Insulin–transferrin–selenium (ITS) improves maturation of porcine oocytes in vitro

The objective of this study was to determine if insulin–transferrin–selenium (ITS) promoted a nuclear and cytoplasmic maturation of porcine oocytes that better supports subsequent embryonic development. The rate of oocyte in vitro maturation (IVM) in an experimental group treated with hormones for 42 h was significantly increased compared with that in a control group without hormone treatment (47.8% vs. 11.7%, respectively, p p p in vitro , and effectively enhances porcine oocyte nuclear and cytoplasmic maturation.
