Choosing Babies SexWill it be a girl or a boy?
Choosing your babies sex
Dr. Landrum Shettles - Pioneer in in vitro fertilization techniques who conducted some of the first experiments in fertilizing a human egg in a laboratory, who developed the GIFT technique for transplantation of a fertilized egg into the fallopian tube, and who spent many years studying ways for couples to choose the sex of their baby including writing the controversial book 'How to Choose the Sex of Your Baby'. This is an extract from his book.
X's and Y's
Basically, men produce two types of sperms, the X
(female) and Y (male). According to Dr. Shettles'
studies the y-sperms are smaller, weaker, but faster
than their sibling x-sperms, which are bigger,
stronger, but slower.
Based on this fact, there are several things you can
do to 'favor' the conception of boys or girls:
Timing of intercourse
The most important aspect of all is timing of
intercourse during the monthly cycle. The closer to
ovulation you have sex, the better the chances to
have a boy, because the y-sperms are faster and tend
to get to the egg first. If you have sex 3 days or
more before ovulation, the better your chances to
conceive a girl, because the weaker y-sperms tend to
die sooner and the x-sperms will be available in
greater quantity whenever the egg is released. On
the other hand, having sex from 2 days before
ovulation, through a few days after ovulation, is
better for conceiving a boy. Around the 2-day point
-- 48 hours before ovulation -- seems to be the 50/50
(For those with a precise turn of mind, Shettles
clarifies even further [p. 187]: from zero to 24
hours before ovulation, intercourse is more likey to
result in a boy; from 24 to 96 hours before, a girl
is more likely; and the further away from that 24-
hour dividing line in either direction, the better
Women's orgasms can also be important. This also
has to do with pH. When a woman has an orgasm, the
body releases a substance that makes the environment
more alkaline, favoring boys. Shettles recommends no
female orgasms when trying for girls!
Position of intercourse
Position of intercourse and depth of penetration
are important, partly because of acidity/alkalinity
of the woman's reproductive tract (see sec. (6)
below). The closer to the entrance to the vagina, the
more acidic the pH of women's tract. Also, deep
penetration places the sperm closer to the egg, and
gives those aggressive boy sperms a head start :-).
So, a shallow penetration will favor girls and a
deeper will favor boys. Shettles recommends
missionary-position for a girl, and rear-entry (dog-
style) for a boy.
The sperm count
The sperm count is another factor. Obviously, a
low sperm count to begin with doesn't favor either
sex. But a high sperm count favors boys. Shettles
recommends three things:
- When trying for a boy, the man should not
have an ejaculation for 3 days before reaching the
target date a day or two before ovulation.
(Intercourse earlier than 3 days before ovulation
should be with a condom only.) For girls, have sex
every day from the first day after your period ends,
and stop 3 days before ovulation. (No intercourse
even with a condom during that time.)
- Shettles recommends that for boys, the man
wear loose underwear only -- that is, men who usually
wear briefs or other tight underwear should switch to
boxers. The idea is the same as wearing boxers to
increase overall fertility -- the testicles need
cooler temperatures for sperms to survive, and the Y-
sperms, since they are weaker, will be helped more
than the X-sperms by this method. However, Shettles
does NOT recommend the opposite, that men wear briefs
for a girl -- this will just decrease overall
- Also, for a girl, the man is supposed to
take a hot bath immediately before intercourse.
'Room temperature' is fine for a boy. The idea is
the same as the briefs versus boxers -- give the X-
sperms an advantage.
In trying for a boy, Shettles recommends a nice
cup of caffeinated coffee for the man, right before
intercourse -- he isn't clear on how or why this
works, but apparently it gives the Y-sperms a jolt!
Concerning douching and the pH of the women's
reproductive tract: A more acidic environment favors
girls, since it will kill the weaker y-sperms first,
leaving a greater quantity of x-sperms available to
fertilize the egg. On the other hand, a more alkaline
environment favors boys. (Note: Some women are
naturally very acidic and have a hard time conceiving
Shettles *formerly* recommended two douching-methods
(involving vinegar or baking soda) to help alter
vaginal pH. However, in the most recent update (c.
1989) of his book, he no longer recommends douching
at all. His comment (pp. 179-180) is that one can
get equally-good results with or without the douches
Well, these are the big ones. Read the book for other
details. If you can determine the time of ovulation
and follow the rules presented in his book, Dr.
Shettles claims a success rate of 70-75% for girls
and 75-80% for boys (better than the 'normal' 50%).
As you see, it's not 100%!!!
Also, Shettles recommends a 'practice' period of 3-6
months, to make sure the couple has all the
techniques down properly.
A note about overall fertilty
Many of Shettles' methods are also valid (and
scientifically accepted) methods for increasing or
decreasing overall fertility. It's beyond the scope
of this FAQ to cover all aspects of fertility, but
paying attention to the following elements is
• A key to increasing fertility overall is
charting time of ovulation during every monthly
cycle. The three most common methods for determining
(1) charting basal body temperature (BBT);
(2) charting changes in cervical mucus; and/or
(3) using an ovulation test-kit.
•Regarding sex selection in particular, it is
beyond question that having sex very close to the
time of ovulation is an important way to increase the
overall odds for conception. Other methods that are
known to increase odds for conception include: deep
penetration at the time of ejaculation; for women,
having an orgasm together with or following the man's
orgasm; for men, wearing boxers instead of briefs;
and for men, avoiding hot baths or hot tubs.
•As you'll note, all of these also correspond
with methods that favor boys, according to Shettles.
In fact, he cautions that conceiving a girl may take
considerably longer than conceiving a boy, *and* may
take longer than conceiving using no techniques at
The Point: If you have trouble conceiving in
general, or think you might have such trouble, the
techniques for choosing a girl baby might not be for
you -- unless you're willing to be patient!

