Adequate endometrial preparation with exogenous steroids is mandatory for successful ovum donation. This study was undertaken to assess the value of endometrial thickness by ultrasound and serum oestradiol as predictors of ovum donation outcome and to analyse the correlation between serum oestradiol concentrations and the endometrial thickness. Endometrial thickness and serum oestradiol concent...

BACKGROUND We aimed to investigate whether multifetal pregnancies are at risk of more pregnancy complications in women of advanced age after ovum donation. METHODS Pregnancy outcome in women after ovum donation aged 40 and above was extracted. Labor and delivery data as well as antenatal records of women carrying twins were compared with those of singletons, as well as to a control group of a...

This is a questionnaire based study of 501 women enquiring about anonymous oocyte donation at a private in-vitro fertilization (IVF) unit, investigating the demographic characteristics and logistic issues involved in ovum donation. The 501 women were made up of 356 women who did not donate ('non-donors') and 145 women who eventually donated their oocytes ('donors'). Although there was a majorit...

Assisted reproductive technology (ART), such as donor-assisted insemination (DI) relying on anonymous sperm donors, has been available since the 1940s, and it is assumed that tens of thousands of children throughout the world have been born through these procedures. Although anonymous DI has been occurring in Japan since the late 1940s, the use of egg donation has been a more recent development...

We have developed a coculture system with autologous human endometrial epithelial cells (AEEC) that retained many features of human endometrial epithelium. Implantation failure (IF; >3 previous cycles failed with 3-4 good quality embryos transferred) is a distressing condition in which 2-day embryo transfer repetition is the routine option. The objective of this study was to investigate the bas...

Evidence accumulated in in-vitro fertilization (IVF) cycles suggests that the use of long-acting forms of gonadotrophin-releasing hormone analogues (GnRHa) for pituitary desensitization may impair the outcome of IVF as compared to classical short-acting formulations. Whether the negative effects are directed against the corpus luteum, the endometrium, or both is unknown. However, the presence o...

We report the results of a qualitative study carried out in metropolitan Australia between 2009 and 2011 that canvassed the issue of payment for research oöcyte donation with participants drawn from three potential donor groups; fertility patients, reproductive donors and young, non-patient women. Research oöcytes are controversial tissues because women around the world have proved largely unwi...
