Background summary
Gender Consult in Waalre is a bureau which advises parents with natural
preconception methods which supposedly inlfuence the sex ratio in a substantial
manner.
These methods are based on a special preconceptional diet for the woman in
combination with a very precize timing of the intercourse. This study is
conducted to establish the scientific validity and effect of the methods used.
Gender Consult is prospectively providing information on the clients and the
outcome of the treatment is verified by University Maastricht.
Study objective
The primary objective is to establish whether the natural preconceptional sex
selection method (a diet in combination with a timing advise for intercourse),
as applied by Gender Consult, is effective.
Study design
The usual treatment of clients with Gender Consult consists of a diet to be
followed at least 10 weeks before conception, in combination with a timing
advice for intercourse. Usually, three blood samples will be taken to asses the
mineral content (Na+, K+, Mg2+, Ca2+). The studied cohorts consist of women
with a desire for a daughter that volunteer to participate in the research. All
participants agree to fill out a questionnaire at the end of the treatment and
to send in a birth announcement card when the treatment results in a baby.
The participants will be divided into two successive groups. The results of the
first group will be used to study the correlation between mineral blood values,
timing of intercourse, and the resulting gender. This will result in criteria
that have to be satisfied in order for the treatment to be deemed to be in
compliance with the advise. For the second cohort the sex ratio for
participants satisfying the afore-mentioned criteria will be compared with
usual sex ratio of untreated couples, in order to assess the effectiveness of
the method. Apart from the usual treatment by Gender Consult, this study will
consist merely in documenting the course and the outcome of the treatment.

Study burden and risks
The study is non-therapeutic, so the burden and the risks will be minimal. The
study will settle doubts and prejudices regarding the effectiveness of natural
gender preselection and will thereby provide a valuable scientific contribution
by quantification of the effects.
