Fertilisation

*************************************************** Q: 1. Look at the male and female dragons on the left. Notice that they both have horns. Can two dragons with horns have a baby dragon with no horns? A: Yes Q: 2. Why do you think it can be done? A: If each parent has Hh to make up their horns, as long as the gametes that are used in fertilization are h, then the baby will have horns. Q: 3. OK, let's make sure you remember the rule for horns. Here's a little quiz: Which of these genotypes do…

The great hindrance to families across the world — infertility. Infertility is defined as the inability to conceive a child after one year of attempting to reproduce (Farlax). There are two branches of infertility: primary and secondary. Primary infertility occurs when a couple has yet to experience pregnancy. Secondary infertility occurs when a couple conceived a child, but were unable to conceive another child after one year of attempting to reproduce. Infertility has many causes: “ovulation…

I would suggest to Audrey and Andrew to go about having the children using in vitro fertilization and pre-implementation diagnosis. In order to maximize the benefits and minimize the harm, by doing so, even though there is a possibility of having mosaicism, they know for sure that their child would not have Duchenne Muscular Dystrophy, which will affect their child greatly if they have the disease. With 24% pregnancy rate, they can have a child without the disease. Therefore, the benefits in…

The author M. A. Garcia, did a wonderful thing in my opinion. She decided to take time to help out a lovely couple from Phoenix, Arizona; who were interested in buying her eggs. The couple wasn’t able to have kids, that’s why she decided to sell her eggs. Women should donate their eggs to infertile couple, if they choose not to have any children. If I was to donate my eggs to an infertile couple, I would make sure that I’m donating them to the right people. People may not be able to have kids…

The first form of pre-implantation procedures, taking place in Britain in 1990, was restricted from using the science in any way that could be perceived as unethical. These procedures were developed to help parents bear children free of harmful inherited conditions, known as "pre-implantation genetic diagnosis (PGD).” The PGD process begins with a test-tube evaluation of an embryo, removing any embryos containing a harmful disease. The embryos determined to be clear of any detrimental conditions…

Throughout history, mankind has made numerous strides in medicine, mainly in the contraceptive field. In today’s society there are many ways for women who are not able to naturally conceive a child; however, through artificial conception these women can now have a child of their own . In Vitro Fertilization was created in the 1970’s by Patrick Steptoe and Robert Edwards, to help women who have fertility issues due to a blocked or damaged fallopian tube (Zhu). Since the discovery of In Vitro…

Evidence from previous studies and analyses has shown there is a link between assisted conception and birth defects (1-6). There are two main types of assisted conception that are linked with birth defects: in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) (1-6). “In vitro fertilization (IVF) is the joining of a woman 's egg and a man 's sperm in a laboratory dish. In vitro means outside the body. Fertilization means the sperm has attached to and entered the egg (7).”…

The increase of knowledge regarding the topic altering genes has become rapid and have open and paved the hope of designing your own perfect baby. Even today, the use of reforming and adjusting the genes of an unborn child is being put in effect. “Techniques of genetic screening are already being used, whereby embryos can be selected by sex and checked for certain disease-bearing genes. This can lead to either the termination of a pregnancy, or if analyzed at a pre-implantation stage when using…

In Vitro Fertilization is defined as a technique for conception of a human embryo outside the mother’s body. In this procedure, several eggs are removed from the mother’s body and placed in a petri dish. Then, sperm from the father are added or injected directly into an egg. If fertilization is successful, the fertilized egg is either transferred to the mother’s or a surrogate mother’s body or frozen for later implantation (Andrews and Henig 1). Since its development, critics of in vitro…

Surrogacy is when a woman carries a child for a couple who cannot conceive or carry a pregnancy to term. In today’s age, surrogacy is mainly agreed upon through a contract, but the idea of surrogacy has been around for centuries and is even talked about in the bible. Surrogacy comes with the ultimate benefit of receiving a child, but there are also many complications that come along with the process. The benefits of surrogacy do not outweigh the complications. There are two main types of…
