Benefit of in vitro fertilization treatment for endometriosis-associated infertility.
OBJECTIVE
To evaluate the effectiveness of IVF treatment in endometriosis-associated infertility.


METHODS
Nonrandom retrospective study.


METHODS
Department of Gynecology and Obstetrics, Akita University School of Medicine.


METHODS
Cumulative pregnancy rate.


METHODS
One hundred eighteen infertile patients in whom diagnosis of endometriosis was established by laparoscopic examination.


METHODS
The prognoses of 60 patients (IVF group) who started IVF treatment within 6 months after laparoscopy were compared with those of 58 patients who were managed expectantly without IVF treatment during the same period.


RESULTS
The cumulative conception rates at 36 months after laparoscopy were 62% in the IVF group and 43% in the control group, and the difference was not significant (a log-rank test). For patients > or = 32 years of age, the conception rates were significantly higher in the IVF group (59% versus 29%). A relatively large but nonsignificant difference in the conception rate between the two groups was observed in patients with endometriosis at stages III or IV (52% versus 27%).


CONCLUSIONS
In vitro fertilization treatment provides better prognosis in patients > or = 32 years of age and is recommended for such patients. The benefits of treatment appear to be greater in patients with more advanced stages of endometriosis.
