The present status of artificial oocyte activation in assisted reproductive technology
Reproductive Medicine and Biology, 2008 Intracytoplasmic sperm injection (ICSI) is the most effective treatment for achieving fertilization in assisted reproductive technology (ART). However, fertilization failure occurs. The incidence of fertilization failure after ICSI is 1–5%. Approximately 50% of fertilization failure cases could be attributed to the abnormality of sperm factor.

The MinK Potassium Channel Exists in Functional and Nonfunctional Forms When Expressed in the Plasma Membrane of \u3cem\u3eXenopus\u3c/em\u3e Oocytes [PDF]
, 1994 The minK protein induces a slowly activating voltage-dependent potassium current when expressed in Xenopus oocytes. In order to measure the levels of minK protein in the plasma membrane, we have modified the minK gene by inserting a 9 amino acid epitope ...

Effect of Ultrasound on Parthenogenic Activation of Mouse Oocyte [PDF]
Cell Journal, 2010 Objective: Artificial stimulation of mouse oocyte, in the absence of sperm contribution,can induce its parthenogenic activation of oocyte. Ultrasound is one of the newest methodsfor artificial activation of mammal oocytes, and its successful utilization ...

The effect of leukaemia inhibitory factor (LIF) on bovine embryo development in vitro : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]
, 1995 The aim of the study was to investigate the effect of Leukaemia Inhibitory Factor (LIF) either during in vitro maturation (IVM) or in vitro culture (IVC) on bovine embryo development. Three main experiments were conducted using oocytes aspirated from 2-8

Advanced Science, EarlyView.The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.
