Metabolites involved in cellular communication among human cumulus-oocyte-complex and sperm during in vitro fertilization
BACKGROUND Fertilization is a key physiological process for the preservation of the species. Consequently, different mechanisms affecting the sperm and the oocyte have been developed to ensure a successful fertilization. Thus, sperm acrosome reaction is necessary for the egg coat penetration and sperm-oolema fusion. Several molecules are able to induce the sperm acrosome reaction; however, this...
متن کاملEffect of Cumulus Oocyte Complex Morphology on in Vitro Maturation of Bovine Oocytes*
An experimental design was framed to analyse the effect of cumulus oocyte complex (COC) morphology on in vitro maturation of bovine oocytes. Slaughter house derived bovine ovaries from South Indian breeds and crossbred cattle of Kerala were subjected to three retrieval methods to yield different quality grades of oocytes. Based on the number of layers of cumulus cells and ooplasm character, the...
متن کاملO-11: Diverse Effects of Polyunsaturated Fatty Acids on Oocyte Maturation and Development In vitro
Background: Polyunsaturated fatty acids (PUFAs) have been shown to influence fertility and endocrinology of reproduction and metabolic activity in many species. In dairy cows, we and others have shown changes in steroid and metabolic hormones and prostaglandins leading to alteration of ovarian activity and uterine function. These can influence fertility by changes in folliculogenesis cyclicity ...
متن کاملEffects of dietary polyunsaturated fatty acids on ovarian function and prostaglandin secretion in lactating dairy cows
As lactating cows in severe negative energy balance have poor reproductive performance, the effect of dietary fat supplementation (fish oil, soybean oil) on PGFM secretion, ovarian function and blood metabolites is investigated. In this experiment, the effects of dietary polyunsaturated fatty acids on plasma metabolites, ovarian function and prostaglandin secretion of 20 primiparous Holstein co...
متن کاملAltered composition of the cumulus-oocyte complex matrix during in vitro maturation of oocytes.
BACKGROUND In vitro maturation (IVM) of mammalian oocytes has potential health benefits for patients undergoing assisted reproduction as an alternative to gonadotrophin treatment. This procedure is also useful for studying the process of oocyte and early embryo development. However, oocytes undergoing IVM have much lower competence than in vivo matured oocytes. Efforts to optimize IVM success h...
