Will 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
mark.
(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
the odds.)
Women's orgasms
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
fertility.
- 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.
Coffee
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!
Douching
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
boys.)
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
recommended earlier.
Book
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
certainly relevant:
• A key to increasing fertility overall is
charting time of ovulation during every monthly
cycle. The three most common methods for determining
ovulation are:
(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
all.
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!

Sorry this may be TMI but I read somewhere the way you have sex can determine the sex of your baby. I had a girl last time and having a boy this time. Both times tie in with what this article said, they said if you want a boy the female should orgasm first as it makes the vagina less alkaline meaning the male sperm can survive longer as they usually die off quicker then the females. sorry I know its TMI but when I've been asked by friends its the only thing we did different dandunam -

Called my insurance yesterday to find out i'm only granted ONE u/s this whole pregnancy. ;-( That's nothing. When I was pregnant with my kids abroad I had so many more. I was prepared to 'only' have 3 this time around, but what on earth am I going to do with ONE???!!! And we wanted to find out the gender.....what if baby doesn't show then??? I have two girls, would like a boy, but am happy to just have a third baby. dandunam -

Hey, I was wondering if the people who conceived a boy believe in the Shettles method? I am pregnant with a healthy baby girl. My husband and I would like one of each, so we want to try for a boy on the next pregnancy. mommyrock -

My husband and I were trying for a boy. We have a beautiful little girl but my husband wanted his boy. The chinese calendar said we were getting our boy, yipee! I had a threatened miscarriage at 15wks 6days and when we had the u/s to make sure the baby was still in there, we asked her to look over the area. There wasn't a turtle head. She was 90% sure we are having a girl. We will confirm it on the 21st. My husband and I don't care now about the boy, we weren't disappointed because we were so happy she was still in utero and heartbeat was a very healthy 152bpm. tripnstuff99 -

aejh...20 weeks is the norm. It has something to do with the babys development and the ability to see everything you want to see. I know...waiting sucks! I'm 17 weeks and have my ultrasound scheduled for the 11th of April. It seems so far away but hey...I'm having a great pregnancy and I keep telling myself not to rush it because it will be over before I know it. Good luck! Try to be patient...I KNOW its hard! aejh143 -

what's the soonest we can find out what we're having? I'm 15 weeks right now, and our scheduled date for the u/s is April 15th. If I don't have to wait that long I don't want to! Anyone know? AnOddBatch -

When I told my mom (who has three kids) that I was 11 weeks pregnant and that I'd had an u/s at 8.5 weeks her first response was, 'Really? So have you found out if it's a boy or a girl?' I was kind of stupified. Shouldn't my mom know that you can't tell that early? Weird. To be honest, my dad asked the same thing when I told him later that night...but I figured that was a little more understandable. kewald -

I have 2 girls already. On my last child (who is now 12 months old) we were told it was FOR SURE a boy up until the 18-19 week sonogram. We had to do fertility, so we had at least 7-9 sonograms before the 18-19 week one. All the different techs told us boy. Now I am pregnant with twins. Again, they said 2 boys FOR SURE until the 16 week one. Then at 16 weeks it was boy/girl twins. Then at 19 weeks we were told 2 girls! Since it is twins I get a sonogram every appointment and it is definately 2 girls. Be weary of those early sonograms!!!! I would say nothing is for sure until 18-19 weeks! M.M.Masi -

I would wait if I were you before buying anything blue. I also had my scan at 13wks 4 dys and was told that I was having 2 boys. They didn't look like your pic. I'm waiting for my next scan at 18 wks to be sure. crazylife85 -

Well, I had gone off the bc pill in June, started trying in august, got pg in Sept. I know the evening I conceived. I had sex about 3 days before ovulation, missionary position, I had no 'O', and laid in bed propped up for 30 mins. My hubby didn't know but I was trying for a girl...and I had my u/s jan 25th, it's a girl! :) I am thrilled. It worked for us!

For me,I think alot of the decision of baby's gender comes from the timing of intercourse..both my boys (19w preg and 3 1/2 yo) were concieved on THE DAY of Ovulation...I was tracking my cycles and both times I got pregnant was the exact day I ovulated...I guess if I want a girl I'll have to try to have sex a couple of days BEFORE ovulation.....lol

{Kristin1369} 'Happy New Year' Well, I had a gutt feeling that my baby was going to be a boy (picked out a name for him, i could even picture what he looked like) when everyone asked I told them undeniably it was a boy (that's how much I felt it) at my 20wk scan, found out it was a girl(they weren't 100% positive tho). I did cry for the loss of my baby-boy I was SO sure I was having...but I was just happy in the fact that she was happy & healthy. I asked again at a scan I had 2wks ago & the sonog said 'it's a girl!'. but just to be sure...i'm asking again in 5wks! lol

I hope I am right too. His Daddys says he'll be happy for a girl too but every man wants his little boy. He is really looking forward to teaching the baby to play sports. Hes a sports nut so probably he will teach all our kijds in the future but He hasnt had to much in his life to get exited about and I figured a little boy with his name would make him happy. That and he'll need somone to help him keep an eye on our girl when we have one lol. If we have a girl now shell never get out. He says she isnt dating until she is married haha. So I think we need a boy to distract him from that.
