No, the heart rate cannot predict the sex of your baby. You can even see and measure this flicker of light on an ultrasound. The beats per minute bpm start at a slow 90 to bpm and increase daily. They continue to increase until they peak around week 9 , between and bpm for boys and girls alike. Still, you can find lots of forum topics across the web on this subject. Though many women swear heart rate clued them in, the overall results are mixed at best.

What baby? This concept may be a little hard to wrap your head around, but even though you're technically in the first week of pregnancy, you're not quite expecting -- yet. Here's the deal: Because it's generally impossible to know the exact moment of conception, most healthcare providers count 40 weeks from the first day of your last menstrual period LMP to calculate your due date.

According to this method, they date the beginning of "pregnancy" from about two weeks before the sperm penetrates the egg -- which is where you are right now. Already spotted that pink line on a home pregnancy test?

You're further along than you think, so skip ahead to Week 4. So far your baby doesn't exist, but this is the week you ovulate. Your ovary releases a ripened egg ovum into your fallopian tube, where it will patiently await the sperm that have survived the 6- to 8-inch trek through your cervix and uterus. While 75 to million sperm embark on this journey, less than a thousand actually make it past your cervix -- and only one lucky swimmer will have the honor of penetrating the egg at the moment of conception.

Amazingly, your child's sex and all of her inherited genetic characteristics -- such as eye color, hair color, skin, and body type -- have been set since the moment of conception. Your developing baby, now called a zygote, has 46 chromosomes -- 23 from you and 23 from your partner. These chromosomes help determine your baby's sex and traits such as eye and hair color, and, to some extent, personality and intelligence.

After fertilization, the ball of cells, now an embryo, will wrap up its journey through the fallopian tube and burrow itself into the wall of your uterus for nourishment -- a process known as implantation.

If you're having multiples, the deed has already been done. Fraternal twins occur when two separate eggs are fertilized by two different sperm and each baby has his own placenta and amniotic sac. If one fertilized egg splits and develops into two fetuses, the result is identical twins. They may share a placenta, but each baby usually has a separate amniotic sac. So what's going on in your womb this week? Your embryo may be minuscule, but trust us: Super-important developments are already under way.

This week the embryo splits into two parts. One half will become the placenta, a special tissue that delivers must-have nutrients and oxygen to your baby throughout your entire pregnancy.

In the other half, the embryo itself continues to grow, and a sheet of cells has just begun to create the neural tube, where your baby's brain, spinal cord and backbone will ultimately form.

This week, your baby's ticker will start beating for the first time! Neither you nor your doctor can hear it yet, but it may be possible to see the movement on an ultrasound.

And your little one has been really busy growing! The embryo now has three distinct layers: the outer ectoderm, which will form the nervous system, ears, eyes, inner ear and many connective tissues; the endoderm, or inner layer, which will grow into internal organs like the lungs, intestines and bladder; and the middle mesoderm, which will eventually make way for the heart and circulatory system.

In the weeks to come, the mesoderm will also evolve into bones, muscles, kidneys and reproductive organs. By the end of this week your baby will have tripled in size! His heart is now beating with a regular rhythm. It's still too faint to be picked up by your doctor's stethoscope, but if you have an ultrasound at some point over the next few weeks it will probably be visible as a tiny, pulsing dot in the middle of his mini body.

Fun fact: From now until birth , your child's heart will beat about times a minute -- twice the average adult rate. Also this week, your baby's brain hemispheres are forming -- and brain waves can now be recorded. Your baby is already developing amazingly distinct facial features. Dark spots mark the areas where her eyes and nostrils will be, and a little mouth and ears are starting to form, too. Your baby's brain is also growing more complex; if you could take a peek, it would be clearly visible inside the transparent skull.

In fact, nerve cells in your baby's brain are growing at an amazing rate -- , cells per minute! And she's started to move in small, jerky motions, although you won't feel these movements until about your fourth month of pregnancy. Your baby's growth spurt continues: In the last two weeks he has quadrupled in size. As he gets bigger, his delicate facial features are becoming more refined, with his ears, upper lip, and the teeny tip of his nose all clearly visible. His eyelids will also take shape for the first time this week and his heart is growing stronger by the day.

Even though you still have to wait another eight weeks to find out if your new addition will be a boy or a girl, this week, your baby gets the goods she'll need to, well, make her own baby one day.

That's right -- reproductive organs are beginning to form now, along with some other key organs, like the pancreas and gallbladder. At this point your baby has doubled in size and her head, which is about half the length of her entire body, is tucked down toward her chest.

Her tiny fingers are growing longer, and the ends are slightly enlarged right now -- this is where those unique fingerprints will ultimately form. Up until now your baby was classified as an embryo, but by the end of this week he will be a fetus and lots of changes are on the way.

