STUDY QUESTION What are the experiences of donor-conceived adults and donors who are searching for a genetic link through the use of a DNA-based voluntary register service? SUMMARY ANSWER Donor-conceived adults and donors held positive beliefs about their search and although some concerns in relation to finding a genetically linked relative were reported, these were not a barrier to searching...

This study reports on the questions, thoughts and feelings of children aged 4-9 conceived by donor insemination to single mothers. Fifty-one mothers and 47 children from the same families were each administered a semi-structured interview. Mothers generally reported that while children either lack understanding, or have not yet been told, about their donor conception, they may be thinking and t...

It is shown that coordination chemical and extrathermodynamic models may be successfully applied to the qualitative and also quantitative description of fundamental chemical equilibria and reaction rates in non-aqueous solvents. Applications include: formation of charge transfer complexes, electrochemical reduction of metal cations, ionization of covalent compounds, ion association phenomena, o...

This Task Force document explores the ethical issues involved in the debate about the scope of genetic screening of gamete donors. Calls for expanded donor screening arise against the background of both occasional findings of serious but rare genetic conditions in donors or donor offspring that were not detected through present screening procedures and the advent of new genomic technologies pro...

BACKGROUND Previous data suggest that parents who adopt a child tend to support full disclosure while donor conception families prefer to keep the method of conception relatively private. It is not known whether parents in embryo donation families will tend towards the adoption model, therefore, we studied families with a child conceived using donated embryos. METHODS A total of 21 embryo don...

BACKGROUND Findings are presented of the second phase of a European longitudinal study of families created by assisted reproduction. The present investigation reports on data obtained during the child's transition to adolescence. METHODS A total of 102 IVF families, 94 donor insemination (DI) families, 102 adoptive families, and 102 families with a naturally conceived child were compared on s...

Rarely have donor conceived offspring been studied. Recently, it has become more common for parents to disclose the nature of conception to their offspring. This new development raises questions about the donor's place in the offspring's life and identity. Using surveys collected by the Donor Sibling Registry, the largest U.S. web-based registry, during a 15 week period from October 2009 to Jan...

Laparoscopic donor nephrectomy is a routine practice but still requires an intense level of attention to prevent complications. We report a rare case of gross hematuria in postoperative period after an uneventful laparoscopic donor nephrectomy.

The carrier profile for InAs films grown on GaP is modeled as a first-order approximation which assumes that 90° edge dislocation intersections and the threading dislocation intersections act as shallow donors. Due to dislocation annihilation during growth, the threading dislocation intersection density decreases as the inverse of the distance x from the InAs/GaP interface, D(x)5D0x0 /(x0 1x), ...
