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!
