Repeat transvaginal ultrasound-guided aspiration of ovarian endometrioma in infertile women with endometriosis.

Objective: We sought to investigate the effectiveness of repeated transvaginal ultrasound-guided aspiration of endometriomas in infertile women with endometriosis.
Study Design: A retrospective study was performed in our department of reproductive health on 129 infertile women who underwent monthly repeated transvaginal aspiration of endometriomas. The recurrence and pregnancy were monitored during a follow-up period of 24 months.
Results: Recurrences of cysts were found in 118 (91.5%) patients in the first postaspirate month and 86 (66.7%) in the second, 60 (46.5%) in the third, 28 (21.7%) in the fourth, 12 (9.3%) in the fifth, 7 (5.4%) in the sixth, and 36 (27.9%) in the 24th postaspiration month. Mean 3.1 ± 2.8 times of aspirations per patient were performed without any adverse effect. There was a linear regression relationship between the change of times of aspirations and the chance of recurrence of cysts. Overall pregnancy rate of 43.4% (56/129) was obtained.
Conclusion: The repetitive aspiration of endometriomas is an effective therapeutic option in patients with endometriosis.
