Suboptimal conditions of oocyte maturation and embryo culture in vitro reduce their developmental competence as compared to in vivo development. It is well known now that some IVF blastocysts, despite a proper morphology, are not able to hatch and implant after transfer. Therefore, it is suggested that during in vitro culture embryos show an ability to adjust to suboptimal conditions, which is however...
In this paper, the authors made an attempt to summarize the present knowledge on apoptosis in mammalian oocytes and embryos. On the contrary to necrosis, apoptosis is a programmed death of damaged or mutated cells. Several studies showed that it takes place during oogenesis (oocyte growth and maturation), as well as at some stages of preimplantation embryo development (morula, blastocyst). Although...
