Gender selection of the embryo prior to conception is one of the controversial topics‚ which has been widely debated considering different aspects. (1‚6) It is a dynamic topic to discuss‚ which raises arguments supporting and rejecting whether it is correct to perform the practice or not.

topic‚ and it can often provoke heated discussions amid the general public and those in academia. The core of the debate specifically revolves around embryonic stem cell research and the ethical implications that come with experimentation on human embryos. When discussing stem cell research it is important to obtain some background information to know where the debate originated. “There are three main sources for obtaining stem cells - adult cells‚ cord cells‚ and embryonic cells” (Stem Cell Research

unhealthy embryos. Embryos that show normal development are biopsied with micromanipulation techniques involving the use of very fine glass needles and tools under microscopic observation and control to obtain sufficient cells (blastomeres) for analysis. Based on animal experiments as well as 10 years of experience with PGD in humans‚ including over 200 normal births‚ it is felt that removal of small numbers of cells is unlikely to affect the continued development of a healthy embryo and foetus

As well as become a cure for neurological diseases like Alzheimer’s disease and Parkinson’s disease. Human embryonic stem cell research has enormous potential to cure many diseases and change the face of modern medicine. However‚ there is much debate against the use of embryos because many people believe that an embryo should be treated as a human

their certain job. They are developed in an incubator and gone under certain things to make them fit into a group. For instance‚ for a group that is not supposed to be very smart and is supposed to do manual work they will expose the embryo to chemicals throughout the embryos development to harm the development. Once they are born they are not released into the world until they are adults. The children are brainwashed growing up so that they do not threaten the World State. The World State is that everything

only God can judge. Even non religious people will accept the arguments I show. I think all rational people would agree with me that killing innocent human beings is immoral. My argument here will primarily be concerned with showing that unborn embryos are in fact human beings. A sperm is life. An egg is life. "Life" in this term does not demand our concern. We aren’t concerned with scratching our arm because we don’t want to kill skin cells. Humans‚ however‚ are quite important‚ and are deserving

Pregnancy is the fertilization and development of one or more offspring‚ known as an embryo or fetus‚ in a woman’s uterus. It is the common name for gestation in humans. A multiple pregnancy involves more than one embryo or fetus in a single pregnancy‚ such as with twins. Childbirth usually occurs about 38 weeks after conception; in women who have a menstrual cycle length of four weeks‚ this is approximately 40 weeks from the start of the last normal menstrual period (LNMP). Human pregnancy is the

Designer baby technology or reproductive genetics combines genetic screening and engineering1 processes with in vitro fertilization2 (IVF). This process is known as Pre-implantation genetic diagnosis (PGD). Steps: 1. Creating an Embryo with In-vitro fertilization (IVF). 2. Removing a single cell from that embryo within the first 5 days of creation 3. Genetically testing the
