In the end, families are happy to welcome their healthy new addition regardless of sex. The process through which gender is determined is called human sexual differentiation. All eggs contain an X chromosome, while sperm can have an X or a Y chromosome.
By Linda Geddes. Deciding whether or not to find out the sex of our unborn child was a dilemma that plagued us for weeks. Would it spoil the surprise?
Old and wrong ideas about gender determination hold so much sway that people are constantly doing ridiculous things: Women pee in Draino and men consult the Chinese calendar or measure bumps. That said, many does not mean all. If all is well, the heart rate should fall between and beats per minute.
The guessing game begins almost as soon as you get a positive result on a pregnancy test. Will it be a girl? Or a boy? But folktales are one thing, and science is another.
Metrics details. Previous researchers have studied circadian changes in the fetal heart rate FHR on small sample sizes and in a strictly controlled environment. This study was undertaken to investigate these changes during the late second and third trimesters, using a portable fetal electrocardiogram recording device Monica AN24 in pregnant women in home and hospital environments with unrestricted mobility.

Ultrasounds have a variety of purposes during pregnancy, but the use that often receives the most attention is its ability to reveal the sex of the baby. Some parents-to-be can't wait to find out whether they're having a boy or a girl, while others choose to put off knowing the sex until birth. Either way, a sonogram — the grainy, black-and-white image that results from an ultrasound scan — will be baby's earliest picture and a couple's first chance to see the developing fetus.
Just can't wait to know what colour onesies to buy? For many mums-to-be, knowing whether you are pregnant with a boy or a girl, even in the first trimester, is the great unanswered question. Although the sex of the baby is determined genetically from the minute you conceive, and its sex organs start developing from 11 weeks, it can be a long four-and-a-half months until an ultrasound can actually confirm the gender. Here we look at all the different symptoms you're having a boy, from old wives tales - some more reliable than others - to medical procedures - some safer than others - to see how reliable they are.
By Emily Sadler Jan 25, Every pregnant woman has been asked this question— several times. Cravings for salty or even protein-rich foods mean it might be a boy.
Baby gender testing uses a process known as Polymerase chain reaction to analyze the fetal DNA in the maternal urine. This highly scientific technique for DNA analysis provides highly accurate results in determining the baby gender early in pregnancy. Essentially, what DNA analysts will do is look for male or female DNA, or rather, Y chromosome specific markers or X chromosome specific markers Y chromosome markers indicate you are expecting a boy and X chromosome markers indicate you are expecting a girl. There are many at home baby gender tests.
