'I know it's not normal but it's normal to me, and that's all that matters': experiences of young adults conceived through egg donation, sperm donation, and surrogacy

STUDY QUESTION

What are thoughts and feelings of young adults born following egg donation, sperm donation, and surrogacy?

SUMMARY ANSWER

Young adults felt either unconcerned or positive about the method of their conception.

WHAT IS KNOWN ALREADY

Much of what we know about adults born to heterosexual couples following anonymous donation has come from samples of donor conceived people who had found out about their origins during adulthood. There have been no studies of how young adults born through surrogacy feel about their conception and towards their surrogate.

STUDY DESIGN, SIZE, DURATION

Thirty-five young adults were interviewed as part of the seventh phase of a larger multi-method, multi-informant longitudinal study of assisted conception families in the UK. Adults were conceived using either egg donation, sperm donation, gestational surrogacy, or genetic surrogacy and were raised in households headed by heterosexual couples.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants had a mean age of 20 years and were born following traditional surrogacy (n = 10), gestational surrogacy (n = 5), egg donation (n = 11), or sperm donation (n = 9). All young adults born following sperm donation and most (n = 10) born from egg donation had an anonymous donor. In all surrogacy arrangements, the parents had met the surrogate prior to treatment. The majority of young adults were told about their conception by the age of 4 years. Participants were interviewed over the internet using a semi-structured interview. Interviews were transcribed verbatim and analysed using qualitative content analysis to understand young adults' thoughts and experiences related to their conception and whether they were interested in meeting their donor or surrogate.

MAIN RESULTS AND THE ROLE OF CHANCE

Fourteen (40%) young adults felt their conception made them feel special or unique, with the remainder feeling either neutral or unconcerned (n = 21, 60%). A higher proportion of young adults conceived using egg donation (n = 8, 73%) felt unique/special compared to young adults born following sperm donation and surrogacy. For 10 of the young adults, their feelings about their conception had changed over time, with most becoming more positive (n = 9, 26%). For most young adults (n = 22, 63%), conception was rarely or infrequently discussed with others. However, when it was, these conversations were largely conducted with ease. Most (n = 25, 71%) did not know other individuals born through the same method of conception as themselves, and the vast majority (n = 34, 97%) were not members of any support groups. For the 25 young adults not in contact with their donor or surrogate, 11 wished to meet them, 8 did not want to have contact, and 6 were unsure. Young adults in contact with their donor or surrogate had varying levels of closeness to them. Only one young adult had searched for the identity of their donor.

LIMITATIONS, REASONS FOR CAUTION

Of the 47 young adults invited to participate in the present study, 35 agreed to take part resulting in a response rate of 74%. It is therefore not known how those who did not take part felt about their conception. Given that the families reported here had been taking part in this longitudinal study from when the target child was aged 1 year, they may have been more likely to discuss the child's conception than other families. The study also utilized self-report measures, which may have been prone to social desirability, with donor conceived young adults wanting to present their experiences in a positive light.

WIDER IMPLICATIONS OF THE FINDINGS

The findings suggest that young adults born through surrogacy and donor conception do not feel negatively about their birth and this may be a consequence of the young age at which they found out about their conception. Although some young adults said they wished to meet their donor, this did not necessarily mean they were actively searching for them.

'I'm the only mum she knows': parents' understanding of, and feelings about, identity-release egg donation

STUDY QUESTION

How do parents understand and feel about identity-release egg donation?

SUMMARY ANSWER

Almost one-third of mothers and fathers did not understand the identifiable nature of their egg donation; mothers expressed complex and sometimes difficult feelings about the prospect of future donor–child contact.

WHAT IS KNOWN ALREADY

Identity-release egg donation has been the only treatment option available to patients wishing to pursue this route to parenthood in the UK since 2005. However, little is known about how well parents understand this legislation, and how they feel about potential donor–child contact.

STUDY DESIGN, SIZE, DURATION

This qualitative interview study included 61 mothers and 51 fathers whose 5-year-old children were conceived via identity-release egg donation. Interviews were conducted between April 2018 and December 2019.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Data are reported from phase two of a longitudinal study of families created using open-identity egg donation. In-depth, semi-structured interviews were conducted with mothers and fathers. The interviews contained a section on what parents understood about the identifiable nature of the donor. These data were analysed using qualitative content analysis. Mothers who understood the identifiable nature of their egg donation (n = 44) were then asked about their thoughts and feelings regarding the prospect of future donor–child contact. Mothers’ narratives were analysed using thematic analysis.

