Cryopreservation of mature oocytes can result in damage to the metaphase spindle due to the temperature sensitivity of microfilaments and microtubules. Cryopreservation of immature oocytes may circumvent this problem because these structures have not formed yet and the genetic material is enclosed within a nuclear envelope. Because intact oocyte cumulus-oocyte ...

Self-control is a necessary component of subjective effort, but it depends only on farsighted motivation, with no additional, depletable resource. The aversiveness of boring tasks probably comes from their interference with endogenous reward, a new and potentially controversial concept. The self-control needed to stick with any kind of aversive experience ...
