If you’re dying to know whether to stock up on pink or blue onesies , you’ll likely have to wait until you’re about 18 to 20 weeks along. Doctors can usually determine the baby’s sex during a routine ultrasound visit at this time, but not always. The position of the baby during the ultrasound is key, and if your baby’s curled up or facing the wrong way, you may have to wait until your next appointment. For obvious reasons, it’s usually easier to see if your baby is a boy. The test, usually given to moms 35 or older, involves inserting a needle into the uterus to remove a small amount of amniotic fluid. This test isn’t without risk, however, and isn’t performed simply to determine the sex of your baby. Another test that can look at the baby’s chromosomes is called CVS chorionic villus sampling , which is performed during the first trimester to look for problems with the baby’s chromosomes. However, this test is infrequently used. I’m often asked if you can tell the baby’s sex by the heart rate—based on the myth that one sex is faster than another—but that’s just an old wives’ tale. Some people claim they can predict the baby’s sex by the way you’re carrying, but, again, there is no scientific proof that this is true.
Prostate cancer can often be found before symptoms start by testing the amount of prostate-specific antigen (PSA) in a man’s blood. Another way to find prostate cancer is the digital rectal exam (DRE), in which the doctor puts a gloved, lubricated finger into the rectum to feel the prostate gland.
You may have chosen to have an early pregnancy scan sometimes called viability or early scan to either confirm you are pregnant or to find out if you are still pregnant. Most of the time, the scan will be able to reassure you at the time it is carried out, that you have an on-going pregnancy and all is well. Occasionally, it is not easy to see clearly if your pregnancy is a viable one and, more sadly in a few pregnancies, the scan will show you that the baby has died and the pregnancy will not continue.
A dating scan sometimes called a booking scan will tell you how many weeks pregnant you are and if you are having one or more babies. Like an early pregnancy scan, it will also tell you if your pregnancy is ongoing or not. The NT measurement is undertaken with ultrasound and combined with serum protein markers in the blood to give a combined risk factor. If the screen is positive, then an invasive procedure is offered in the form of either amniocentesis or CVS sampling.
Advances in research have enabled a new Non Invasive Prenatal Test or NIPT to provide more accurate results and higher detection rates during pregnancy. In , it was reported that fetal DNA was present in the maternal blood deriving from the placenta and that it could be detected as early as the first trimester onwards. In addition, fetal blood group status and fetal sexing are also identifiable from maternal blood samples. Further research has also shown that fetuses with Down Syndrome have a higher concentration of fetal DNA within maternal blood making it a reliable method of detection.
Current research shows that a pregnant woman from 10 week’s gestation is the earliest time for blood collection.

A trans-vaginal probe is used for this examination. The scan will provide the following information: Seeing the heart beating is reassuring and confirms that the baby is okay. Determination of chorionicity in twin pregnancy identical twins for example can be made early and extra surveillance of these high risk pregnancies can be organized to optimize the outcome. Ensure an intra-uterine pregnancy. It confirms that the fetus is well placed in the womb and therefore excludes an out-of-place or ectopic pregnancy.
Concerns Regarding Early Fetal Development
With transvaginal ultrasound, checking for embryonic development known to occur within a certain time frame more accurately dates a pregnancy. Transvaginal ultrasound can see embryonic development about a week before transabdominal ultrasound, the American Pregnancy Association APA states. Process A transducer, a wand-shaped probe, is inserted into the vagina and pressed against the vaginal walls directly next to the uterus.
It records high-frequency sound waves that create an image see Reference 4. Normally, ultrasounds before until week 4 of pregnancy shows nothing in the uterus and serve no purpose. Pregnancy is dated from the first day of the last menstrual period, so at four weeks, a woman is just due for a menstrual period.
Sometimes when you have a scan, the findings are inconclusive and you may be asked to go back for a second scan. Waiting for this can be worrying but remember that most pregnancies are successful and you will probably find all is well when you go back for a second scan.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.
You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.
Any woman of any age can have a baby with a chromosomal abnormality. Although the chance of the baby having a chromosomal abnormality is small it does increase as women get older. Your doctor can give you information about your chances based on age.
Opt out or contact us anytime One group was instructed to spend 90 minutes a week doing pleasant and familiar activities, like dining out or going to a movie. The third group was not assigned any particular activity. After 10 weeks, the couples again took tests to gauge the quality of their relationships. Advertisement Continue reading the main story More recently, Dr. Aron and colleagues have created laboratory experiments to test the effects of novelty on marriage.
In one set of experiments, some couples are assigned a mundane task that involves simply walking back and forth across a room. Other couples, however, take part in a more challenging exercise — their wrists and ankles are bound together as they crawl back and forth pushing a ball. Aron cautions that novelty alone is probably not enough to save a marriage in crisis. But for couples who have a reasonably good but slightly dull relationship, novelty may help reignite old sparks. And recent brain-scan studies show that romantic love really can last years into a marriage.
Last week, at the Society for Personality and Social Psychology conference in Albuquerque, researchers presented brain-scan data on several men and women who had been married for 10 or more years. Interviews and questionnaires suggested they were still intensely in love with their partners. Brain scans confirmed it, showing increased brain activity associated with romantic love when the subjects saw pictures of their spouses.