Paddle-like, or webbed, hands and feet will now separate into fingers and toes, bones will begin to harden and his kidneys are now producing urine. Most impressive? At this point your baby's brain is developing at astounding rates -- nearly , neurons are forming every minute! The end of the embryonic stage also marks a turning point for development dangers -- your baby is much less susceptible to them now.

Did you know your baby can breathe underwater? She's doing it right now. At weeks 10 and 11, the fetus will start to inhale and exhale small amounts of amniotic fluid, which helps your baby's lungs to grow and develop.

Also this week, your baby's ears are scooting up to the sides of his head. Sure, your baby's head is still disproportionally large compared to the rest of his body, but this will even out as he continues to grow and develop in the womb. As your baby's muscles start to bulk up at this stage, he's getting busy stretching and kicking. When you put your hand on your belly, your baby will likely wiggle in response because his reflexes are starting to develop -- though it's too early to feel his movements.

He'll also start to open and close his fingers, curl his toes, and jerk and kick his arms and legs. Your baby is constantly getting bigger and cuter, and his face is looking more human-like every day. His ears have moved up from his neck into place and his eyes -- which are looking more and more like your baby blues or browns, or greens -- have moved from the sides of the head to the front of the face. Up until now, his head has been outpacing his body, but now his body is growing faster.

His legs still need to grow longer, but this week his arms will lengthen to be proportionate with his body, and he'll be able to stick his thumb in his mouth. Also by now, all of your baby's essential organs and systems have formed. The roof of your baby's tiny mouth is fully formed now, and her constant sucking reflexes are helping to create full, cherubic cheeks. If you're having a boy, the prostate is forming, and if you're having a girl, her ovaries are moving down into her pelvis.

Lanugo, your baby's first ultrafine, downy hair, now covers his back, shoulders, ears, and forehead. It helps him retain body heat, but once he gains enough fat to do the job, this hair will fall off -- probably before birth. Facial expressions are your baby's newest trick -- he can frown, squint, grimace and wince.

Don't worry -- he's just flexing his facial muscles, not indicating his mood. Your baby's delicate skeleton continues to harden from rubbery cartilage to bone. Even so, his bones will remain somewhat flexible for an easier trip through the birth canal. The umbilical cord has fully matured with one vein and two arteries that are protected by Wharton's jelly a thick substance that makes the cord slippery so it can move freely around your baby.

By the way, if you're having a girl, hundreds of thousands of eggs are forming in her ovaries this week -- your future grandchildren! Finally, your baby's arms, legs, and trunk have caught up to the size of his head. Baby starts plumping up this week, as body fat is deposited under his skin and sweat glands develop. Also worth noting: The placenta is almost as big as your baby.

It provides vitamins, minerals, proteins, fats, and oxygen, along with removing waste and filtering carbon dioxide. Do you and your partner talk to your baby? Well, with the bones and nerves in her ears now developed enough to function, she can hear all sorts of sounds -- including blood coursing through the umbilical cord, your growling tummy, and your heartbeat.

In fact, sudden or loud noises may startle her. Go ahead and sing, tell stories or play music for your baby now. Even though your baby doesn't understand what these sounds are now, eventually she'll recognize your voice better than any other.

Vernix caseosa begins to coat the skin. The greasy, cheese-like white coating helps regulate body temperature and protects your baby's skin while it's submerged in amniotic fluid. By the time your baby is born, most of the vernix will be gone. Your baby's heartbeat is growing stronger now and it's about twice as fast as yours. Your baby is as happy as a clam in your womb, as his well-developed limbs continue to explore by curling, flexing, and kicking.

And as his hair, nails and eyebrows continue to sprout, your fetus is looking remarkably more and more like Mom and Dad every day. Part of your baby's growth spurt at this point is likely because his stomach is now equipped to start absorbing energy-boosting nutrients from the amniotic fluid he's swallowing in there. Most of your baby's nourishment is still coming directly from the placenta, though.

Your baby's previously see-through skin will now become opaque. However, it will remain wrinkly, red, and covered in vernix until more fat helps to fill it out. Also this week, he's fine-tuning his sense of touch thanks to maturing brain cells and nerve endings. Your baby may experiment with these newfound skills by feeling his face or anything else he can get his hands on.

This week, your baby's eyebrows start growing and hair will start sprouting on the scalp, but this varies -- your baby may grow a thick head of dark hair or he may enter the world bald.

Billions of brain cells will develop in your baby's brain over the next couple of weeks. These will control all of your baby's movements and sensory, and basic life functions like breathing. Also around this time, some major changes are happening with your baby's lungs. Surfactant is being produced, a substance that enables the air sacs to inflate and the lungs to fully expand.

