In most in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) programmes approximately one ongoing pregnancy in three is multiple. The need to characterize embryos with optimal implantation potential is obvious. We retrospectively examined all of 23 double transfers resulting in ongoing twins, occurring between January 1, 1996 and May 19, 1997. Characteristics of these top qualit...
Non-invasive prenatal testing (NIPT) by random massively parallel sequencing of maternal plasma DNA for multiple pregnancies is a promising new option for prenatal care since conventional non-invasive screening for fetal trisomies 21, 18 and 13 has limitations and invasive diagnostic methods bear a higher risk for procedure related fetal losses in the case of multiple gestations compared to sin...
OBJECTIVES To examine the rate of cerebral palsy in twins and triplets in births from 1980 to 1989 in Western Australia and to identify factors associated with increase in risk. DESIGN Pluralities for all births in Western Australia were identified through the standardised midwives' notification system, and cases of cerebral palsy were identified from the Western Australian cerebral palsy reg...
While the risk of ovarian cancer clearly reduces with each full-term pregnancy, the effect of incomplete pregnancies is unclear. We investigated whether incomplete pregnancies (miscarriages and induced abortions) are associated with risk of epithelial ovarian cancer. This observational study was carried out in female participants of the European Prospective Investigation into Cancer and Nutriti...
UNLABELLED The aim of this study was to determine the relationship between meningitis and neonatal period of complications such as massive intraventricular hemorrhage and into brain tissue, hypoxic-ischemic white matter injury retinopathy of prematurity 3-5 degrees and deafness in infants born prematurely from single and multiple pregnancies. MATERIAL The retrospective study covered 460 prete...
Background and purpose: Preeclampsia as the most common complication of pregnancies has unknown physiopathology. Because the role of serum Beta-human Chorionic Gonadotropin (B-hCG) in pathophysiology of preeclampsia is not well known, we decided to determine the correlation between serum concentration of B-HCG and preeclampsia . Materials and Methods: This case-control study performed on t...
BACKGROUND The risk of congenital anomalies in twins is higher than in singletons, but it is less well reported in relation to chorionicity. The aim of this study was to describe the prevalence of congenital anomalies in twin pregnancies by chorionicity and by major subtype and compare the rates with those in singletons. METHODS The study population included 2329 twin pregnancies (4658 twins)...
Our objective was to examine the relationship between patient weight and the dose of clomiphene required for pregnancy so as to assess the validity of recommendations that the dose of clomiphene be limited to 100 mg. We retrospectively analysed the weight-dose relationship in 1681 clomiphene pregnancies and the relationship between dose and pregnancy, births, multiple births, number of pre-ovul...
Case To present an extremely rare case of bilateral tubal pregnancies following a single-embryo transfer in a woman with a 4 year history of infertility prior to seeking assisted reproductive technology. Outcome A pregnancy resulted from the transfer of an embryo that had been thawed from a frozen blastocyst during a hormone replacement cycle. An ultrasound that was performed at 5 weeks and 5...
In-vitro fertilization is associated with a high rate of multiple pregnancies, a consequence of the number of embryos transferred. There is a challenge in avoiding even twin pregnancies in assisted reproduction, and this can be accomplished with elective single embryo transfer and a good cryopreservation programme. In our follow-up study, we analysed all our elective single embryo transfers dur...
