Characteristics of
Mothers Study
What
is this study about?
You may have noticed in your daily
life that some families have all male or all female children. We are interested
in learning more about this phenomenon. Specifically, we would like to know
whether or not certain individuals might be more likely to have male or female
children, and what factors might influence this probability.
The purpose of this study is to
determine whether the levels of certain hormones that you were exposed to, both
prenatally (as you were developing in your motherŐs uterus) and throughout
adult life (that you produce naturally in your own body), is related to the sex
of a parentŐs offspring, their personality, and their cognitive ability.
Who
can participate?
We are currently looking for participants! If you, or someone you know, are
trying (or planning to try) to get pregnant in the next year, we need you!
Over the next year, we will be
recruiting as many women who are trying to conceive as possible.
In order to participate, you must
be:
á a
resident of Canada or the USA
á pre-menopausal
á currently
trying (or planning to try) to conceive (but not yet pregnant) with a known
partner or donor
á not using
any fertility drugs or other assistive technology to become pregnant
á not
taking any hormonal contraceptives or other hormonal medications
What
will I be asked to do?
This study is done ONLINE and will
only take about 1-2 hours to complete.
If you choose to participate in this
study, you will be asked to log on to our secure study website and complete a
variety of questionnaires and activities. You will also be asked to provide a
saliva sample (by mail), and to upload a scan of each of your hands and to
provide a photograph of yourself.
What
will my data be used for?
We will collect a saliva sample in
order to measure your levels of Estrogen and Testosterone at the time of our
study.
We will use your photographs in
other studies from our laboratory, where we will show them to other
participants and ask them in to make judgments about your physical and
reproductive attributes. Neither your name nor any additional personal
information will be associated with your photograph, or otherwise provided to anyone
in any of these experiments. Your photographs will NOT be published or
otherwise distributed to any third parties. You will be asked to sign a
separate release form providing consent for our use of these photographs.
We will take a hand scan so that we
can measure both the length of your index finger and your ring finger and
compare them. This will give us an idea of what your hormonal environment was
like prenatally.
**ALL SAMPLES AND INFORMATION COLLECTED WILL BE KEPT STRICTLY
CONFIDENTIAL AND USED ONLY FOR THE PURPOSE OF OUR STUDY.**
