The document summarizes various techniques for selecting a baby's gender, ranging from most effective to least effective. The most effective techniques include in vitro fertilization (IVF), artificial insemination (AI), and preimplantation genetic diagnosis (PGD). IVF and PGD allow for testing and selecting embryos of the desired gender, but they are also the most expensive and invasive options.

3.  According to our research, there are several
gender selection techniques, and the following
were arrange from the most effective up to
least effective.

4.  IVF
 AI(artificial insemination) also known as
IUI-intrauterine insemination
◦ For IUI, your doctor will use a catheter to insert a
concentrated sperm sample directly into your uterus.

5.  PGD was introduced back in 1989, it was used
solely to help couples or individuals with serious
genetic disorders reduce their risk of having a
child who suffered from the same condition.
Today PGD is still used for this reason, but is
also used commonly when women are 35 or older
and/or have a history of recurrent miscarriage.
Only a handful of clinics offer the technique
for sex selection for nonmedical reasons.

6.  PGD, the embryos are tested thoroughly for
genetic abnormalities and sex. By transferring
only healthy embryos to the uterus, you're less
likely to miscarry or have a child with a genetic
disorder. Prenatal tests such as amniocentesis
or chorionic villus sampling (CVS) are still
recommended if you're 35 or older because
more genetic abnormalities can be detected
later in pregnancy.

7.  Doctors transfer no more than two because
they've already weeded out embryos that are
unlikely to implant or to result in a healthy
pregnancy unlike in IVF.
 100% effective
 Cost nearly $20,000

8.  The procedure is invasive and the removal of eggs from your
ovaries can be painful.
 The fertility drugs you have to take can have uncomfortable
side effects such as weight gain, bloating, swelling, and
blurred vision.
 As with any IVF pregnancy, you're more likely to have
multiple births. According to the latest statistics from the
Centers for Disease Control and Prevention, 38 percent of
infants conceived as a result of IVF and related procedures
were twins.
 About 43% of fresh IVF cycles result in a live birth, and that
figure goes down as you get older. But some doctors claim
higher success rates with PGD because defective embryos
are excluded.
 You'll need to decide what to do with the embryos of the
undesired gender: freeze, destroy, or donate for other
couples or research.

9.  Most fertility clinics that provide PGD don't
allow it to be used solely for sex selection. You
must have a medical reason such as a family
history of genetic diseases or repeat
miscarriages, or be over a certain age, usually
about 38, to qualify for the procedure.

10. Adye technique that attempts to
segregate girl-producing sperm
from the boy-producing variety.
Sperm of the desired gender is
inserted directly into your uterus,
usually via artificial insemination
(AI).

11.  Artificial insemination poses virtually no health
risks and is cheaper than IVF. But you may have to
take fertility drugs, which can cause side effects
and increase your chances of having multiples.
 Because the method typically uses AI instead of
IVF, you don't have to worry about what to do with
extra embryos.
 MicroSort can also be used to try and prevent the
transmission of X-linked disorders — diseases that
moms carry and can transfer to boy babies but not
girls, such as hemophilia and Duchenne's muscular
dystrophy. It lowers the risk of transmitting these
disorders but isn't 100 percent effective.

12.  Effectiveness-The method is about 90 percent
successful when it comes to choosing girls and
about 74 percent successful for boys. These
rates are per pregnancy, not per cycle.

13.  The procedure is still being tested in clinical trials
and hasn't been approved by the Food and Drug
Administration.
 Since MicroSort is relatively new (it's been
available since 1995 and as of January 2004, more
than 500 pregnancies had been achieved), little is
known about possible risks.
 MicroSort can't guarantee a specific gender
because the technology doesn't completely exclude
sperm of the unwanted sex.
 The pregnancy rate for each artificial insemination
cycle is modest — 16.6 percent. With IVF, the
pregnancy rate is 43 percent.

14.  Cost
Approximately $3,000 per treatment cycle if AI is
used. Fertility drugs can increase the cost by another
$2,000. IVF adds an average $12,400 to the cost of
each cycle.
Availability
To qualify for MicroSort's program, you must be
married and have at least one child and want a child of
the opposite gender. You, or your egg donor, must be 39
or younger.
There are two MicroSort centers: The Genetics and
IVF Institute has a MicroSort clinic in Fairfax, Virginia.
Telephone: (800) 277-6607. The second clinic is in
Laguna Hills, California, and operates in partnership
with the Huntington Reproductive Center. Telephone:
(866) 472-4483.

15.  A technique that aims to separate faster-
swimming boy-producing sperm from slower-
swimming girl-producing sperm. Sperm of the
desired gender are inserted directly into your
uterus via artificial insemination (AI).

16.  This technique, which has been around since
the '70s, attempts to separate boy and girl
sperm by pouring a sperm sample on a gluey
layer of fluid in a test tube. All the sperm
naturally swim down, but the boys tend to swim
faster and reach the bottom earlier. Once the
fast and slow swimmers are separated, you're
inseminated with the sperm that will enable you
to conceive the gender you desire.

17.  Effectiveness
Ericsson claims his technique is 78 to 85%
effective when it comes to choosing boys and
73 to 75% effective for girl babies.
 Inexpensive compared to higher-tech
methods.
 Approximately $600 per insemination.
 Noninvasive.
 Relatively safe.