MAIN RESULTS AND THE ROLE OF CHANCE

Almost one-third of parents (28% of mothers, n = 17; 31% of fathers, n = 16) did not understand the identifiable nature of their egg donation. Mothers’ and fathers’ misunderstandings about identity-release egg donation fell into two categories: (i) Unclear about identity-release and (ii) Belief that the donor is anonymous. Reflexive thematic analysis revealed that egg donation mothers’ feelings about identity-release donation could be understood via three organizing themes: (i) identity-release as a threat, (ii) acceptance: it is what it is and (iii) embracing identity-release. The findings indicated that egg donation mothers utilized various strategies to manage their feelings about identity-release egg donation in day-to-day life, and each theme was associated with at least one coping strategy.

LIMITATIONS, REASONS FOR CAUTION

Participants were predominantly from White, middle-class backgrounds. Further research with a more diverse sample is needed to improve generalizability.

WIDER IMPLICATIONS OF THE FINDINGS

These findings indicate that parents would benefit from more comprehensive provision of information, both at time of treatment and following conception, to ensure they have fully understood the nature of the donation. Parents may also benefit from follow-up care to help manage any complex or difficult feelings about donor–child contact.

O-211 Families created through identity-release egg donation: parents’ understanding of, and feelings about, donor identification in early childhood

Study question

How well do parents understand identity-release donation, and how do they feel about potential donor-child contact?

Summary answer

Almost one-third of mothers (28%) and fathers (31%) did not understand the identifiable nature of their egg donation. Mothers expressed considerable ambivalence about donor-child contact.

What is known already

Egg donation is an increasingly common method of conception for women who are unable to use their own eggs. Identity-release egg donation has been the only treatment option available to patients wishing to pursue this route to parenthood in the UK since 2005. Despite this, little is known about how well parents understand this legislation, and how they feel about potential donor-child contact. At 18 years, donor-conceived offspring can request identifying information about their donor. The first UK cohort of identity-release offspring will turn 18 in 2023; understanding parents’ comprehension of, and feelings about, identity-release is therefore particularly timely.

Study design, size, duration

Data are reported from phase two of a longitudinal study of families created using open-identity egg donation, when children were aged five. At phase one, 85 families were recruited through 12 UK fertility clinics. An 85% response rate was subsequently achieved at phase two. A sub-sample of sixty-one mothers and 51 fathers were included in the present analyses. This qualitative investigation explored parents’ level of understanding of, and egg donation mothers’ feelings about, identity-release donation.

Participants/materials, setting, methods

In-depth, semi-structured interviews were conducted with mothers and fathers. The interviews contained a section on what parents understood about the identifiable nature of the donor. These data were analysed using qualitative content analysis. Mothers who understood the identifiable nature of their egg donation (n = 44) were then asked about their thoughts and feelings regarding the prospect of future donor-child contact. Mothers’ narratives were analysed using thematic analysis.

Main results and the role of chance

Almost one third of parents (27.9% of mothers, n = 17; 31.4% of fathers, n = 16) did not understand the identifiable nature of their egg donation. Qualitative content analysis revealed two main types of misunderstanding: i) parents whose understanding of identity-release was incorrect or incomplete (n = 26, 10 mothers, 13 fathers) and ii) parents who believed their donor was anonymous (n = 10, 7 mothers, 3 fathers). Thematic analysis revealed that egg donation mothers’ feelings about identity-release donation could be understood in relation to three main themes: 1) Identity-release as a threat, 2) Acceptance: it is what it is, and 3) Embracing identity-release. Mothers had complex and sometimes contradictory feelings about the prospect of future donor-child contact, and used a number of strategies to manage those feelings in day-to-day life. Donor-child contact was commonly perceived as a threat to the mother-child relationship, to the child, and to the donor. Conversely, the possibility of future donor-child contact was viewed by some mothers as an opportunity to be embraced; access to the donor’s identifying information was seen as essential to the child’s identity, and as a gateway to a broader family network.

Limitations, reasons for caution

Participants were predominantly from White, middle-class backgrounds. Further research with a more diverse sample is needed to improve generalisability. However, no other research has yet examined egg donation parents’ understanding of, and feelings about, identity-release donation in the UK. This research is therefore an important addition to the limited literature.

Wider implications of the findings

These findings indicate that parents would benefit from more comprehensive provision of information, both at time of treatment and following conception, to ensure they have fully understood the nature of the donation. Parents may also benefit from follow-up care to help manage any complex or difficult feelings about donor-child contact.

