, there's a 57 percent chance that a girl will start menstruating within three months of the date that her (biological) mother began. Here are 9 other women’s health conditions that experts say we may have inherited from our (biological) mothers...

11/12 America Now: Rolling genetic dice with a donor (pdf
Some ART facilities screen for some diseases, but few screen for potential genetically-inherited conditions.  This article talks about the repercussions when thorough screening hasn’t happened, and gives a synopsis of a few other articles on the same topic.  

9/12 BBC News: Denmark tightens sperm donor law after NF1 transmissions (pdf)
Due to a sperm donor passing along NF1, a rare genetic condition which affects the nervous system (and is untreatable), Denmark has passed new restrictions on Danish sperm bank operations, including limiting the number of offspring to 12 per donor.

9/12 Daily Mail: Danish sperm donor passes rare genetic disorder (pdf)
These two articles published 9/12 are referencing an earlier story, originally reported by DSR members (see the 5/11 Copenhagen Post article below).  The interesting thing about this story is that this donor is also a California Cryobank donor. We regularly hear stories about sperm donors passing along medical and genetic issues to children here in the US, but no regulation is ever initiated.

5/12 The New York Times: In Sperm Banks, a Matrix of Untested Genetic Disease (pdf)
The case of a child with cystic fibrosis, which was genetically linked to the donor used to conceive him, highlights the need for more regulation of the sperm bank industry, specifically around the genetic testing of sperm by cryobanks.  In this case, the sperm had been purchased from New England Cryogenic Center (NECC) who had purchased it from a bank that is no longer in business, and was at least 20 years old.

2/12 CBS: Parents Sue Cryogenic Center Over Child’s Cystic Fibrosis (pdf) (video)
This CBS report of the lawsuit brought against New England Cryogenic Center exposes that the sperm bank has faced very little oversight in its 30-year history.  It also points out that New York will not allow sale of NECC’s sperm donated at and purchased from another defunct cryobank. It is reported that NECC in initiated internal regulations surrounding that restriction, but did not remove that donor from their catalog.

7/11 Sperm Donor's 24 Kids Never Told About Fatal Illness (pdf) (video)
This article addresses the question of what regulation should be in place to protect children from conditions passed along by a donor, when a donor is not required to update the sperm bank where he donated.  The donor in question had surgery for Marfan’s Syndrome and an aortic defect, the same potentially-fatal heart condition that he passed on to at least one of his (at least) 24 offspring, who each have a 50% chance of having contracted the disease.  

6/11 Infertility & Reproductive News: Gamete Donation: Medical and Genetic Implications (pdf)

The Washington Times reports on the JAMA study of a man who passed HCM to his offspring via sperm donation.

11/09 BioNews: Sperm donor screening needs to be overhauled (pdf)
The DSR campaigns for more rigorous testing of sperm and egg donors for genetic diseases, and advocates the use of a monitored delay in the release of donor sperm to reassure users of its safety, and to track and limit the number of offspring from each donor.

11/09 The Washington Times: Doctor blames profit motive for sperm-donor diseases (pdf)
An interview with former DSR Board of Directors Chair, Kirk Maxey, discussing the lack of required testing of donated sperm.

5/09 BioNews: The case for comprehensive medical testing of gamete donors (pdf)
The DSR calls for mandatory genetic testing of egg and sperm donors.

4/08 O Magazine: The Children of Donor X (pdf)
Oprah's magazine follows the stories of several families who used the same anonymous sperm donor from California Cryobank. All of them are navigating medical issues that they attribute to genetic defects from the sperm donor.

10/06 Self Magazine: The Truth About Donor 1084 (pdf)
Self reports on Fairfax Cryobank donor 1084, and the medical issues he passed along to several offspring.  The story highlights the frustration of the families, who feel the sperm bank should have been more responsive to their concerns.


