“…PREVIOUS TRANSPORT ART studies have already indicated no differences in rates of fertilization, cleavage, transfer or pregnancy with conventional IVF and ICSI using the transport oocyte method and performed entirely at the ART center. Delay as a result of transportation in commencement of culture does not reduce the pregnancy rate, reduce the ability during ICSI of the oocyte to endure sperm injection, or subsequent embryo development and ability to implant 7–16 . We have also achieved favorable results with our round trip method, where transported fresh embryos are implanted at satellite clinics 6,17,18 .…”

Background and Aims:We evaluated the efficacy of the transport oocyte/embryo frozen/thawed embryo transfer method, in which oocytes or embryos were transported from satellite clinics to the main assisted reproductive technology (ART) center, and surplus embryos were placed in cryopreservation. Methods:We evaluated 41 cycles in 34 patients in the transport oocyte group (TO group). In the TO group the oocytes were collected at the satellite clinics, transported to the main ART center and underwent in vitro fertilization or intracytoplasmic sperm injection. Surplus embryos were used for frozen/thawed embryo transfer. We also evaluated 17 cycles in 10 patients in the transport embryo group (TE group), where surplus embryos were transported to the main ART center and used for frozen/thawed embryo transfer; and 189 cycles in 134 patients in the center group (C group), where surplus embryos collected at the same time at the main ART center were used for frozen/thawed embryo transfer. Oocytes were transported from satellite clinics in HEPES buffered human tubal fluid (HTF) culture medium, and embryos in 30% synthetic serum substitute + HEPES buffered HTF, using a portable incubator we devised. Results:The proportions of undamaged embryos after freeze/ thawing were 47% for the C group, 46% for the TO group, and 46% for the TE group. The numbers of embryos transferred were 2.0 ± 0.7 for the C group, 2.0 ± 0.6 for the TO group, and 2.2 ± 0.4 for the TE group. The rate of embryo transfer was 63% for the C group, 68% for the TO group, and 76% for the TE group. Pregnancy rates per patient were 16% for the C group, 24% for the TO group, and 40% for the TE group. The embryo survival rates (number of embryos with ≥50% viable blastomeres/total number of embryos) were 55% for the C group, 60% for the TO group, and 54% for the TE group. No significant differences were seen between the C group and either the TO or TE groups in any of these parameters. Conclusions:

ObjectiveThis 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).MethodsThis 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.ResultsFrom 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.ConclusionThe 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.

“…P REVIOUS REPORTS OF transport assisted reproductive technology (ART) suggest that transportation per se does not adversely affect the oocytes. [1][2][3][4][5][6][7][8] During the past 6 years, we have used transport ART in more than 250 patients, collecting oocytes from more than 350 cycles. Our transport ART network comprises the center facility (at the Department of Obstetrics and Gynecology, Omori Hospital attached to the Toho University School of Medicine, Tokyo, Japan) and satellites, including three facilities that use the round-trip method in which oocytes and embryos are transported between the main ART center and the satellite facilities, 9,10 11 facilities that use the one-way method for oocytes, one facility that transports embryos to the center for cryopreservation, 11 and three facilities where the ART treatment modality is selected on an individual basis ( Fig.…”

In transport assisted reproductive technology (ART), the time taken to transport oocytes to the main center differs greatly among the satellite facilities and may influence the clinical results. For the conventional fertilization (IVF) groups in which oocytes were collected at the satellite facilities and transported to the main ART center for insemination and embryo transfer, there were 29 cycles in 27 patients with a transportation time within 60 min (short time transport IVF (ST-IVF)), 78 cycles in 62 patients with a time between 60 and 120 min (long time transport IVF (LT-IVF)), and there were 141 cycles in 110 patients at the main ART center (center IVF (C-IVF)). For the intracytoplasmic sperm injection (ICSI) group, there were 65 ST-ICSI cycles in 42 patients, 146 LT-ICSI cycles in 97 patients, and 326 cycles in 238 patients at the main ART center (C-ICSI). The morphologically favorable embryo rate was lower in the ST-ICSI group (33.8%, < 0.05) than in the C-ICSI group (38.1%), and the morphologically poor embryo rate in the LT-IVF group (38.6%, < 0.0001) was higher than in the C-IVF group (26.7%). The rate of embryo transfers resulting in pregnancies was 16.7% in the ST-ICSI group ( < 0.01) and 17.3% in the LT-ICSI group ( < 0.001), both less than that of 35.2% for the C-ICSI group. To improve both the morphologically favorable embryo rate and the pregnancy rate in transport ART, it is essential to improve the total quality control at the satellite facilities.
