BACKGROUND The high number of IVF procedures performed in Israel has had an unforeseen consequence: accumulation of large amounts of surplus frozen embryos. After five years that the frozen embryos are kept for free, patients need to make an embryo disposition decision. One option is donation for research. The donation rate in Israel is very low. Our aim was to understand the attitudes, values ...

The outcome of an embryo donation programme was evaluated and attitudes among donors and recipients studied by means of a questionnaire survey. A total of 27 couples went through 54 treatment cycles with frozen-thawed embryos donated by other infertile couples. The indications for treatment were premature or incipient ovarian failure in combination with severe male factor infertility. The mean ...

A polysyloxane vaginal ring containing 1g of natural progesterone was developed as luteal supplementation for women treated with IVF-embryo transfer and for agonadal women participating in an oocyte donation programme. The ring provides continuous release of progesterone (10-20 nmol/l) for 90 days. The efficacy of this form of progesterone supplementation was evaluated in two multicentre prospe...

OBJECTIVE One byproduct resulting from free radical damage is the DNA hydroxylation also known as DNA oxidation. Our aim with this work was to determine the relevance of sperm DNA oxidation on embryo quality in oocyte donation cycles. DESIGN We prospectively studied pairs of oocyte donation cycles, i.e., the same oocyte donors, donating to two recipients, where the only difference between the...

This article is a response to McLeod and Baylis (2007) who speculate on the dangers of requesting fresh 'spare' embryos from IVF patients for human embryonic stem cell (hESC) research, particularly when those embryos are good enough to be transferred back to the woman. They argue that these embryos should be frozen instead. We explore what is meant by 'spare' embryos. We then provide empirical ...

BACKGROUND We aimed to assess the validity of a theoretical mathematical model to predict the pregnancy rate and the multiple pregnancy rate in IVF/oocyte donation programmes on the basis of the implantation rate and the number of transferred embryos. METHODS A total of 1835 embryo transfers corresponding to three different programmes in two centres with different implantation rates were anal...

Building families through adoption of children has been supported by human society throughout history. The ethical appropriateness of patients donating embryos to other patients for family building, or for research, is well established and is affirmed by this body. The use of the term "adoption" to embryos is inaccurate and should be avoided. This document replaces the ASRM Ethics Committee sta...
