Developing oocytes arrest at the prophase of meiosis I, while the hormone progesterone restarts the process, leading to full maturation into a fertile egg. In this study we investigated the effects of hypergravity on this phase of maturation using oocytes of Xenopus. No differences were found between 2G, 5G and untreated controls regarding time to resumption of maturation, as judged by the appearance of a white spot in the animal hemisphere, whereas the white spot itself was larger and brighter in treated oocytes at time of appearance, and became even more pronounced as maturation proceeded. These findings suggest that although hypergravity does not affect the resumption of maturation, it might adversely affect the subsequent process and final results.
