Effects of media and the presence of bovine oviduct epithelial cells during in vitro fertilization on fertilizability and developmental capacity of bovine oocytes. Abstract Text:

Y H Choi,Y Fukui,H Ono,

The effect of the presence of bovine oviduct epithelial cells (BOEC; Experiment 1) as well as the effects of media (Tyrode fertilization medium: TFM vs synthetic oviduct fluid: SOF), fertilization containers (drops in petri dish vs 96-wells), and the number of oocytes per drop and well (5 vs 10) for in vitro fertilization (Experiment 2) on the fertilizability and in vitro development of bovine oocytes were investigated. Immature oocytes with cumulus cells were cultured in TCM199 supplemented with 10% ECS and 2.5x10(6) granulosa cells for 24 hours at 39 degrees C under 5% CO(2) in air. In vitro fertilization was performed with frozen-thawed, heparin-treated spermatozoa (100 mug/ml, 15 minutes) and with BOEC (Experiment 1). In Experiment 2, in vitro fertilization was performed with two different media (TFM and SOF) and various conditions (culture dish and different number of oocytes). Cleavage, development to the blastocyst stage were evaluated on Day 2 and Day 7 after the start of culture. Effect of the presence of BOEC on fertilizability and developmental capacity (Experiment 1) was not significantly different. In Experiment 2, alterations in media, containers and number of oocytes during in vitro fertilization had no affect. The SOF medium showed results similar to those of TFM (normal fertilization rate: 63.2 vs 64%; cleavage: 69.3 vs 73.9%; development to the blastocyst stage: 14 vs 15%; and mean number of nuclei per blastocyst: 80.5 vs 86.6). The results indicate that the presence of BOEC during in vitro fertilization did not improve fertilizability, and that SOF as well as TFM medium can be utilized as a simple fertilization medium.
