Producing high-competent oocytes during the in vitro maturation (IVM) is considered a key
step for the success of the in vitro production (IVP) of embryos. One of the known disruptors …

In vitro maturation (IVM) is emerging as a popular technology at the forefront of fertility
treatment and preservation. However, standard in vitro culture (IVC) conditions usually …

Oocyte quality, which is directly related to reprogramming competence, is a major important
limiting factor in animal cloning efficiency. Compared with oocytes matured in vivo, in vitro …

Oxidative and nitrosative stress are common problems when handling gametes in vitro. In
vitro development in mammalian embryos is highly affected by culture conditions, especially …

The present study aimed to investigate the effect of melatonin (MT) supplementation on in
vitro maturation of vitrified mouse germinal vesicle (GV) oocytes. The fresh oocytes were …

The present study assessed the effects of supplementation of different antioxidants on
oocyte maturation, embryo production, reactive oxygen species (ROS) production and …

The efficiency of animal artificial breeding in vitro is still low. Oxidative damage is an
important obstacle for in vitro artificial breeding of animals. Melatonin can reduce the degree …

Poor‐quality oocytes (those with 1–2 layers of cumulus cells) typically possess low meiotic
competence and development. Prolonging the duration of in vitro maturation (IVM; 52 hr) …

Poor development of oocytes from prepubertal animals is a major factor that hinders the
application of the technology, juvenile in vitro embryo transfer (JIVET). The aim of this study …

The present study investigated the effects of melatonin on bovine oocyte maturation and
subsequent embryonic development in vitro. Results showed that the nuclear and …