Parent-child relationship quality and child psychological adjustment in families created using egg donation: children's perspectives at age 5 years

STUDY QUESTION

What are children’s perspectives of the quality of their relationships with their parents and their own psychological well-being in families created using egg donation?

SUMMARY ANSWER

Children’s scores indicated good parent–child relationship quality and high levels of psychological well-being, with children in families created using egg donation rating their relationships with their mothers as higher in warmth/enjoyment than children in a comparison group of families created using IVF.

WHAT IS KNOWN ALREADY

Little is known about how children in families created through egg donation view their family relationships and their own psychological well-being. Research with 7-and-10-year-olds in anonymous egg donation families has indicated good parent–child relationship quality from children’s perspectives, but studies have not involved younger children or those conceived following identity-release egg donation.

STUDY DESIGN, SIZE, DURATION

This study included 50 children who had been born through egg donation and a comparison group of 43 children conceived through IVF with the parents’ own gametes. Data were collected between April 2018 and December 2019. The sample forms part of a larger longitudinal study examining family functioning in families created through fertility treatment.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Children were aged 5 years old and had been born into families with different-sex couple parents. All families were visited at home. Children were administered the Berkeley Puppet Interview, a standardized assessment of parent–child relationship quality and psychological well-being.

MAIN RESULTS AND THE ROLE OF CHANCE

Children in egg donation families rated their relationships with their mothers as higher in warmth and enjoyment than did children in IVF families. No differences were found between the two family types in children’s ratings of the father–child relationship, or in children’s ratings of their own psychological well-being.

LIMITATIONS, REASONS FOR CAUTION

It is possible that children who did not consent to take part in the research had less positive perceptions of their family and themselves than children who participated.

WIDER IMPLICATIONS OF THE FINDINGS

The findings are relevant to UK clinics offering identity-release egg donation, to parents who have used egg donation to create their family and to individuals and couples considering their fertility treatment options. That children in egg donation families were more similar than different to children in IVF families in their self-concept and perception of their family relationships should prove reassuring.

Psychological well-being of identity-release egg donation parents with infants

STUDY QUESTION

What are the psychological health, relationship quality and perceived social support outcomes of heterosexual couples who have conceived an infant through identity-release egg donation?

SUMMARY ANSWER

Parents' scores on all measures were within the normal range. Egg donation mothers had poorer perceived social support, and egg donation fathers had less optimal psychological health than a comparison group of IVF parents, although these differences were associated with the older age of egg donation parents, rather than being an effect of family type.

WHAT IS KNOWN ALREADY

There is limited understanding of the psychological health and couple relationship quality of egg donation parents, and no empirical data on parents' social support, during the first year of parenthood. No studies have included families who have used an identity-release egg donor. The study offers the first examination of the psychological well-being of identity-release egg donation parents.

STUDY DESIGN, SIZE, DURATION

This study included 57 families created through identity-release egg donation, and a comparison group of 56 families who had used IVF with their own gametes, recruited through UK fertility clinics. Families were visited at home between October 2013 and June 2015. The sample forms part of a larger study examining family functioning in families created following fertility treatment.

PARTICIPANTS/MATERIALS, SETTING, METHOD

All families were heterosexual two-parent families with an infant aged 6-18 months. Mothers and fathers were administered standardised questionnaires assessing psychological health (Edinburgh Postnatal Depression Scale, Trait Anxiety Inventory and Parenting Stress Index-short form), couple relationship quality (Golombok Rust Inventory of Marital State) and perceived social support (Multidimensional Scale of Perceived Social Support).

MAIN RESULTS AND THE ROLE OF CHANCE

Scores from the egg donation and IVF parents were within the normal range on all measures. Significant differences were found between the groups indicating less optimal social support in egg donation mothers compared to IVF mothers, and poorer psychological health in egg donation fathers compared to IVF fathers. These differences appeared to be related to the older age of egg donation parents or to twin parenthood, rather than to egg donation per se. No differences were found between the groups in the parents' relationship quality.

LIMITATIONS, REASONS FOR CAUTION

It is possible that families who were managing the transition to parenthood less well may have been less likely to participate in research. Fewer IVF than egg donation fathers participated in the study, so the statistical power was lower for comparisons between fathers.

WIDER IMPLICATIONS OF THE FINDINGS

The findings are of relevance to UK clinics offering identity-release egg donation. That scores of egg donation parents on measures of psychological well-being were more similar than different to those of IVF parents should prove reassuring to individuals considering this treatment type. As less optimal outcomes were found for egg donation parents on several measures, and these were associated with parental age rather than conception type, it is recommended that clinics discuss with older patients how they may establish a social support network and signpost patients to appropriate post-natal support.

