From sperm donor to ‘Dad’: When strangers with shared DNA become a family

The Danish sperm donor number has fathered several offspring with neurofibromatosis type 1 NF1 worldwide. NF1 is caused by loss-of-function mutations in the NF1 gene and more than NF1 mutations are identified. Analysis of the donor sperm demonstrated gonosomal mosaicism with an intragenic deletion involving exons in the NF1 gene. At the two Danish reference centres for NF1 patients, we evaluated 23 half-siblings from the donor. Nine were diagnosed with NF1. The NF1 phenotype shows great variability in intra- and inter-family expressivity and to date only two NF1 genotype-phenotype correlations have been established. This rare possibility of a long-term follow-up of a cohort of half-siblings with NF1 makes further studies including phenotypic variability and search for modifier genes possible. Research facilitated via this registry may reveal important new knowledge of clinical characteristics and prognostics for the specific NF1 genotype and thereby contribute to future individualised targeted clinical follow-up and treatment.

They shared a lot in common, approximately 25 percent of their DNA. Jenny and Amanda were half-sisters and about to meet each other for the first time. Jenny and Amanda were born and raised just 20 miles from each other — Jenny in Boulder and Amanda in Westminster — but the sisters were conceived via sperm donation and neither knew the other existed for most of their lives. Nor did she know the brother with whom she had grown up was also conceived with an anonymous donor.

She was shocked — Jenny had never questioned the idea that the man who raised her was her biological father, nor that her brother was her full sibling. The hits kept coming. So Jenny ordered her kit, sent her DNA sample and impatiently waited for more than a month. She was curious about her ethnicity, and if she had any more siblings.

However, the growth of DNA databases like Ancestry. And because so much DNA information is being put into these databases, anonymous sperm donors are even being identified in some cases. Though the issue of sperm-donor anonymity has raised ethical questions in the donor conception industry for a while, DeCamp says at-home DNA testing has made the debate more public and relevant to a wider audience. The first successful conception using frozen sperm was reported in , ushering in a boom of sperm banks by the s.

Every year there are an estimated 30, to 60, donor-conceived babies born in the U.

New Show: Kids Find Their Sperm Donor! No Joke.

In NSW there are babies born every year who were conceived as a result of assisted reproductive technology treatment using donated gametes either as sperm, eggs or embryos created from donated gametes. Prior to the commencement of the Assisted Reproductive Technology Act ART Act on 1 January there was no process to support the disclosure of information about the people involved in this process.

This has meant that many individuals who were born as a result of ART treatment using donated gametes have been unable to identify a biological parent or obtain information about their genetic heritage and background, which has been distressing for some and occasionally created medical and social dilemmas. The ART Act established the Central Register to support information about donor conceived people, donors of gametes, parents and siblings of children who are donor conceived and those born through surrogacy arrangements, and to give donors and donor offspring greater opportunity to access information about each other.

Accidental incest is sexual activity or marriage between persons who were unaware of a family Some jurisdictions permit offspring of IVF donations access to donation fertility clinics usually limit the number of times that a donor’s sperm may be In , it was reported that a British brother and sister, who were twins​.

It is hard to think of a code of behaviour which is common to all societies on earth, let alone to most other species too — except, that is, for the avoidance of incest. Even cockroaches have developed a breeding strategy that prevents them mating with their own siblings. And yet as we understand more about the genetic dangers of inbreeding, so the social infrastructure that guards against it is being dismantled.

And yet there is virtually no guard against the children growing up and accidentally breeding with half-brothers and sisters of whose existence they are unaware. The failure to develop such safeguards is serious because the risks of genetic abnormalities from incestuous conceptions are so high. In the Czechoslovakian Academy of Sciences studied children born in such relationships and found that more than half had some kind of health problem, while 42 per cent had severe birth defects and 11 per cent were mentally impaired.

There has always been a risk of brothers and sisters beginning relationships unaware that they are siblings — or more likely half-siblings. Children born as the result of affairs may have no inkling of who their real father is. A geneticist who works in a west London hospital told me that in as many as one in ten cases of children investigated for various reasons there is no genetic match between the child and the man who thinks he is the father.

But that is a risk which is hard for government to guard against. The increasing number of children who are conceived with donor eggs or donor sperm — an activity that is regulated by the state — is quite another matter. Some sperm donors are remarkably prolific: it recently emerged that there are 17 men who have each fathered at least 30 children via donating their sperm and a further with between 20 and 29 children. There is a limit in Britain: sperm donors are supposed to donate sperm to a maximum of ten families.

Since he was born , Tylen has known he had a half brother on the other side of the country. The kids were born weeks apart, met as infants, and played together. Their single mothers spoke weekly on the phone and raised them as half siblings so they would always have someone just like them whom they could turn to.

Analysis of the donor sperm demonstrated gonosomal mosaicism with an and to date only two NF1 genotype-phenotype correlations have been established.

Jamie Larson is a designer, educator, and activist who resides in Brooklyn NY. She was conceived via anonymous fresh sperm donation in in Chicago IL. As a 2nd Generation queer woman with a plethora of lesbian parents, Jamie is a steadfast advocate for the ethical inclusion and representation of our queerspawn identities and queer heritage.

