Resumen:
Introduction: One of the most intriguing
aspects of EDT is its association
with infertility when there is no mechanical
alteration of
the reproductive tract. Traditionally,
pregnancy has been considered
to be beneficial for patients with EDT leading
to the atrophy
of the endometritotic implants. However other
authors have reported
only symptomatic relief of the disease with
pregnancy. Objective:
Evaluate the effect of EDT on fertility in a
murine model of EDT.
Methodology: EDT was surgically induced in
female C57BL mice.
Four weeks after surgery animals were mated
until the presence of
vaginal plug. Animals were sacrificed on day
18 of pregnancy. After
sacrifice, EDT-like lesions were counted and
their size measured.
The number of pups, pups weight, and number of
implantation
sites were evaluated. Results: The time from
mating until the
presence of vaginal plug was similar between
animals with EDT
and sham animals. However, the pregnancy rate
in mice with EDT
was reduced. There were no significant
differences between animals
with EDT and sham animals in the number of
pups per mouse
and in the pups weight. There were no
significant differences in
the number of lesions per mouse in pregnant
compared to nonpregnant
mice. However, the lesions size was
significantly increased
in pregnant mice compared to non-pregnant
ones. Discussion: These
results suggest that EDT affects fertility in
mice and support the
use of this murine model to evaluate EDT
associated infertility.
