Sperm

Pregnancy is a nine month process and it starts when the sperm penetrates an egg. One and a half days later the single fertilised egg begins to divide. After two to three days there are enough new cells to make the egg the size of a pin head.

Explain that some babies come from their mom’s bellies and stay with that mommy. Then explain that some mom’s need help with raising their baby, so they give their baby to someone else so that they can raise it and love it. Explain that all babies are loved, and that they just take different paths towards finding the family that they were made for.

Biological development of a fetus is vary rapid and complex over the nine-month period in the womb. When both the male spermatozoon and the female ovum combine it forms what is called a zygote which holds the twenty-three pairs of chromosomes. The zygote or the embryo undergoes cell division and makes its way to the uterine wall to implant itself, this process is completed about ten days after conception. By the end of the eighth week the organ systems have formed and human characteristics can start to be noticed. From the eighth week until birth the embryo is now labeled a fetus. Quickening can occur from the sixteenth week until birth, this is where the mother can feel the fetus moving. Around the twenty-second week viability can take place, this is where the fetus can survive outside the womb. The nine-month period of being pregnant is split into different trimesters. With the different trimesters there are different abortion procedures can be used to remove the fetus.

For the next few days, the cells of a zygote divide and multiply into a blastocyst, which travels through the fallopian tubes into the uterus. Part of the blastocyst becomes an embryo, which then turns into a fetus. Although it is a well-known fact that fetuses can not survive out of the womb prior to 24 weeks, pro-lifers believe in life even at the zygote stage. “Since this can be established scientifically by looking at the number of chromosomes present in a fertilized egg, it is enough for the pro-lifer to conclude that abortion (at any stage of pregnancy) is morally akin to murder.”

Even the language of conception and gestation have been hijacked by politics and religious fundamentalists. All unborn are called “fetuses.” This clearly shows the ignorance of basic human biology. The newly fertilized egg is a zygote --- not a fetus and not a human being. It is a few cells with potential but no distinguishing characteristics and no ability to feel anything. A zygote becomes a blastocyst, which is a zygote that has reached a certain number of cells but has not yet stuck to the uterine walls. Five weeks after conception, snug in the uterine tissue it becomes an embryo. It does not become a fetus until it is ten weeks old and has ears and some facial features. Society laughs at people who call zebras “horses” and yet tolerates the word fetus for zygote, blastocyst and embryo. Getting the language right can help laypeople realize that a zygote or blastocyst is not a baby.

The germinal stage marks the beginning of prenatal development when the zygote begins to rapidly divide for one week after conception. However, less than one-half of the zygotes will survive past the first two weeks. The zygotes become more specialized as

Those stages are the Germinal stage, the Embryonic stage, and the Fetal stage. The Germinal Stage is the first stage and it is a two-week period that happens after the sperm and egg cell join together to form a zygote. This process is called conception. After conception, the zygote begins to divide. This turns into into a ball of cells that moves beside the fallopian tube. This travels all the way to the uterus. This process is called implantation and it happens when the cells is placed in the wall of the uterus. This process takes about a week to complete. After the two weeks, the Embryonic stage takes place next. The embryonic stage takes two to eight weeks right after conception. At this point in the process, the ball of cells is now an embryo. In this stage, all the major organs form. The last stage of prenatal development is the Fetal stage. This last eight weeks after conception up to birth. One of the first things to take place is the sex organs begin to form. Next, the bones form, muscles form, and the fetus begins to move. The organ systems also begin to develop and the brain’s size grows. One of the last things to work independently is the respiratory and digestive

This is what potentially creates the baby. After 3 weeks of being fertilized, the embryo is less than 1/10 of an inch. The heart of the baby is now beating. At 4 weeks it is about 1/5 of an inch long. It now has a tale that is its back bone that will disappear in a few weeks. Genes are being turned on and cells are able to talk through chemical messages. 18 weeks after being fertilized, the baby is able to be viewed through an ultra sound and in some cases, able to determine the sex of the baby. The embryo is enabled with two sets of gonads and two sets of tubes which is what can make the baby either a male or female. One pair of chromosomes determines which sex that baby will be. After 29 weeks, it is now a fetus and just over an inch long. The fetus heart beats about twice as many times as an adult heart. There is a 50% increase in blood supply for the mother. Now the mother is ready to give birth. Human births are actually more dangerous than any other mammal. The baby preforms many contortions to fit through the mother's opening and if not able to be born through vaginal birth, the mother will undergo a "C" section. After nine months of carrying another human being inside her stomach and going through labor and painful child birth, the mother is blessed with a beautiful child.

Conception: Out of hundreds of eggs and millions of sperm, only one egg and sperm join together at conception. This process takes place in women fallopian tube. The fertilised egg moves to towards uterus to implant in it for next nine months. During this journey, the zygote divides into 12 to 16 cells before reaching the uterus.

Martin, after careful consideration and researching in unique methods, comes to an overall conclusion that there are cultural influences in the way egg and sperm interactions are presented in textbooks. This conclusion has many serious

Reproductive technology has come a long way in the last twenty years and continues to make expansive advances. The question "where do babies come from" is becoming harder and harder to answer. The response used to sound something like "when a man and a woman love each other very much…" now with in vitro fertilization, fertility drugs, and sperm/egg donors as well as future advances the answer will take on a new twist "…they go to see a doctor and look through a catalog to pick what kind of baby they want."

Life starts out as a fetus in the mother’s womb. This process lasts about 40 weeks. The 40 weeks are broken up into three trimesters. It begins with a stage called conception. This is when the sperm cell fertilizes the egg creating a zygote (the developing individual produced from such a cell). The zygote divides into many cells which is then rooted in the uterus. This is called a fetus
