Expectant mothers have bigger appetites on average if they are carrying a boy rather than a girl, suggests a study of pregnant US wome

A child’s gender (male or female) is determined by the chromosome that the male parent contributes Females have XX sex chromosomes Males have XY sex chromosomes A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome

It’s all about Dad’s genes A man’s X and a woman’s X combine to become a girl, and a man’s Y combines with a woman’s X to become a boy But if the sperm don’t have equal Xs and Ys, or if other genetic factors are at play, it can affect the sex rati

The baking soda gender test is an at-home method that involves combining a pregnant woman’s urine with baking soda to see if it fizzes Whether or not the urine fizzes is supposed to determine whether the baby is male or female The baking soda gender test actually looks to determine the baby’s sex, not its gende

Screening kits, like the Pink or Blue Early DNA Pregnancy Test, look for the presence of the male Y chromosome in a few drops of blood taken through a finger prick If it’s there, you’re having a boy; if not, it’s a girl

Most doctors schedule an ultrasound at around 18 to 21 weeks, but the sex may be determined by ultrasound as early as 14 weeks

The test by Consumer Genetics requires customers to sign a waiver A simple blood test that can determine a baby’s sex as early as seven weeks into pregnancy is highly accurate if used correctly, according to a new stud

You may have heard that your baby’s heart rate can predict their sex as early as the first trimester If it’s over 140 bpm, you’re having a baby girl Below 140 bpm, you’re carrying a boy The truth is, your baby’s heart will likely start beating sometime around week 6 of your pregnancy

Fact: A normal fetal heart rate is between 120 and 160 beats per minute (bpm), although some people think if it’s faster (usually above thee) it’s a girl and if it’s slower it’s a boy But studies don’t show that heart rate is a reliable predictor for a baby’s gender

If the fetal heart rate is under 140 beats per minute (BPM), it’s a boy

A rapid fetal heart rate is termed a fetal tachycardia and is usually defined as: FHR >bpm FHR around 170 bpm may be classified as borderline fetal tachycardia

Many myths surround the sex of an unborn baby One is that, early in pregnancy, unborn boys have faster heartbeats than girls There is no evidence that this is true Studies have shown that there is no difference between male and female fetal heart rate

How does tachyarrhythmia affect my baby? By 16 weeks of pregnancy, the fetus’ heart is normally completely formed and beats at a rate of 110 to 160 beats per minute (bpm) Fetal tachyarrhythmia is generally defined as a heart rate that exceeds 180 to 200 beats per minute

Fetal tachycardia is defined as a heart rate greater than beats per minute (bpm) This rapid rate may have a regular or irregular rhythm which may be intermittent or sustained A sustained fetal tachyarrhythmia is uncommon, affecting fewer than 1% of all pregnancies

During pregnancy, the amount of blood pumped by the heart (cardiac output) increases by 30 to 50% As cardiac output increases, the heart rate at rest speeds up from a normal prepregnancy rate of about 70 beats per minute to 80 or 90 beats per minute
