Aspects of pregnancy (a)

 Aspects of pregnancy (a)
during fertilization, the sperm will be in the female body through some arduous trek. Their goal is to survive in a limited period through the cervix, and ultimately with the egg. Millions of sperm in the , only one can fertilize an egg. spermatozoa Once that barrier over the cervix, and it starts a new journey.

following about 40 weeks, the mother will experience a series of changes, a new life to provide nutrition and growth space. zygote will change mm from a small group of cells develop into a free breathing, living baby.
article will take you deep inside the uterus, the fetus during pregnancy awareness development and changes in each pregnancy, to understand how the baby finally came into the world, and describes the problems that may occur during pregnancy.
infertility
in About ten percent of American couples of reproductive age suffer from infertility by, one or both of them have a problem with the reproductive system, making it difficult or impossible to conceive [reference]. If a couple in the case of unprotected intercourse under more than one year of life is still not pregnant, are considered to belong to infertility.
infertility cases,UGG boots clearance, caused by the man about four into. You Sicheng blame the other woman, and the remaining two into the fine out of both sides eggs with questions or for some unknown reason. The good news is, there are a variety of methods of infertility treatment, including IVF and medication.
is a major decision to establish a family must plan ahead mm. Health experts suggest that pregnant women should be prepared to go to the hospital for pre-pregnancy obstetric or gynecological examination to determine their own bodies for this task.
typical examination, the doctor will:
understanding history, understanding of the woman is suffering from any disease that may endanger pregnancy (such as diabetes or high blood pressure);
to understand family history and genetic testing to identify whether I have any genetic disease;
physical examination, including infectious check to see if people with herpes and other sexually transmitted disease or urinary tract infections.
check the mother's overall immune function (especially chicken pox and rubella immunization), the two diseases can cause miscarriage or birth defects.
women planning a pregnancy should be noted that dietary nutrition, every day required to take pregnancy vitamins. daily intake of less than 400 micrograms of folic acid can significantly reduce the incidence of birth defects. They should also quit smoking, otherwise it will lead to lighter birth weight and other complications.
Now let solution the process of opening the secret of conception.
men will be released every ejaculation, millions of sperm. sperm into the female body, full speed ahead immediately,cheap UGG boots, urgently pushed around to look for eggs. Once one sperm to find the target and through the wall into the room, then complete fertilization.
Subsequently, in the uterus and everything will be quick step by step. sperm and egg combine to form a single fertilized egg is called the cell body, which contains sperm from the man from the woman's 23 chromosomes and egg 23 chromosomes. these chromosomes determines the baby will have blonde hair or brown hair, blue eyes or brown eyes, and also determine the baby's sex.

some women become aware of a pregnancy can immediately mm can call it a new mother's intuition. However, the pregnancy test is The only way to confirm the pregnancy. All pregnancy tests are the same thing: looking for human chorionic gonadotropin (hCG), an only hormone produced during pregnancy.
home pregnancy tests are urine hCG, and Blood samples were drawn hospitals to be checked. blood test can detect very low concentrations of hormones, so they can determine if earlier than the home pregnancy test. Of course, if the method is correct, the accuracy of home testing up to 97% 至 99%.
early pregnancy: from fertilized egg to fertilized embryo
remember it? this small group of cells to keep dividing until they reach about 100 cells. At this point fertilized egg to become a blastocyst. inner cells will form embryo. outer cells form the placenta, providing nutrients for the embryo.
pregnant three weeks after embryo implantation in the uterus wall and the release of hCG. blastocyst implantation only occurs within a few days after conception. Although conception usually occur two weeks after the last menstrual period, but the doctor used to calculate from the last menstrual period began pre-production of the mother.
fertilized egg along the oviduct to the uterus, and in this implantation.
the fifth week of pregnancy, the brain, spinal cord, heart and other organs have begun to take shape. At this point, the embryo formed by the three layers: ectoderm, mesoderm and endoderm. all the organs and tissues made by the three differentiation. ectoderm will form the nervous system and spine ; mesoderm form the heart and circulatory system; and the formation of the lung endoderm, gastrointestinal tract, thyroid, liver and pancreas. umbilical cord and placenta has started to form an embryo mm growing access to nutrition through the umbilical cord, discharge of waste. < br> ADAM

the size of sesame seeds, the mother may start to feel the pain of a pregnancy. morning sickness, frequent urination, lethargy, appetite or anorexia is common reaction. chest will swell softened. Some women began to gain weight, but there are some but due to morning sickness and weight loss. By this time, it should be acceptable to obstetric or gynecological first antenatal visit. to the fifth week , ultrasound may detect fetal heart.
mothers during early pregnancy to be especially careful, because the fetus's vital organs are formed during this period. pregnant women should avoid alcohol,UGG bailey button, certain medications, caffeine and cigarettes. In addition, should continue taking prenatal vitamins containing folic acid, to maintain a healthy diet and regular exercise.
early pregnancy: from embryo to fetus
9-12 weeks of pregnancy, age over 35 and have had family history of chromosomal abnormalities in pregnant women need accepted chorionic sampling (CVS) examination. This test used for screening for Down syndrome and other chromosomal abnormalities. The doctor will use ultrasound guidance, take out a small piece of placental tissue for testing.
obstetric or gynecological doctor to ultrasound for the guidance,

early pregnancy in the last few weeks, the embryo started to really take shape. facial contours gradually become legible. neural tube, which is future brain and spinal cord, also began to develop. granulation eruption of small, gradually become arms and legs.
about 8 weeks of pregnancy, the embryo into a fetus. kidney, liver, brain and lungs began to play all of their functions. fingers and toes begin to differentiate, the formation of external genitalia. 12 weeks of pregnancy, the fetus of about 7.6 cm long and weighing about 28.4 grams. As early as the end of pregnancy, most pregnant women will feel more and more tight clothes, but still a little too maternity wear premature.

abortion
to about 15% of pregnancies Most ended in abortion in early pregnancy mm. as many as half of the pregnancies ended in abortion may be, but many occur very early, and realized that none of the parties have had a pregnancy.
most of the termination of pregnancy because of chromosomal abnormalities, the problem may have come from the egg, may also be derived from the sperm. older than 35 years of age and pregnant women, abortion appears the possibility of chromosomal abnormalities is much higher than younger people. Other factors that lead to abortion include infection, hormonal problems or maternal diseases (such as diabetes). drinking, smoking and misuse of drugs will increase the risk. Fortunately, most of the women after one miscarriage, there are still opportunities for the future health of pregnant normal baby unharmed.
