The empirical study byMargaretNelson, RosannaHertz, andWendyKramer on stakeholder attitudes toward gamete donor anonymity and limits on gamete donation, ‘Gamete Donor Anonymity and Limits on Numbers of Offspring: The Views of Three Stakeholders’ (hereafter Gamete Donor Anonymity),1 is commendably particular on one level yet noticeably vague on another. It approaches the anonymity issue2 at a le...

The mixing of mitochondrial DNA (mtDNA) from the donor cell and the recipient oocyte in embryos and offspring derived from somatic cell nuclear transfer (SCNT) compromises genetic integrity and affects embryo development. We set out to generate SCNT embryos that inherited their mtDNA from the recipient oocyte only, as is the case following natural conception. While SCNT blastocysts produced fro...

This article explores the practice of gamete donation in the U.S. having in mind the larger question of what do we as a society owe children born as a result (donor-conceived children). Do recipient-parents have a duty to tell their donor-conceived child about his/her genetic origins? Should the identity of the donor be disclosed or remain anonymous? Does the child have a right to know her conc...

BACKGROUND This paper documents how couples and providers access donor materials for conception in the Indian context and perceptions about using them. The objective is to facilitate understanding of critical issues and relevant concerns. METHODS A postal survey was conducted with a sample of 6000 gynaecologists and in-depth interviews were -conducted with 39 gynaecologists in four cities. ...

the present study seeks to investigate users’ perception and evaluation of the function of designed environments and highlights a deeper understanding of man-environment relationship. the study tries to answer the question: “is there any relationship between the physical features of environment and users’ perception and evaluation of the environment and their spatial behaviors?” such investigat...

A case is described of a man who discovered years after donating sperm for artificial insemination, that he had a serious genetic disease, autosomal dominant cerebellar ataxia (ADCA). This manifests itself only years after puberty and occurs in 50% of the progeny. The sperm had been used for the conception of 18 children in 13 women. The parents were only told three years after the insemination...

Artificial insemination using cryogenically preserved spermatozoa has been widely used in human reproduction for several decades. No evaluation of the resulting pregnancies and conceptions has been undertaken in sufficiently large study populations for minor variations to be distinguished. This study involves 11,535 pregnancies conceived by artificial insemination using donor spermatozoa and fo...

Parents who use donor gametes should feel firm and entitled to say they are this child's parents. Health care providers (doctors, nurses, and social workers) must help these parents. Their decision to bring a child into the world creates continuous consequences for the whole family. The parents' responsibility is to attach, parent, and educate, and the child's responsibility is to ask questions...
