Abstract
OBJECTIVE: To determine if extended treatment with doxycycline before and after an in vitro fertilization (IVF) procedure can minimize the detrimental effect of a hydrosalpinx. DESIGN: Retrospective analysis. SETTING: University IVF program. PATIENT(S): Patients undergoing IVF, including 17 with a hydrosalpinx, 25 with adhesions or proximal tubal occlusion, and 22 with endometriosis or unexplained infertility. INTERVENTION(S): Women with a documented hydrosalpinx were prescribed doxycycline 100 mg twice daily starting 1 week before expected retrieval and continued until 6 days after retrieval. No antibiotics were prescribed in the other groups. MAIN OUTCOME MEASURE(S): Implantation rates and IVF outcomes. RESULT(S): Implantation rates were 30% for the doxycycline-treated group of patients with a hydrosalpinx, 27% for the group with tubal occlusion/adhesion, and 24% for the group with endometriosis or unexplained infertility. Eight (47%) of 17 patients with a hydrosalpinx had a live birth, compared with 11 (44%) of 25 for the group with tubal occlusion/adhesion and 12 (55%) of 22 for the group with endometriosis/unexplained infertility. There were no differences between the groups in patient age, number of oocytes retrieved, fertilization rate, or number of blastomeres of the transferred embryos. CONCLUSION(S): No detrimental effect of a hydrosalpinx was evident for patients treated with extended doxycycline. Tremendous cost savings can be realized if treatment with 2 weeks of an inexpensive antibiotic provides outcomes comparable to surgical correction of a hydrosalpinx before IVF.
