Checkups and Tests During Pregnancy

At 17 weeks of pregnancy, the average biparietal diameter (BPD) is approximately 4.5 to 5.0 centimeters. However, individual measurements can vary based on factors such as fetal position and growth patterns. Ultrasound is typically used to obtain this measurement, providing a way to assess fetal development. Always consult a healthcare provider for the most accurate information regarding fetal growth.

In early pregnancy scans, "diffT6" typically refers to a measurement related to the size or development of the embryo or gestational sac. It may indicate a differential measurement at a specific time point in the gestational timeline, often used to assess growth or to identify potential issues. It's essential to discuss any specific findings or terms with a healthcare provider for accurate interpretation and context.

Amniocentesis involves testing a sample of amniotic fluid surrounding the fetus to examine the fetal cells for genetic abnormalities. In the case of Down syndrome, amniocentesis can identify the presence of an extra copy of chromosome 21 in the fetal cells, which is characteristic of the disorder. This test can provide information about the genetic makeup of the fetus and help diagnose Down syndrome.

A normal human male has two 21st chromosomes and a Down Syndrome male has three 21st chromosomes.

A human female would have the same karotype with regard to chromosome 21 as a male human.

Through the wonders of science, infertile couples who were

previously unable to bear children, due to reasons such as blocked

fallopian tubes, low sperm count, low egg quantities or advanced age

of the mother, are now able to conceive through in-vitro

fertilization. The results are babies known as test-tube babies

which are technically conceived outside the womb.

In a natural scenario, the conception of a baby occurs when the

ovum, travels from the ovaries, through the fallopian tube to be

fertilized by the sperm of the father during sexual intercourse.

From this point on, the fertilized egg will travel down towards the

uterus and during the process division of cells will occur until it

reaches its final destination at the wall of the uterus. However, in

the cases of block fallopian tubes, the eggs are unable to travel

from the ovaries to the uterus and conception cannot happen.

Developed in the United Kingdom by Dr. Patrick Steptoe and Dr.

Robert Edwards, the process of in-vitro fertilization involves

removing eggs from the ovaries of the mother and combining them with

the sperm of the father in a lab environment. The fertilized egg is

then placed back into the uterus of the mother after 3 to 5 days and

will remain there to grow till birth. Because of the low success

pregnancy rate of this procedure, a few eggs are placed in the

uterus to increase the odds of success. With this process,

statistics have shown that the rates of multiple births have

increased where 24 percent of the in-vitro fertilization births have

produced twins.

The first test-tube baby, Louise Brown, who was born on the 25th

July 1978, marked hope for other infertile couples to have a baby

through this procedure. However, many others were concerned about

the ethical issues surround this. One major area of concern was the

fact that as the egg is located outside the womb for a few days

while the cells multiplied before being put back inside the uterus,

the health issues affecting this baby is unknown. Indeed, research

has been shown that test-tube babies have a higher chance of birth

defects and low birth weight, and researchers still have not been

able to determine the reason for this.

Other issue of concern is that through this procedure, some of the

eggs fertilized in the lab are later discarded. Does this procedure

mean that the researchers are actually killing potential people? How

is the line drawn in this case?

Then there is also the issue of commercial opportunities for eggs

and sperms to be bought and surrogate wombs to be rented with the

purpose of creating babies. This process of embryo transfer to

another mother, not necessarily the same woman who had provided the

eggs, is known as placing the embryo in a gestational carrier. This

procedure has been becoming increasingly common through

technological advancement, which has made couples including women

with uterus problems, have a chance in having their baby.

Test-tube babies have really brought changes to the way in which

babies are conceived and have given much hope to many who have had

problems having babies through the process of fake fertilisation. However, the

downside of this are the ethical issues behind the procedure, with

which still poses a big question mark and with which is still

opposed by many factions.

A new test has been developed, called FASTER (First and Second Trimester Evaluation Risk), with which Down syndrome will be able to be detected during the first trimester of the pregnancy - about 11 weeks after conception - with 87% accuracy.

Legally? No.

Its jelly stuff that slide u can see the baby better

There is one pool of blood, so that any sample will have both young and old red blood cells.

A zygote is way too early to test but you can test a fetus but it is too risky so they don't do a amniocentesis just for that. You have to wait until after birth.

Paternity testing can be done online. Your home DNA test kit would be sent to you. The alleged father and child can send the samples to a lab and have results in five to seven days. A standard test will cost less than $200 dollars while a legally binding test will cost less than $400 dollars.

yes you can have a DNA test done while pregnant, but there are risks that you should read upon before choosing this option. The doctor will insert a needle into your stomach to the womb of the baby and take some of the fluid. But, I've heard doctor offices don't do these anymore because it has major risks to the baby.

Hi, The yellow discharge is not pregnancy related hun. This is caused by a yeast infection. You will need to go to your pharmacist for some cream or a pessary for yeast. This will clear it up. You cannot have unprotected sex while you have yeast or you may pass it to your partner and he in turn, can pass it back onto you again. Men do not show symptoms of yeast infections.

If it occurs once, it's a normal variance. If it occurs four month in a row, see a doctor.

CVS involves removing a tiny piece of the placenta and examining the cells.

You should schedule an appointment as soon as you find out. Sometimes it takes a while to get in to a doctor. Start shopping around with doctors. Make sure you feel 100% comfortable with your doctor and you are going to be comfortable and trust them when you are delivering. They will do the first prenatal checkup routine, take blood, ask you a bunch of questions and possibly, but not likely, have an ultrasound.

Amniocentesis is a procedure performed on pregnant women to determine possible risk factors with their developing fetus. A long needle is inserted through the abdomen into the uterus, being guided by an ultrasound, that extracts amniotic fluid. This amniotic fluid is then further tested to determine certain risks such as Down syndrome. Although amniocentesis does have it benefits of obtaining this kind of knowledge, it also poses threats to the fetus such as a .8% chance of miscarriage, clubfeet, trauma to the mother, preterm labor and an infection of the uterus. According to an article published in a Canadian journal, a study in Canada showed that amniocentesis performed between weeks 11 and 13, resulted in 29 out of 4,374 women gave birth to children with clubfeet. Because of this risk, doctors generally try to avoid performing amniocentesis before week 15 of pregnancy.

I suppose it could be however twins usually are indicated by a high hcg level and 720 is not high. Your pregnancy cant even be seen on ultrasound with levels less than 1000 and in most offices they like to do the ultrasounds after the level's above 2000

There is no way to tell unless she takes a test in front of you or shows you a test taken at the doctor. If her stomach starts to get big and round, then she is probably pregnant. Most women start to show at about 4 or 5 months. If you think she is pregnant, you need to ask her. You are as involved with this baby as she is.

Yes. There are several methods including a procedure called amniocentesis in which a needle is inserted into the uterus and a small amount of the amniotic fluid is collected for testing. Recently scientists have discovered a trace presence of the baby's DNA in the mother's own blood stream which can be isolated and tested.