Other Reported Health and Genetic Issues

  • 2016: "...the only way we found about a serious genetic eye condition was because we had already found a large group of donor siblings and upon joining the group, the parent of the child with the condition contacted me and told explained the condition and the importance of having my son screened no later than 3 years of age. It is a very rare but treatable condition. It turned out my son has this condition and had we not had that info my son would most likely ended up having serious vision problems due to it being caught too late. The bank we used had this information but it was not shared supposedly because only one donor sib at the time had it and there was only a 12.5% chance that other donor sibs would have it...regardless, the info to have my son screened, saved his vision and I will forever be grateful that I have the connection I have with the 12 other donor sib families!"

  • 2016: "I am "donor" conceived. I just found out who my bio father was. Sadly, he died 7 months ago from stage 4 renal cancer. He was only 49 years old.  Also, there is some bad history of suicide and bipolar disorder in his family. I called the cryobank, Reproductive Resources in Metairie, LA. I told them his medical information and that they must immediately inform all other offspring of this information. They said they couldn't do that. What can I do? This could be a life or death situation. To withhold this information is unethical and criminal."

  • 2015: "I am an ovum donor and I have Ehlers-Danlos Syndrome types 2 and 3, and my two children do as well. This was only discovered in my 30s. I so wish I could tell other offspring."  If you have the most common varieties of Ehlers-Danlos syndrome, there's a 50 percent chance that you'll pass on the gene to each of your children.- Mayo Clinic

  • 2015:  A mom with a very sick child who used California Cryobank: "I contacted CCB and they were adamant about not contacting the donor or providing me with information about him, going as far as saying that they discouraged contact among donor families and refusing to recommend the Donor Sibling Registry (DSR) to a donor..".  Her full story.

  • 2015: ".. one of my children was diagnosed with a rare and severe type of Lymphoma/Leukemia (Precursor T-cell Lymphoma/Leukemia), which spread over his neck, throat, lungs, heart, inguinal area, blood and bone marrow.  He has been receiving intense chemo therapies."

  • 2014:  "My children have a disease called cavernous malformation disease: gene is called CCM1 (this is what all his offspring & he should be tested for). All three who have it, have active brain bleeds, and my 8 year old has had 2 strokes, now has epilepsy from the brain damage, and one child is expected to go blind eventually. Many people live like a ticking time bomb and never know what they have with this condition so I want other families to know!  Some don't get it, some are asymptomatic, BUT if they get help at a young age it could make the difference between life and death.

    I do not have it, so all our geneticists and teams of doctors have concluded it is from this donor.  He in fact deserves to know he has it, even if he has no active issues.

    I just want families of California Cryobank donor 3541 to know what their children may have it, or it may be an answer to some of them who are struggling for knowledge like we did for 2 years! It may help us as well to see if any sibs have it, and where/how they are progressing!"

  • 2014:  "I am the parent of two children who were born with a sperm donor.  They are both in their early 30′s.  In the past 6 weeks we have discovered that they were born with a bad gene and they have a rare heart disease.   With this gene,  a person just drops dead with no warning.   In checking my grandchildren, two of them, under the age of 10, carry the gene.  My oldest child and the youngest grandchild have had surgery.   My younger child is going to have a baby in December and that grandchild will have a 50 percent chance of getting the disease.  Still testing etc to see what that treatment will be.  I have had DNA testing done and I do not carry the gene.  Doctors said it had to come from the donor."

Medical Updates

Currently, many US facilities either refuse to update donor/offspring medical information or, even if they accept updates, refuse to share the information. Or they make the process of reporting so complex and expensive that donors and recipients simply cannot comply or afford it. In addition, US sperm banks do not have an accurate accounting of all children born from any one donor, so if illness is reported, it is then impossible to notify all potentially affected families.

  • 84% of sperm donors have never been contacted by their clinic(s) for medical updates.
  • 96% of egg donors have never been contacted by their clinic(s) for medical updates.
  • 23% of sperm donors felt that they had medical/genetic issues that would be important to share with families.
  • 31% of egg donors felt they had medical/genetic issues that would be important to share with families.
  • 94% of sperm donors would have accepted an offer for genetic testing, had it had been offered by their sperm banks.