Detection of Isolated Mammary Carcinoma Cells in Marrow of Patients with Primary Breast Cancer

Single cells from mammary carcinoma infiltrating bone marrow can be detected in marrow aspirates using immunocytochemical stains for epithelial membrane antigen (EMA). This technique has been used to examine marrow aspirates taken from multiple sites from 24 patients at surgery for breast cancer. Ten of these patients had EMA-positive cells in their marrow, while 32 marrow samples from patients who did not have carcinoma were negative. These results have been combined with those obtained by taking aspirates from single sites from 47 breast patients without known skeletal deposits. Follow up showed that the patients with EMA-positive cells in their marrow developed bone metastases at a significantly faster rate.

The clinical utility of genetic testing of tissues from pregnancy losses

OBJECTIVE

To map the current testing being undertaken following pregnancy loss across the UK and to examine the clinical utility in terms of identifying a cause for the loss and in identifying couples at risk of an unbalanced liveborn child.

DESIGN

Retrospective audit.

SETTING

UK, for the year 2014.

POPULATION

An audit of 6465 referrals for genetic testing of tissue samples following pregnancy loss.

METHODS

Data were obtained by questionnaire from 15 UK regional genetics laboratories.

MAIN OUTCOME MEASURES

Data were analysed with respect to gestational age, the presence of identified fetal anomalies, methodologies used, abnormality rates and the presence of a parental balanced rearrangement.

RESULTS

Of 6465 referrals a genetic cause was identified in 22% of cases (before 12 weeks' gestation, in 47%; at 12-24 weeks, in 14%; after 24 weeks, in 6%). In 0.4% of cases a balanced parental rearrangement was identified where there was a risk of an affected liveborn child in a future pregnancy. Eighty percent of genetic imbalances identified were aneuploidy or triploidy and could be identified by quantitative fluorescence polymerase chain reaction alone. There was significant variation across the UK in acceptance criteria, testing strategies and thus level of resolution of testing.

CONCLUSIONS

Genetic testing of tissues following pregnancy loss identifies a probable cause of fetal demise in 22% of cases, but it is of low clinical utility in identifying couples at risk of a future unbalanced liveborn child. A comprehensive multidisciplinary review is needed to develop proposals for an affordable and equitable service.

TWEETABLE ABSTRACT

UK audit of genetic testing of fetal loss shows variation in access to and resolution of analysis.

Sliding trochanteric osteotomy preserves favorable abductor biomechanics in revision total hip arthroplasty

The outcome of sliding trochanteric osteotomy in revision total hip arthroplasty was assessed by comparing preoperative and postoperative static radiographic biomechanics and clinical hip abductor function of 22 consecutive operations (20 patients). Preoperative and postoperative pelvic radiographs were reviewed to quantify the biomechanical reconstruction of the hip abductor mechanism. Abductor muscle length and abductor moment arm were increased significantly (P <.05) by the operation. There was a significant (P <.05) increase in maximum degrees of active hip abduction from the preoperative to the postoperative state, an average of 32 months (range, 6-65 months) after surgery. The dysfunction index (a radiographic representation of hip torque) correlated positively (r =.63; P <.05) with active hip abduction. Sliding trochanteric osteotomy improves abductor biomechanics and may protect against trochanteric migration in revision total hip arthroplasty.

Outcome of total hip arthroplasty in small-proportioned patients

In a prospective, consecutive series, 41 total hip arthroplasties were performed in 27 small-proportioned patients with small femoral dimensions. The 17 female and 10 male patients averaged 23.6 years (range, 14-47 years), and the mean height and weight were 157 cm (range, 132-183 cm) and 53.5 kg (range, 36-84 kg). The most common preoperative diagnosis was juvenile rheumatoid arthritis in 18 patients (28 hips). Most patients were severely disabled in their daily activity, and 68% of the patients were classified as Charnley functional class C. The femoral implants consisted primarily of the proximally porous-coated miniature Anatomic Medullary Locking femoral component (AML/CDH, Depuy, Warsaw, IN) in 33 hips in 22 patients (average stem diameter, 9.5 mm; range, 8-12.0 mm). A porous ingrowth acetabular cup fixed with screws was used in all procedures. At an average follow-up of 51 months, Harris Hip Scores improved significantly from 34 points (range, 0-65 points) preoperatively to 85 points (range, 33-100 points) after arthroplasty. There were no intraoperative complications. There was 1 revision because of femoral implant loosening. Three cementless femoral components showed evidence of nonprogressive subsidence. One patient had significant bilateral acetabular component polyethylene wear and underwent revision. All other femoral and acetabular components were radiographically stable. The relief of pain and improvement of function were dramatic. The miniature AML/CDH femoral component, combined with an uncemented acetabular cup, provides a promising, off-the-shelf alternative in small-proportioned patients.

