BACKGROUND To investigate the obstetrical and perinatal impact of oocyte donation, a cohort of women who conceived after OD was compared with a matched control group of women who became pregnant through in vitro fertilisation with autologous oocytes (AO). METHODS A matched-pair analysis has been performed at the Centre for Reproductive Medicine of the UZ Brussel, Dutch speaking Free Universit...

Relatively few countries have legislation addressing oocyte donation. Where such legislation does exist it is entirely in the context of broader legislation concerned with the regulation of in-vitro fertilization (IVF) or assisted reproduction more generally. Within Western Europe only nine countries so far have passed Acts addressing assisted reproduction. These countries fall into two groups ...

BACKGROUND Oocyte donation has been permitted by Swedish legislation since January 2003. While donors are anonymous to the receiving couple, offspring have the legal right to receive identifying information about the donor when they reach adult age. Our aim was to investigate factors of potential importance for women's willingness to donate oocytes. METHOD A questionnaire regarding attitudes ...

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...

STUDY QUESTION Do the socio-demographic and fertility-related characteristics and motivations of oocyte donors differ in European countries? SUMMARY ANSWER The socio-demographic and fertility-related characteristics and motivations of oocyte donors differ considerably across countries. WHAT IS KNOWN ALREADY There have been no other international studies comparing the characteristics of oocy...

BACKGROUND: Findings are presented of the third phase of a longitudinal study of children conceived by assisted reproduction procedures involving surrogacy and/or donor conception. METHODS: At the time of the child’s third birthday, 34 surrogacy families, 41 donor insemination families and 41 oocyte donation families were compared with 67 natural conception families on standardized interview an...

To expand the availability of stem cell lines suitable for basic research and clinical application, somatic cell nuclear transfer has been proposed and will require human oocyte donation. The recommendations made by the California Institute of Regenerative Medicine advisory committee on oocyte donation are based on peer-reviewed, best practices, and best clinical judgment and are intended to as...

The use of donor oocytes has expanded the scope of assisted reproductive technology (ART) for women with poor oocyte quantity and quality. In vitro fertilisation with oocyte donation (IVF-OD) is considered to give better implantation, pregnancy, and livebirth rates compared to IVF with autologous oocytes. Maternal age, infertility factors, BMI, smoker status, and ethnicity reduce reproductive o...

BACKGROUND Improvements in oocyte cryopreservation techniques and establishment of cryopreserved donor oocyte banks have led to improved access to and lower cost of donor oocytes, upending the traditional practice of fresh oocyte donation. The objective of this study was to examine national trends in utilization and live birth rates with fresh versus cryopreserved donor oocytes. METHODS A ret...

BACKGROUND Oocyte donation is a popular treatment option among women with ovarian dysfunction. Little is known about the amount of information recipients have about their donors and if the amount of information the couple has relates to their plans to disclose. The purpose of this study was to assess the amount of information recipients had about their donors and their disclosure plans. METHO...
