RESUMEN
STUDY OBJECTIVE: To evaluate the efficacy of laparoscopic surgery in a series of women with hydrosalpinx. DESIGN: Prospective, observational study (Canadian Task Force classification II-2). Setting. University-affiliated hospital. PATIENTS: Sixty-one women undergoing bilateral neosalpingostomy and restoration of tubal ovarian anatomy laparoscopically, and followed for 24 months. INTERVENTION: Video-controlled operative laparoscopy using standard four-puncture technique. MEASUREMENTS AND MAIN RESULTS: During 24-month follow-up, cumulative intrauterine pregnancy rates at 6-month intervals were 6.8%, 13.6%, 20.5%, and 20.5% for patients with only distal tubal obstruction and 12%, 23%, 29%, and 29% for those with mild degree of tubal disease and periadnexal adhesions. Miscarriage rate for intrauterine pregnancies was zero in both groups. CONCLUSION: Operative laparoscopy seems to be an effective treatment for hydrosalpinx in terms of pregnancy outcome.

PURPOSE: This study deals with the suitability of Ham's F-10 without hypoxanthine for early cleavage-stage embryo culture. A high percentage of mouse two-cell embryos developed into morula and blastocysts in Ham's F-10 formulated without hypoxanthine (75.3 and 71.6%, respectively); in contrast, in agreement with previous reports, only 15.4% developed beyond the two-cell stage in Ham's F-10 with hypoxanthine. To begin to evaluate the effect of hypoxanthine on human embryos, a total of 318 human oocytes was fertilized and cultured in Ham's F-10 minus hypoxanthine. RESULTS: The fertilization, cleavage, and pregnancy percentages in two ovulation induction protocols [human menopausal gonadotropin (hMG)/human chorionic gonadotropin (hCG) and gonadotropin releasing hormone/hMG/hCG] were 82, 88, and 20 and 83, 91, and 30%, respectively. CONCLUSION: These results suggest that, in agreement with mouse embryo development, hypoxanthine does not appear to be necessary for human embryo cleavage and its omission from Ham's F-10 may enhance the conditions for culture of early-cleaving human embryos. These observations may lead to a better understanding of critical cell processes during early human embryonic development.
