ABSTRACT
OBJECTIVE: This report presents a summary of the outcomes achieved at ART center FERTILAB in Buenos Aires, Argentina, with transport IVF-ICSI for 25 years (1990-2014). METHODS: This report included all patients submitted to oocyte retrieval for IVF-ICSI whose oocytes were transported from sites of aspiration located 0.5-58 kilometers away from the central laboratory. The numeric data herein reported were taken from annual reports submitted by our institution (Fertilab) and, for purposes of comparison, by all Argentinian centers to the Latin American Registry of Assisted Reproduction (RLA) within the same time period. RESULTS: From 1990 to 2014, 5091 aspirations followed by oocyte transport were performed in our center, resulting in 1258 pregnancies after fresh embryo transfers. The mean pregnancy/aspiration rate for the 25-year period was 24.71%. To validate the efficacy of our transport system, our results were compared to the outcomes of Argentinian centers reporting to RLA Argentina in the period ranging from 1990 to 2014. A total of 79,062 aspirations were performed, yielding 20,047 pregnancies and a pregnancy/aspiration rate of 25.36%. Delivery/aspirations rates were 15.34% for Fertilab patients and 14.79% for RLA Argentina centers. CONCLUSION: The results showed that the differences in clinical outcomes between our center and the bulk of Argentinian centers were not statistically significant, indicating that oocyte transport does not decrease the effectiveness of IVF-ICSI and might be advantageous under certain circumstances.

OBJECTIVE: To confirm the beneficial effect of endometrial coculture in patients with repeated failures with assisted reproductive techniques (ART). DESIGN: Patients with previous failures were offered a repetition of ART in conjunction with autologous endometrial coculture. SETTING: Private fertility center. PATIENT(S): Sixty-eight couples who had attempted 92 cycles of IVF or intracytoplasmic sperm injection without obtaining an evolutive pregnancy. INTERVENTION(S): Patients repeated one cycle of ART with concomitant endometrial coculture of their embryos. MAIN OUTCOME MEASURES(S): Comparative pregnancy and delivery rates in conventional ART cycles vs. cycles with autologous endometrial coculture. RESULT(S): In the previous 92 cycles (146 ETs, fresh plus frozen) only 8 pregnancies were initiated, and all ended in spontaneous abortion. Upon repeating 68 cycles (76 ETs) using coculture, 39 pregnancies were obtained, of which 19 resulted in live births, 10 are ongoing evolutive pregnancies, and 10 ended in spontaneous abortions. CONCLUSION(S): These results confirm the usefulness of autologous endometrial coculture for the treatment of patients with repeated implantation failure.
