Embryo transfer

Twin studies aid in strengthening the correlations between fetal environment, low birth weight, and adult disease. On average, twins have lower than average birth weight as they experience reduction in growth during their third trimester due to limitations in size of the uterus (Vagero & Leon, 1994). Research involving monozygous and dizygous twins has determined that the lighter twin was more likely to develop higher blood pressure and have increased cardiovascular disease risk (Baird, Osmond,…

Pharmaceutical drugs are defined as drugs prescribed by a doctor or bought over-the-counter (OTC) for medicinal purposes. In relation to pregnancies, prescription and OTC drugs can affect pregnant women and their child in positive and negative ways. These pharmaceutical drugs have helped women maintain health conditions and aid in overcoming the discomforts a pregnancy brings, yet have the potential to cause harm to the fetus. Studies have been rather limited in both their research and results,…

that some of the eggs had not been properly sterilized, likely some bacteria or fungus was introduced into the egg yolk and caused the embryos to die and later decompose. For future experiments proper aseptic technique to avoid contamination must be followed. Further, the data collected for table 1 was made by approximating the developmental stage of the chick embryos instead of using the Hamburger and Hamilton table, this left us with data that was unreliable and we were unable to use because…

two lateral hemispheres. It is roughly spherical but somewhat constricted in its median region and flattened, the greatest diameter being transverse. The cerebellum develops from the dorsolateral part of the alar lamina of the metencephalon. In the embryo cerebellum appears at the end of the fifth week as a swelling overriding the fourth ventricle. Since cerebellum lies in the posterior cranial fossa, surrounded by the dense petrous ridges and the occipital bone so it can withstand deformation…

even though under normal circumstances there would be a 50 percent chance of the gene being passed on (Moyer). However, this is the basis of what is so scary about designer babies. If people figure out what genes tend to cause problems and check embryos for them, they will get rid of certain genes. That might not be a bad thing; however, those genes could have a benefit or function that people are unaware of. That is why it is so risky to get rid of or mess with specific…

protect the baby throughout the prenatal period. All though all three of the supporting structures are important, but the placenta is mainly the most important. The placenta provides the exchange of waste and nutrients between the mother and embryo. The mother and embryo don’t share the same blood, which is the make reason for placenta. Understanding Human Development states “the placenta permits the exchange of nutritive and waste materials by diffusion across cell membranes, normally without…

Effects of Drinking While Pregnant According to the journal, An Argument That Goes Back To The Womb, throughout the past 43 years, there has been battle after battle over the right or wrongness of drinking while pregnant. Since alcohol was legalized, women have the right to drink so long as they are of age, but when Fetal Alcohol Spectrum Disorders (FASD) were discovered it forced women to stop thinking of their rights and think about the baby in the wombs rights by making the right choice to…

involves taking a cell, extracting its DNA and using it to create a genetically identical individual in a dish and inserting this newly synthesized embryo into a female’s uterus. The implantation process of reproductive cloning is the same method used in in vitro fertilization. On the other hand, therapeutic cloning involves keeping the newly created embryo in a dish in the lab. Therapeutic cloning promises many medical advances and the possibility of finding cures for many as of yet incurable…

In Vitro Fertilization and Cas9 By Cody Dyess ENC1102 Professor Rivers 11/20/17 Outline I) Introduction A) Gene therapy B) Thesis statement: Cas9 should be used for gene therapy in in vitro fertilization to stop genetic disorders from developing in children. II) Defining what Cas9 is III) The history of Cas9 IV) Defining in vitro fertilization and its history A) Discovery B) Implementation V) Merging Cas9 with in vitro fertilization VI) Results of Cas9 against disease VII) Cas9’s…

In Frankenstein, Nature and science have brought a significant impact onto the characters. The progression of science combined with nature leads to a debacle. With this, there are various effects and roles shown through nature and science. Mary Shelley expresses her message about this. In her times, she was part of the transition from the Enlightenment to the Romanticist age and this led her to composing a story with nature and science competing against each other. From the struggles between the…
