background: caffeine increases the camp production that stimulates spermatozoa movement. caffeine is also used for induction of in vitro acrosome reaction in mammalian spermatozoa, an important step in achieving fertilization. objective: the aim of this study was to assess the effect of caffeine on sperm's motility, vitality and laboratory fertilization rates in mouse in two t6 and m16 media. m...
Background: Normal growth of oocytes, embryos and also successful implantation depend on environmental factors such as the secretion of cumulus cells and composition of follicular and tubular fluids. Therefore, addition of serum, conditioned medium (CM) to the culture medium and also co-culture with somatic cells improve mammalian embryo development. So, in the respect to the secretion of diffe...
Introduction: Women with poorly controlled insulin-dependent diabetes mellitus (IDDM) have a much higher incidence of early pregnancy complications, these include spontaneous miscarriages, early growth delay, and congenital malformations. Most of the investigations have been devoted to the early post implantation and organogenesis period of pregnancy. In this research we studied the hyperglycem...
background: little is understood about the regulation of gene expression during early goat embryo development. this study investigated the expression profile of 19 genes, known to be critical for early embryo development in mouse and human, at five different stages of goat in vitro embryo development (oocyte, 8-16 cell, morula, day-7 blastocyst, and day 14 blastocyst). materials and methods: st...