18.  There's no guarantee of success. The
technique's pioneer, Ronald Ericsson, has
published extensively and claims a success rate
of approximately 75 to 80 percent. But some
fertility doctors dispute this figure and say
that it's no higher than 50 percent.
 AI is not as effective as in vitro fertilization
(IVF), and it may take many cycles to achieve a
pregnancy, depending on your age and fertility.

19.  Available to anyone who wants it at clinics in
California, Michigan, Texas, Connecticut,
Montana, Washington, Florida, New Mexico,
Maine, and New York.

20.  CVS is one of the earliest tests performed,
and it does carry risk factors for miscarriage.
Most women undergo CVS if they are at high
risk for having children with severe medical
problems or genetic anomalies, not because
they wish to use the sampling as a gender
prediction test.

21.  In CVS a small amount of placenta material is
carefully removed from the uterus. The
placenta sampling is usually taken during the
later part of the first trimester of pregnancy
and. Since chromosomes are analyzed, CVS
can accurately predict a child’s gender by
detecting the presence of Y chromosomes.
When these are absent, chances are you are
having a girl.

22.  Amniocentesis is not used as a gender
prediction test but to detect possible
problems with the baby. This is normally
performed between the 16th and 20th week
of pregnancy and analyzes a small amount of
amniotic fluid to look for chromosomal
problems. It can detect presence of Y
chromosomes.
 Ultrasounds will most reliably predict gender
after the 18th week.
 Occasionally, an ultrasound is inaccurate.

23. There are still various
techniques to be consider that
can be provide at home

24. Dr. Shettle

25.  The theory is that sperm bearing Y
chromosomes (for boys) move faster but don't
live as long as sperm that carry X chromosomes
(for girls). So if you want a boy, the Shettles
method argues, you should have sex as close as
possible to ovulation. If you want a girl, you
should have sex two to four days before you
ovulate.
 Timed intercourse on specific days of your
cycle.

26.  Effectiveness
Shettles proponents claim the technique is 75
percent effective, but other experts dispute
this. Keep in mind that you always have about a
50 percent chance of conceiving the sex you
want.
Requires no drugs or invasive medical
procedures.
 Free or low cost.
 Relatively safe.

27.  You must take your basal body temperature
every day to figure out when you're ovulating,
or use an ovulation prediction kit.
 There's no guarantee of success.
Availability
-anyone can try it.

28.  Timed intercourse on specific days of your cycle.
 The Whelan method directly contradicts the
Shettles method. The theory here is that
biochemical changes that may favor boy-producing
sperm occur earlier in a woman's cycle. So if you
want a boy, you should have intercourse four to six
days before your basal body temperature goes up.
If you want a girl you should have sex two to three
days before you ovulate.

29.  Effectiveness
Whelan claims her technique is 68 percent
effective for boys and 56 percent effective
for girls, but many experts dispute this. Keep in
mind that you always have a 50 percent chance
of conceiving the sex you want.
 Requires no drugs or invasive medical
procedures.
 Free or low cost.
 Safe.

30.  You must take your basal body temperature
every day to figure out when you're ovulating,
or use an ovulation prediction kit.
 There's no guarantee of success.
 Availability
◦ Anyone can try it.

31.  First up: Picking the right sexual position.
If you want a boy, people have suggested the
following positions:
◦ Standing up
◦ From behind
◦ With the woman just kinda lying there

At least one of those comes with a theory that kinda,
sorta, remotely might work. The thought is that with
the woman just kinda lying there, the sperm are
having an unobstructed, interference-free race to
the egg... so the faster boy sperm can get there first.

32.  Cowgirl style position is where the woman is
on top of the man allowing for deep
penetration and optimum chance for the Y
chromosome sperm to fertilize the egg
resulting in a boy.
 Plough sex style is like the missionary
position with the man on top except the
woman's knees rest over the man's shoulder.
The idea behind this is deep penetration
giving the sperm with the Y chromosome an
advantage.

33.  The theory here is that whichever gender
hits orgasm first dictates the sex of the
child conceived -- so if man goes first, it'll be
a boy; if the woman goes first, it'll be a girl.
I find myself wholeheartedly skeptical about
this... I mean, if this were true, wouldn't
99.994 percent of the babies in the world be
male. Whoa! (Must... exorcise... the Leno.)

34.  Chinese Conception Chart
◦ The Chinese conception chart or gender predictor
chart is said to have been discovered in a tomb and is
supposed to be over 7 centuries old. The chart is
based on the mother's lunar age at the time of
conception and the month of conception. The lunar age
is based on 29 day months. The Chinese gender
prediction chart allows hopeful parents to plug in
dates and ages to determine the sex of the baby.
◦ The Chinese came out with a chart (I've included it
below) where, based on the mother's age and the
month of conception, they predict the gender.

36.  The most common myth also says that mother's
heart rate will identify the baby gender and also
predict by gender predictor chart. If your
heartbeat rate fewer than 140 beats per minute
means you'll have son, and if over 140 beats per
minute you'll have daughter.
 Actually this myth has been disregard for
decades. But there's a study at University of
Kentucky that find the fetal heartbeat give exact
prediction to 91% of male fetuses and 74% of
female fetuses. So, this myth is the most accurate
prediction for knowing the gender.
