Synnytysiän ja hedelmällisyyden pulmallinen ristiriita

Monella on ylioptimistinen kuva hedelmöityshoitojen tehokkuudesta

Hedelmöityshoitojen mahdollisuudet

Vertaisarvioitu. Teema : hedelmällisyys. English abstract.Hedelmöityshoidot suunnitellaan hedelmättömyyden syyn ja keston sekä naisen iän mukaan. ¬Niistä saa avun 80 % pareista, kun naisen ikä on korkeintaan 35 vuotta. Koeputkihedelmöityksessä joka neljäs yhden alkion siirto johtaa lapsen syntymään. Lasten perinataali¬tuloksissa on pieniä eroja spontaanisti hedelmöityneiden lasten tilanteeseen. Suomessa hedelmöityshoitoja saa sekä omilla että luovutetuilla sukusoluilla julkisilla ja yksityisillä klinikoilla.Peer reviewe

Turnerin oireyhtymä aikuisiässä : hoito ja seuranta

Vertaisarvioitu. English summary.Turnerin oireyhtymä on monimuotoinen sairaus, johon liittyy ennenaikaisen munasarjojen vajaatoiminnan ja lyhytkasvuisuuden lisäksi useiden eri elimien sairauksien kehittymisen riski. Synnynnäiset sydämen ja munuaisten rakennepoikkeavuudet ovat yleisiä ja vaativat elinikäistä seurantaa. Lisäksi potilaiden verenpainetaudin, hyperkolesterolemian, tyypin 2 diabeteksen, keliakian, kilpirauhasen vajaatoiminnan, maksan toimintahäiriöiden ja sensorineuraalisen kuulovian riski on suurentunut. Myös neuropsykiatriset ongelmat ovat yleisiä. Hedelmättömyys on Turner-naisille suuri surun aihe, ja hedelmöityshoito luovutetuilla munasoluilla on osalle varteenotettava vaihtoehto saada oma lapsi. Monimuotoisen taudinkuvan vuoksi kokonaisvaltainen terveyden seuranta on tärkeää. Siirtyminen lasten erikoissairaanhoidosta aikuispuolelle on seurannan jatkuvuuden kannalta kriittinen vaihe. Gynekologit ovat avainasemassa seurannan koordinoinnissa.Peer reviewe

Obstetric and perinatal risks after the use of donor sperm : A systematic review and meta-analysis

Donor sperm is widely used in infertility treatments. The purpose of the study was to investigate, whether use of donor sperm in intrauterine insemination (IUI) or in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatments affect maternal and perinatal risks compared with spontaneously conceived pregnancies or use of partner sperm in IUI, IVF or ICSI. We provide a systematic review and meta-analyses on the most clinically relevant obstetric and perinatal outcomes after use of donor sperm compared with partner sperm: hypertensive disorders of pregnancy, preeclampsia, low birth weight, and preterm birth. Our meta-analyses showed an increased risk for preeclampsia (pooled adjusted odds ratio (aOR) 1.77, 95% CI 1.26-2.48) and hypertensive disorders of pregnancy (pooled aOR 1.55, 95%, CI 1.20-2.00) in pregnancies resulting from IUI with donor sperm compared with IUI with partner sperm. No increased risk was seen for low birth weight or preterm birth after the use of donor sperm in IUI compared with the use of partner sperm in IUI. Subgroup analysis for singletons only did not change these results. The meta-analysis on low birth weight showed a lower risk after in IVF with donor sperm compared with IVF with partner sperm (pooled aOR 0.89, 95% CI 0.83-0.94). For hypertensive disorders of pregnancy, preeclampsia and preterm birth, no difference was found between IVF with donor sperm vs. partner sperm. Patients need to be informed about the moderately increased risk of hypertensive disorders of pregnancy and preeclampsia in pregnancies after IUI with donor sperm.Peer reviewe

The Association Between High Birth Weight and Long-Term Outcomes—Implications for Assisted Reproductive Technologies: A Systematic Review and Meta-Analysis

Background: Studies have shown that the prevalence of children born with high birth weight or large for gestational age (LGA) is increasing. This is true for spontaneous pregnancies; however, children born after frozen embryo transfer (FET) as part of assisted reproductive technology (ART) also have an elevated risk. In recent years, the practice of FET has increased rapidly and while the perinatal and obstetric risks are well-studied, less is known about the long-term health consequences.Objective: The aim of this systematic review was to describe the association between high birth weight and LGA on long-term child outcomes.Data Sources: PubMed, Scopus, and Web of Science were searched up to January 2021. Exposure included high birth weight and LGA. Long-term outcome variables included malignancies, psychiatric disorders, cardiovascular disease, and diabetes.Study Selection: Original studies published in English or Scandinavian languages were included. Studies with a control group were included while studies published as abstracts and case reports were excluded.Data Extraction: The methodological quality, in terms of risk of bias, was assessed by pairs of reviewers. Robins-I (www.methods.cochrane.org) was used for risk of bias assessment in original articles. For systematic reviews, AMSTAR (www.amstar.ca) was used. For certainty of evidence, we used the GRADE system. The systematic review followed PRISMA guidelines. When possible, meta-analyses were performed.Results: The search included 11,767 articles out of which 173 met the inclusion criteria and were included in the qualitative analysis, while 63 were included in quantitative synthesis (meta-analyses). High birth weight and/or LGA was associated with low to moderately elevated risks for certain malignancies in childhood, breast cancer, several psychiatric disorders, hypertension in childhood, and type 1 and 2 diabetes.Conclusions: Although the increased risks for adverse outcome in offspring associated with high birth weight and LGA represent serious health effects in childhood and in adulthood, the size of these effects seems moderate. The identified risk association should, however, be taken into account in decisions concerning fresh and frozen ART cycles and is of general importance in view of the increasing prevalence in high birthweight babies