A clinical and radiographic study of the "safe area" using the direct lateral approach for total hip arthroplasty

The purpose of this clinical and radiographic study is to determine whether the surgeon can remain within the 5 cm "safe zone" while using the direct lateral approach during total hip arthroplasty (THA) without endangering the superior gluteal nerve. The direct lateral approach was used in a prospective, consecutive series of 36 primary THAs in 31 patients performed by one surgeon. At the time of closure of the abductor muscle layer, a small metallic clip was placed at the superior extent of the incision into the gluteus medius. After surgery, the patients were mobilized on crutches with protected weight bearing for either a 6-week (hybrid THA) or 12-week (uncemented THA) period. Before surgery, and at 3, 6, and 12 months after surgery, abductor strength and the Trendelenburg sign were measured by the same physical therapist. The vertical distance from the superior pole of the greater trochanter to the base of the clip was measured on all radiographs of the pelvis and corrected for magnification. Before surgery, only 25 of the 36 hips demonstrated abduction strength of 4/5 or greater. Three months after surgery, 34 hips had a grade of 4/5 or greater for abductor strength. The Trendelenburg sign was positive in 24 of 34 hips before surgery, in 5 hips at 3 months, in 1 hip at 6 months, but negative in all hips by 12 months. The clip was located 3.2 +/- 1.3 cm (mean +/- SD) vertically from the superior pole of the greater trochanter. In 34 of 36 hips (95%), the 5 cm safe zone was respected.(ABSTRACT TRUNCATED AT 250 WORDS)

Midtrimester chorionic villus sampling: an alternative approach?

OBJECTIVE

Our purpose was to audit midtrimester chorionic villus sampling after a positive maternal serum screening test for autosomal trisomy.

STUDY DESIGN

From January 1990 until July 1993 chorionic villus sampling was offered to all screened positive women.

RESULTS

Five hundred fifty-one mothers had chorionic villus sampling. The mean age was 31.7 years. The mean gestational age was 18.2 weeks. The mean time for direct karyotyping was 4.4 days and for culture results 20.2 days. Results were obtained in 99.6% of samples: direct plus culture results in 94%, direct results alone in 2.3%, and culture results alone in 3.3%. Fourteen pregnancies had abnormal karyotypes. There were five cases of placental mosaicism and one false-positive result. The loss rate was 0.4%.

CONCLUSION

Midtrimester chorionic villus sampling, which is easier to perform than cordocentesis, provides a rapid and reliable karyotype. The complication rate is comparable to that of other invasive procedures.

Preoperative templating for the equalization of leg lengths in total hip arthroplasty

The method and results of preoperative templating for the re-establishment of leg length equality during total hip replacement (THR) are reported. The method is a modification of the technique of Müller and requires an anteroposterior radiograph of the pelvis that includes the proximal third of both femora, appropriate acetabular and femoral templates, and tracing paper. To obtain equalization of leg lengths and tissue tension, a composite drawing is made of the operative plan, with all component sizes and important measurements clearly marked. During THR, the lesser trochanter is identified and the femoral neck is osteotomized after a direct measurement is made. These principles were followed in a prospective, consecutive series of 42 primary THR procedures performed by one surgeon. All the radiographic measurements were performed by a single observer. The leg length discrepancy on the postoperative radiograph averaged 3mm (standard deviation = 3mm, range: -9 to +9mm). The postoperative clinical leg length discrepancy averaged 0mm (range: -10 to +10mm). None of the patients complained of leg length inequality. Preoperative templating allows different alternatives to be traced on paper prior to the actual surgical procedure. This method also helps determine the requirements for special prosthetic implants. Acceptable results for postoperative leg length equality may be reliably achieved using this method.

The site of binding of anti-CEA antibodies to tumour CEA in vivo: an immunocytochemical and autoradiographic approach

Radiolabelled affinity-purified antibody to carcinoembryonic antigen (CEA) was injected i.v. into immune-suppressed mice carrying xenografts of human breast carcinoma. Its distribution in the tumours was examined by a combination of immunocytochemistry and autoradiography. The antibody interacted predominantly with the CEA in the extracellular tumour space, rather than on the cell membrane or cytoplasm.