She is the co-founder and co-director of the Queerspawn Resource Project queerspawnresource. Lilly T-B is a sophomore in high school as well as a climate justice and reproductive rights activist living in New Hampshire. She was conceived through anonymous sperm donation, and lives with her multiple mothers. Lilly has been inspired by the pride of her mothers and family, and works continuously with various campaigns throughout the country to elect the right candidates into office, and to push the envelope for issues that matter to her.

She was raised with two half siblings, each with their own anonymous donor. Still in her youth, she has only recently begun to take pride in her identity as second generation queerspawn. Emily: When my mom decided to become pregnant, there were a few sperm banks and doctors that would work with lesbians and single women. She chose a local clinic that used fresh sperm from local donors, so not frozen or stored.

Inside the Secret Sisterhood of Women Who Share a Sperm Donor

Accidental incest is sexual activity or marriage between persons who were unaware of a family relationship between them which would be considered incestuous. The laws of many jurisdictions void incestuous marriages , even if entered into without awareness of the kinship. If an incestuous relationship is suspected, DNA testing may be used. Some jurisdictions permit offspring of IVF donations access to donation records or to adoption records.

People may be unaware of a kinship relationship between them in a number of circumstances.

I always knew I was conceived using a sperm donor. and my mom said to my brother and me, ”When you’re dating, you’ll have to be careful.

The author and her half-sister Eve left meet their half-sister Charlotte right. All photos courtesy of the author. If you met me and asked one of those routine introductory questions—where I grew up, if I have any siblings—I would probably tell you I’m an only child. Technically, though, I also have 17 brothers and sisters, and counting. Let me explain. I was conceived by a sperm donor. My mom never had a hard time with men, but when she found herself single at 40, she decided it was time to fulfill her lifelong dream of having a child—even if it meant doing it on her own.

She paged through a huge binder of sperm donors at the California Cryobank and quickly made her choice: He was healthy, tall, athletic, and creative. This man would be my dad. From the very beginning, my mom was very honest with me about where I came from. Some parents tell their kids that babies come from “two people who love each other very much.

While I didn’t know much about my dad, I would sometimes flip through the donor binder that my mom kept in a big, brown cabinet in our living room. The description of my donor was short but informative: He had curly brown hair, was on the track team, liked to make art.

Accidental incest

This information was never kept from us, and my mother has spoken openly about it throughout our lives. My stepdad adopted us. Recently, I was discussing taking an ancestry test and my mother revealed to me her sister and my uncle had troubling conceiving, and my cousin is also a sperm-donor child. They, however, have not disclosed this to her; my uncle was the source of infertility and did not want her to know he has some ego issues.

To date, the Donor Sibling Registry has helped to connect more than 13, half-​siblings. The author (right) with her half-siblings Gus and Macy.

The decision to use a sperm donor to have children is not one that anyone takes lightly. If treatment is successful, it is also the start of a new and lifelong journey for you and your family. There are many issues to weigh up, some logistical, some financial, some medical and, of course, some emotional. Going through treatment can itself be a stressful time for you and your partner if you have a partner.

At this stage, it can be tempting for everyone to focus on getting pregnant, but it is important to consider the longer-term aspects of using a sperm donor. Bear in mind that hopefully, you will have a child and that they will grow up to be an adult and perhaps have a family of their own one day. An Non-ID-Release donor is someone whose identity, for instance, their name and address, will not be released to you or your child by the authorities involved including the clinic where you were treated.

Donor-conceived children looking for their sperm donor: what do they want to know?

When Peter Ellenstein goes out to dinner with his children, who range in age from 17 to 30, the meals are raucous, and there is always a lot of catching up to do — especially because no one in the family knew each other before last October. Ellenstein, 57, donated sperm anonymously in his 20s and early 30s to make some extra cash, and never expected to meet any of his offspring. But this past year, thanks to online tools, including DNA test kits, he discovered that he has at least 24 biological children.

A divorced theater director living in Los Angeles who never raised any kids of his own, Ellenstein has met 20 of them so far. Fearing the interactions might be awkward or disappointing, he was initially reluctant to meet his children.

All of them came from the same sperm donor. And pictures of Kianni Arroyo’s siblings grace her Donor Siblings Ruth Arroyo’s family even considered the possibility of Kianni Arroyo dating someone related to her, and.

Nelson Author Rosanna Hertz Author. Description The ready availability of donated sperm and eggs has made possible an entirely new form of family. Children of the same donor and their families, with the help of the internet, can now locate each other and make contact. Sometimes this network of families form meaningful connections that blossom into longstanding groups, and close friendships. This book is about unprecedented families that have grown up at the intersection of new reproductive technologies, social media and the human desire for belonging.

Random Families asks: Do shared genes make you a family? What do couples do when they discover that their children shares half their DNA with a dozen or more other offspring from the same sperm donor? What do kids find in common with their donor siblings? What becomes of these chance networks once parents and donor siblings find one another? Based on over interviews with children ages and their parents from all over the U. Children reveal their understanding of a donor, the donor’s spot on the family tree and the meaning of their donor siblings.

Through rich first-person accounts of network membership, the book illustrates how these extraordinary relationships — woven from bits of online information and shared genetic ties — are transformed into new possibilities for kinship. Random Families offers down-to-earth stories from real families to highlight just how truly distinctive these contemporary new forms of family are.