Well I am proof this method doesn't work. I tried this for each pregnancy and I now have 4 girls. I dont belive u can truely pick which sperm is gonna get there first it will always be a 50/50 chance imo. I would love a boy and md and hubby are ttc again but i will not be using this method again. If I get a boy so be it if not aslong as its healthy I don't care allynne7 (Jaime)

Hmmm, I'm curious to see if these methods work! I have both a girl and (soon-to-be-born) boy. Both were concieved the same way -me on bottom! But for my DD I hadn't gotten a period in 7 months when we found out we were 14 weeks pregnant. As for this little guy, we were using the pull and pray method, condoms, and not having sex the week of Ov. Somehow that didn't work out and this lil guy is due in 2 months! Okay, now I have to look up these methods! Lol! Lissie-McNamara;Mummyof1TTC

Hi Ladies, I would lilt to sway in an attempt to conceive a GIRL! I have 2 boys both of which were conceived while I was ovulating. Can those of you have that have been successful in your sway for a GIRL, please give me insight on the methods you used?

My question with this theory is this: if I O on CD15 and bd on CD9, 11, 13 and 12 hours before O - does that mean my chances are 50/50? Or because I had sex so close to O does it mean a boy or because i had so much sex leading up to O would it mean a girl...? It's all so confusing - I really don't mind what I have as long as it's healthy, just want to get that BFP, but thought I would ask for fun.. ;-) mommie-of-2

I think it's kind of a 50/50 shot no matter what. I really hope this method works and that I have followed it correctly. We will see I guess.
My poor daughter is surrounded by boys. Boys run in our family. All her cousins are boys, she has 2 brothers and all my friends have boys. When we have sleepovers, obviously we separate the girls and the boys and she can't figure out why she always has to sleep alone.
Seriously, my daughter was the last girl born into our family/circle of friends 6 yrs and 10 boys ago.
It is time for another girl. Babykhan

we are trying for a boy but I just read about how to do it to favor a boy. Well, I will be getting some ovulation tests and then we will try one day before ovulation. Let's hope it will work. A girl would be just as great. we have a girl and just want a little sibling for her. she is 5 months now.