Right now he's still breathing amniotic fluid, but when he's born he'll be ready for air.

Fetal Development: Your Baby’s Sex

Embryos with XY chromosomes become boys, and those with XX chromosomes become girls. That means that all our sex organs come from the same foundations: The testes in men are equivalent to labia and ovaries in women, and the penis is the equivalent of the clitoris. At around week 7 , the Y chromosome signals for the start of testosterone production, and male genitalia begin to develop.

Fertility Throughout Life by Lexi Krock Fetus Male: By the tenth week of pregnancy, a fetus's gender is evident, and by week 14 sex organs have formed. Female: At 20 weeks, a female fetus has a fully developed reproductive system, replete with six to seven million eggs.

A Newcastle University study involving thousands of families is helping prospective parents work out whether they are likely to have sons or daughters. The work by Corry Gellatly, a research scientist at the university, has shown that men inherit a tendency to have more sons or more daughters from their parents. This means that a man with many brothers is more likely to have sons, while a man with many sisters is more likely to have daughters. The research involved a study of family trees containing information on , people from North America and Europe going back to

Sex selection: Getting the baby you want

If a pregnant woman has a neat bump that sticks out in front like a netball, then it is a boy. If the weight is more spread out around her middle then it is a girl. Or so they say. As any mother will tell you, there is no shortage of family members and friends offering folk stories about how to tell the sex of your baby during pregnancy. The first is the size of the baby. It is true that on average baby boys weigh more at birth than baby girls, and so this could make the bump for a boy slightly bigger. But this small difference in weight does not change the shape of the bump. The second is the position of the foetus in the womb.

Baby Heart Rate and Gender: Can It Predict the Sex of Your Baby?

Are you having a girl or boy? The sex reveal is probably one of the most exciting parts of your pregnancy. But is there any way to learn the answer without an ultrasound? How accurate are all of those stories about sex prediction, anyway?

Although the evidence is not yet extensive enough to be conclusive, analysis of genetic mechanisms seems to suggest that whether a certain couple will give birth to a boy versus a girl may not be completely random i.

We sit around a glass coffee table. The room is clean and modern, the furnishings are that chicken soup colour favoured by architects — and expensive private clinics. Which is just where they are heading. The Gunns want a baby girl.

Myths vs. Facts: Signs You’re Having a Baby Girl

The birth of Rekha's second daughter should have been one of the happiest days of her life. Instead, she lay on the bed of her home on the outskirts of Delhi, the newborn child on the floor, screaming in terror as her mother-in-law poured paraffin over her. This was her punishment, the older woman said, preparing to strike a match: Rekha had failed again to deliver a son and it would be better for everyone if she were dead. Suddenly the door burst open and her neighbours rushed in, roused by the frantic screaming. They bundled Rekha and her daughter out of the house, never to return. In a country where boys remain prized and having a daughter is considered by many to be a curse, they were lucky.

Is it completely random whether a baby is a boy or a girl?

Gone are the days when gender prediction meant taking the word of the wise old lady in the village. We spoke to Pranjul Tandon, Childbirth educator and newborn care coach at Wombandbeyond. Fact: Although this might sound scientific, several studies have been done to compare fetal heart rates between genders during pregnancy, with no significant correlations or contrasts found. Intriguingly a study did find that female fetuses having a significantly higher heart rate during normal labour than male fetuses, but the reasons for this are unknown. Myth: If your bump is protruding like the shape of a ball, it is a boy. While boy babies do tend to be slightly heavier than girl babies, this would only affect the size, rather than the shape, of your bump. Fact : There is actually potentially some truth to this one. A study of over a million pregnancies in Sweden between and showed there was a greater risk of the serious morning sickness condition known as hyperemesis gravidarum in the first trimester for women who were carrying a female child.

Female: At birth, a girl's pair of ovaries contain up to 1,, follicles, which menstrual cycles, men are constantly fertile from the onset of puberty (usually at.

Beware, pregnant moms. From the moment you tell your friends or begin showing signs of a wee baby bump, the congratulations you receive will be uttered in the same sentence as, "Are you having a boy or girl? Perhaps this is our desire to envision a complete little person before the birth, a need to begin attributing characteristics, consider names, and find the perfect blue booties or pink layette. Sometimes curiosity about a baby's gender leads to some gender-guessing games that may have moms-to-be wondering: Is there any truth to those old wives' tales? Kelly Leggett, the medical director at the Women's Hospital of Greensboro.

We can't offer any guarantees, but hey, there's no harm in trying! Are you desperate for a boy or a girl baby? Just remember, the information here is just a guide, a bit of fun. It is always the man who determines the sex of the baby.