In vitro fertilization does not increase the incidence of de novo copy number alterations in fetal and placental lineages

Although chromosomal instability (CIN) is a common phenomenon in cleavage-stage embryogenesis following in vitro fertilization (IVF)1,2,3, its rate in naturally conceived human embryos is unknown. CIN leads to mosaic embryos that contain a combination of genetically normal and abnormal cells, and is significantly higher in in vitro-produced preimplantation embryos as compared to in vivo-conceived preimplantation embryos4. Even though embryos with CIN-derived complex aneuploidies may arrest between the cleavage and blastocyst stages of embryogenesis5,6, a high number of embryos containing abnormal cells can pass this strong selection barrier7,8. However, neither the prevalence nor extent of CIN during prenatal development and at birth, following IVF treatment, is well understood. Here we profiled the genomic landscape of fetal and placental tissues postpartum from both IVF and naturally conceived children, to investigate the prevalence and persistence of large genetic aberrations that probably arose from IVF-related CIN. We demonstrate that CIN is not preserved at later stages of prenatal development, and that de novo numerical aberrations or large structural DNA imbalances occur at similar rates in IVF and naturally conceived live-born neonates. Our findings affirm that human IVF treatment has no detrimental effect on the chromosomal constitution of fetal and placental lineages

Secrets and disclosure in donor conception

This paper considers the disclosure, sharing and exchange of information on being donor conceived within families, drawing on data from a study undertaken with donor-conceived adults registered with UK Donor Link (a voluntary DNA-linking register). It considers the narratives of how respondents found out they were donor-conceived and what events triggered disclosure of this information. It goes on to examine the role secrecy played in their family life and uses the concept of ‘display’ to explore how it affected their relationships with their immediate and extended family. Secrets are notoriously ‘leaky’ and we found complex patterns of knowing and uncertainty about whom in the family knew that the person was donor-conceived. We argue that what is kept secret and from whom provides insights into the multifaceted web of social relationships that can be created by donor-conception, and how knowledge can be managed and controlled in attempts to display and maintain family narratives of biogenetic connection

Anonimato e segredo na reprodução humana com participação de doador: mudanças em perspectivas

Resumo As tecnologias reprodutivas, ao separar a sexuali dade da reprodução, interferiram não somente nas relações entre os sexos, mas também nas relações de filiação, possibilitando o surgimento de configu rações familiares decorrentes do acesso a material genético de terceiros (doadores de óvulos, sêmen ou embrião). O segredo e o anonimato que sempre envolveram os doadores de gametas têm sido desa fiados. Nos últimos vinte anos, diversos países alte raram sua legislação adotando a identidade aberta do doador de material genético. A possibilidade de conhecer e ter acesso a esta identidade (chegando à maioridade) ou mesmo a busca por meios irmãos pode ser uma realidade em muitos países para crianças nascidas por meio do acesso à tecnologia reprodutiva. O artigo enfatiza a questão do segredo e do anonimato envolvendo o uso de material ge nético de terceiros em tecnologias reprodutivas. A discussão é explorada por meio do debate ocorrido no Reino Unido relativo à abolição do anonimato e suas implicações sob a perspectiva dos doadores, dos casais demandantes e da criança concebida. O estudo reflete ainda sobre as concepções de família envolvidas nessa discussão

Psychological and ethical issues in third party assisted conception and surrogate motherhood

The continuing increase in babies born via third party assisted conception (AC) and surrogate motherhood across the world shows the success of and medical and social demand for third party interventions in family building. However, with the increasing use of such interventions world-wide, commercialisation and commodification have proliferated. This in turn has led to inequality in access to AC services, in choice of third party input, and in questionable human rights and psychosocial welfare issues. Transitioning to parenthood using third party AC and surrogate motherhood, in addition to requiring equality in access, also demand accuracy of birth and genetic information. In the absence of accurate record keeping, continuing practices of anonymity, and marginalization of the contribution of donors and surrogates, psychological, social, health and ethical questions are raised for donors, recipients and potentially for (genetic, gestational) part, half and full offspring, siblings and others in the extended family such as grandparents
