I-32: Management of Diminished Ovarian Reserve
The standard goal of all fertility treatments is the improvement of pregnancy rates in infertile patients. Within the last 20 years, ovulation induction has contributed to the success of assisted reproduction techniques e.g. in vitro fertilization (IVF) and embryo-transfer (ET). The efficacy of these techniques depends on a personalized protocol of controlled ovarian hyperstimulation (COH) and ...
متن کاملI-32: Avoiding OHSS in Ovarian Stimulation
Multiple pregnancies and ovarian hyper stimulation syndrome (OHSS) are the most serious complications of ovarian stimulation and IVF. Indeed, they are more or less the only ones. OHSS can effectively be prevented in three stages: Before stimulation, during stimulation and at ET. Before stimulation patients should be assessed as to age, the ovarian follicular count and/or anti mullerian hormone ...
متن کاملI-32: Implantation and Recurrent PregnancyLoss
Background: Recurrent pregnancy loss (RPL), defined as 3 or more consecutive pregnancy failures, is a common and distressing disorder. Chromosome instability in the conceptus is the most common cause whereas uterine factors are invariably invoked to explain nonchromosomal miscarriages. These uterine factors are, however, poorly defined. Materials amd Methods: Laboratory-based analysis of endome...
متن کاملAxiomatizing changing conceptions of the geometric continuuum I: Euclid-Hilbert
We begin with a general account of the goals of axiomatization, introducing several variants (e.g. modest) on Detlefsen’s notion of ‘complete descriptive axiomatization’. We examine the distinctions between the Greek and modern view of number, magnitude and proportion and consider how this impacts the interpretation of Hilbert’s axiomatization of geometry. We argue, as indeed did Hilbert, that ...
متن کاملComputational Euclid
We analyse the axioms of Euclidean geometry according to standard object-oriented software development methodology. We find a perfect match: the main undefined concepts of the axioms translate to object classes. The result is a suite of C++ classes that efficiently supports the construction of complex geometric configurations. Although all computations are performed in floating-point arithmetic...
