Summary: To evaluate the effect of aspirin on infertile women with thin
endometrium, 114 women were placed into an aspirin group and 122 women into a
nonaspirin group. These subjects had an endometrium £ 8mm and intrauterine
insemination. Endometrial pattern and thickness, the pulsatility index and
resistance index of the uterine artery, spiral artery, and ovarian dominant
follicles, and pregnancy rates of both groups were measured. Significantly higher
percentages of trilaminar endometrium (46.5% vs. 26.2%) and pregnancy rate
(18.4% vs. 9.0%) after aspirin therapy were noted. Researchers concluded that
higher pregnancy rates and better endometrial pattern were achieved in patients
with thin endometrium after aspirin administration. However, aspirin therapy
could not significantly add to the endometrial thickness and the resistance of
uterine and ovarian flow.
Comment: Use of aspirin to improve implantation or prevent miscarriage has
been bantered about for a number of years. Theoretically, aspirin could improve
circulation by its action on prostacyclin/thromboxane pathways, but its
anti-inflammatory action could equally blunt the prerequisite inflammatory
response necessary for implantation. The mere fact that most do not use it can be
taken as an indication of its lack of effectiveness. I wish someone would perform
a definitive well-designed and controlled study to put this issue to rest.
