Abstract Purpose The objective of this meta-analysis is to determine whether there is a higher incidence of preeclampsia (PE) in pregnancies achieved by oocyte donation (OD) compared with pregnancies achieved by in vitro fertilization with autologous oocytes (IVF). Methods A systematic review was performed to identify relevant studies published from January 1994 until April 2015 with at least a...

Currently in China, health regulations permit oocyte donation only from IVF/ICSI patients who have 20 or more mature oocytes retrieved from a single cycle, of which at least 15 must be kept for their own treatment. Oocyte donation from non-patients and commercial transaction of human gametes are strictly prohibited by law. Additionally, embryos derived from donated oocytes must be cryopreserved...

Including infertility treatments, sperm donations is a technique in combination with advances in medical knowledge with sperm, Oocyte and after the specified time and process, transfer the embryo into the uterus of female applicants. With the passage of the Act in 2003 and its implementation in 1383, there is no legal problem in this regard. However, many questions about this issue in terms of ...

BACKGROUND Race and ethnicity are one of the newly investigated patient-related prognostic factors that might affect the outcome of assisted reproduction techniques. To our knowledge no data currently are available on the effect of race on oocyte donation outcome. MATERIALS A retrospective, matched cohort study was performed in a private infertility centre evaluating 1012 Black, South-East As...

BACKGROUND The percentage of women giving birth after the age of 35 increased in many western countries. The number of women remaining childless also increased, mostly due to aging oocytes. The method of oocyte donation offers the possibility for infertile older women to become pregnant. Gestation after oocyte-donation-IVF, however, is not without risks for the mother, especially at advanced ag...

Treatment of same-sex couples using infertility therapies has become more acceptable over the years, but remains controversial. In December 2005, two law changes came into force in the UK that impact same-sex couples. Firstly, the Civil Partnership Act 2004 acknowledged legal relationships between same-sex couples; and secondly, the Adoption and Children Act 2002 allowed same-sex couples to ado...

BACKGROUND Fragile X syndrome is associated with low ovarian reserve and poor ovarian response. The aim of this study was to investigate whether CGG repeats on the fragile X mental retardation 1 (FMR1) gene have predictive value for ovarian response to stimulation with gonadotrophins and for clinical outcome in our oocyte donation program. METHODS Oocyte donor candidates were selected accordi...

There are numerous studies concerning pregnancy rates in oocyte donation, yet only a handful report the obstetric outcome in such pregnancies. The purpose of this study was to assess factors that influence pregnancy rates, to determine the incidence of complications, and to evaluate obstetric outcome in pregnancies resulting from oocyte donation. This study included 423 oocyte recipients who un...

OBJECTIVE To analyze the differences in placental perfusion in pregnancies following oocyte donation compared to spontaneous pregnancies. PARTICIPANTS AND METHODS A total of 33 patients who became pregnant after oocyte donation are studied and compared to 42 spontaneously pregnant participants. A 3-dimensional Power Doppler is used to obtain 3 placental volumes. Of each volume, 3 portions are...

Aim: To summarize recent articles on the risk factors of preeclampsia in twin pregnancies from 2002 to 2014. Methods: Recent articles from 2002 to 2014 were searched using PubMed. Results: We found 8 articles analyzing the risk factors of preeclampsia in twin pregnancies and focused on the following three risk factors: i) egg (oocyte) donation, ii) chorionicity (dichorionic (DC) twins vs. monoc...
