An evidence-based policy for the provision of subsidised fertility treatment in California: Integration of array comparative genomic hybridisation with IVF and mandatory single embryo transfer to lower multiple gestation and preterm birth rates
… molecular cytogenetic techniques has shown that single embryo transfer (SET) with IVF can now lift pregnancy rates to an acceptable level while not altering the normal multiple gestation rate. This approach would effectively solve the preterm and multiple gestation problem historically associated …

The Impact of Reproductive and Birth Technologies on Health, Fertility and Labor Outcomes
… fertilization (IVF) procedures, mandating single embryo transfer as default. In the last chapter, we study the effect from abortion legalization in Mexico City on fertility, contraceptive use and female empowerment.

Momentary exposure to a microfluidic environment seems to enhance embryo development
… need for an objective and non-invasive method of embryo selection to allow for single embryo transfer is needed to increase the success rates and while simultaneously decreasing the multiple birth rates. One such method being tested uses a device that measures the specific gravity (SG) of embryos …

Microfluidic tools for metabolomics
A primary challenge in embryology is to understand the factors that govern the development of preimplantation (PI) embryos and how these factors relate to embryo viability in the field of in vitro fertilization (IVF). This is particularly important as clinical policy moving towards single embryo …

Predicting successful outcome of singleton and multiple pregnancies after assisted reproductive technologies (ART)
… retrospective study of the pregnancy outcomes of singleton and twin pregnancies conceived from ART. The study found that ART conceived twins had similar perinatal outcomes to spontaneously conceived twins. Overall, singleton pregnancy outcomes were very favourable. Singleton pregnancies, when …

Embryo Adoption: Implications of Personhood, Marriage, and Parenthood
… will influence his moral belief regarding embryo adoption. In Chapter One, I consider the personhood of the human embryo. If the human embryo is a person, we are morally obligated to permit the practice of embryo adoption as an ethical means to save human persons. However, for those who do …

Νευραναπτυξιακές διαταραχές στην υποβοηθούμενη αναπαραγωγή
… Η εκλεκτική μεταφορά ενός εμβρύου (elective single embryo transfer, eSET) έχει προταθεί ως στρατηγική που μπορεί να μειώσει τους κινδύνους αυτούς, συμβάλλοντας στη βελτίωση των περιγεννητικών εκβάσεων. Συμπερασματικά, η υποβοηθούμενη αναπαραγωγή αποτελεί μία πολύτιμη ιατρική πρακτική που έχει …

A mosquito-specific bZIP transcription factor and the influence of a Y-specific gene on sex determination in Anopheles stephensi
… few model organisms, little is known about early embryonic development or sex determination in insects, in particular mosquitoes which are major vectors of worldwide disease. The goals of this work were to investigate a mosquito-specific transcription factor and its intronic miRNA cluster and …

Embryo Production by Superovulation and Dual Siring in Alpacas
… the genetic gain of a herd, superovulation and embryo transfer techniques can be used to produce multiple embryos from genetically superior females. We hypothesized that the use of superovulation and dual siring results in the production of multiple embryos sired by both of the males. Our …

How the Heart Grows: From Multi-scale Data to a Multi-scale Model
… the first to function during early development. Embryological heart development consists of a series of events believed to be highly conserved in vertebrates. Cardiac precursor cells form a cardiac crescent at the embryonic midline. Fusion of the cardiac crescent results in the linear heart tube …

Studies on the factors that improve the outcome of IVF-ET
… and a retrospective analysis of the result of a single IVF unit over a 6 year period from 1999 to 2005. This identified a number of factors on which IVF pregnancy rates depend.I found that there is a decrease in the pregnancy and implantation rates and an increase in the abortion rates with a …

Impacto de un modelo educativo sobre la transferencia embrionaria en pacientes de Reprotec – Hospital Universitario Fundación Santa Fe de Bogotá en 2016 – 2017
Introducción: El ideal de la reproducción asistida es un recién nacido y una madre vivos y sanos en casa. Sin embargo, la intención de proveer la experiencia gestacional a nuestra sociedad, ha generado un aumento significativo en el número de embarazos múltiples, gestaciones que tendrán un mayor …
