This article is from the Choosing Your Baby's Sex FAQ, by Roger A. Hunt firstname.lastname@example.org with numerous contributions by others.
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
ovulation are: (1) charting basal body temperature
(BBT); (2) charting changes in cervical mucus; and/or
(3) using an ovulation test-kit. There are many good
resources for obtaining information on all these
methods, and on increasing fertility in general.
* 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!
[NOTE: I also compiled and maintain a FAQ on
low-tech ways to help you conceive -- i.e., what
you can do at home, before you seek medical
advice. It is posted monthly (in multiple
parts) on the same newsgroups as this FAQ, plus
alt.infertility and misc.health.infertility, and
is also available on the Web at
