Human embryo

Luiscolorado: Removed redundant definitions ("In Vitro" and "IVF" are the same thing)

A '''human embryo''' is the first stage of human development.

It is develops by cell multiplication of a zygote, formed by the fusion of the male [[gamete]] (spermatozoon or "[[sperm]]") and female gamete ([[ovum]] or "egg"). This is called [[fertilization]] and usually occurs in the proximal portion of the female reproductive tract. After fertilization, an embryo must implant in the lining of the uterus. If it does not, several problems can occur. The pregnancy can be lost via miscarriage. This often occurs without the knowledge of the mother. A tubal pregnancy can occur. This is a medical emergency requiring prompt intervention.

== Controversies ==

There are several controversial issues involving human embryos.

#IVF, that is, ''In Vitro'' (in glass) Fertilization: Traditionally, fertilization occurs via insemination of a female by a male during sexual intercourse. However, reproductive science has created many advances in fertilization, allowing infertile couples to have their own biological children. This embryo is then surgically implanted in the mother. The first so-called "test tube baby" was born in 1979 and is now a healthy female adult. There has been a great deal of controversy about this practice, and there are many interesting moral/religious viewpoints on the topic. Many see IVF as a way for couples to help fulfill God's commandment to be fruitful and multiply, others see it as science invading the territory of natural marital reproduction.

#[[Abortion]]: abortion interrupts the development of an embryo into a living baby separate from its mother. This issue is addressed in depth elsewhere.

#[[Stem cell]]s: also addressed extensively elsewhere. [[http://www.conservapedia.com/Stem_cell_research]]

Luiscolorado: There is correlation and causation. This is statistically beyond doubt.

Recently, vaccines have been used to deal with sexually transmitted diseases such as the [[HPV]] virus. Some Christian groups have objected to the use of such vaccines on the belief that it will encourage promiscuity in children.

Since doctors began using vaccines, however, many diseases have been curbed. [[Polio]], for example, killed over 3,000 people in the United States in 1952 [http://www.http://www.cdc.gov/nchs/data/vsus/VSUS_1952_2.pdf], and inflicted such noted persons as President [[Franklin Delano Roosevelt]], actor [[Alan Alda]], and musician [[Itzak Perlman]]. When doctors began using a vaccine to fight polio, it practically erradicated the disease in the developed world.

Other diseases that have been curbed since the invention of vaccines include [[smallpox]] (previously a yearly killer of thousands worldwide), [[chicken pox]], [[measles]], [[mumps]], [[rubella]], and [[typhoid]].

Because these diseases were prevalent before the use of vaccines and rare afterwards, many people believe that vaccines may have something to do with preventing the diseases, although correlation does not always necessarily imply causation.
