Study: Gene may explain some cases of female infertility
ATLANTA (CNN) -- Findings in this week's journal Science may
shed light on some cases of infertility that doctors can't
now explain. In one-third of infertility cases, doctors are
not sure of the cause.
Dr. Jeffrey Milbrandt from Washington University School of
Medicine told CNN that a gene called NGFI-A may be
responsible for causing infertility in some women.
In studies with mice, Milbrandt found that the gene regulates
a hormone called LH (luteinizing hormone). LH causes women to
Milbrandt speculates that a lack of the gene or a mutated
gene could prevent ovulation. Although there are hormonal
treatments available to help some women ovulate, this finding
could spur more research into treatments.
