Diego's speech outline.

Informative Speech I:

In Vitro Fertilization

Introduction: Hello everyone, my name is Diego Estrada and today I will be talking about one of the most amazing biomedical technologies currently performed in the U.S.

Attention Getter: Do you think that it is legal to create humans in a laboratory?

Preview Statement: According to “The Advanced Fertility Center of Chicago”, In Vitro (IVF) involves taking eggs from the woman, fertilizing them in the laboratory with her partner's sperm and transferring the resulting embryos back to her uterus 3 to 5 days later.

Establish Significance: After trying to get pregnant for more than two years, and going through many different treatments, such as artificial insemination; this was my sister’s final attempt in order to try to get pregnant, and it worked!

Transition to Body:

There are five main steps in order for In Vitro to take place:

1. Hormonal stimulation;

2. Retrieving and storing the eggs;

3. Collecting the sperm from the donor;

4. Insemination of Eggs and Embryo Culture;

5. Transferring Embryos to the Uterus.

Body:

I. Hormonal stimulation:

According to “The Infertility Center of Saint Louis”, the patient must receive daily injections of hormones for months in order to produce more and healthier eggs.

II. Retrieving and storing the eggs:

A. According to the health system of “The University of Alabama” at Birmingham, the physician uses ultrasound images to observe the eggs while he uses a special needle to vacuum them out of the ovaries…

B. Once the eggs are taking out, the three best eggs are used for fertilization immediately, and the remaining eggs are then stored be freezing them with liquid nitrogen. The remaining eggs would be used in the event that the first round of In Vitro fertilization is not successful.

III. Collecting the sperm from the donor:

1. According to “The Georgia Reproductive Specialists”, A semen sample will be obtained from the partner by masturbation or by testicular biopsy on the day of the egg retrieval.
2. Then the best sperm will be selected and ready to be used in the In Vitro fertilization.
3. Abstinence from ejaculation is recommended 2 to 5 days prior to the retrieval of the eggs for better results.

IV. Insemination of Eggs and Embryo Culture:

1. According to “Revolution-Health”, The eggs and sperm are placed in a glass dish and incubated with careful temperature, atmospheric, and infection control for 48 to 120 hours.
2. If everything goes well, the egg will have been fertilized by the sperm and therefore become a new Embryo!

V. Transferring Embryos to the Uterus:

1. According to “Human Fertilization and Embryology Authority”, once the Embryo has divide into 6 to 8 cells, it would be considered to be in its optimal size and ready most likely to continue to grow and therefore it would be chosen to .
2. The physician then uses a needle to introduce the Embryo into the woman’s uterus, resulting in a normal pregnancy.
   

Review Statement and Closing: If the whole In Vitro Fertilization process goes well and the Embryo manages to continue growing properly, the now pregnant woman would be able to give birth to her new baby in about eight and a half months later!

Chap 12

As I was reading this article I realized that I could identify myself with it, because when I read scientific articles I am usually irritated by the fact that I can not comprehend some of the words and as a consequence I get mad and simply stop reading the article. In my case is even harder to understand what a science article is about simply because English is my second language and I do not know most of the high tech words used by scientist to express themselves. If all journalists simply did what this article suggest, and remember that the public does not comprehend all this difficult words, and that the public would like to know the simple steps involved in coming out with a scientific discovery; it would be much easier for me and for many other people to understand and appreciate the whole process of any scientific discovery. I really enjoy being able to understand a simple written report and or article. I would love to be able to spend less time in the dictionary looking for definitions of words that I do not comprehend, and spend more time enjoying and learning new and interesting stuff!

SCIENCE

At first, I was a little disappointed about having to read such long article because I figured this was a speech class, not a reading class, but as I was reading the article I realized that this was not about the typical English class assignment. Instead it caught my attention because it was about improving your writing skills and that is something I can identified myself with. The reason I say this is because I have always had trouble trying to express myself, especially when it comes to writing it down, and this article happens to have amazing tips on bettering this type of problems.

In chapter two, there is a small quote that summarizes what I am trying to pint out:

“Bad grammar, if only occasional, does not destroy one. On the other hand, to communicate effectively you have to be able to produce decent sentence.”

In my case it is easier to say things than having to writing them down. This quote shows that if one could simply write down what is on your mind without having to worry about the grammar, it would be a lot easier for anyone to communicate! In my case this is very true. Sometimes I have great ideas that I can-not share with other simply because I have to write them down, and my ability to write is very poor, but if I simply followed the tips proposed in this article expressing myself through writing would be a lot easier.
