In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author's experience. In IVM cycles,...

Experiments were carried out to compare the sensitivity of Ancylostoma ceylanicum and Necator americanus to ivermectin (IVM) and pyrantel in vitro. Loss of motility and inhibition of ingestion by IVM were compared and A. ceylanicum was found to be approximately 40-50 times more sensitive to IVM than N. americanus. Both species showed a similar sensitivity to pyrantel. Uptake of [3H]IVM across t...

Background: Despite many variations made to the standard IVM protocol and to the culture conditions the rate of implantation ranges between 5% to 22% and the pregnancy rate ranges from around 8% to 40% [1]. The culture media is important as it provides the oocyte with vital metabolites such as ATP and pyruvate [2]. In order to improve the success rates with IVM, many changes have been made to t...

The fate of ivermectin (IVM) residues was studied throughout the processing of daily bulk milk from 30 ewes (taken up to 33 d following subcutaneous administration of 0.2 mg IVM/kg b.w.) in the following milk products: yoghurt made from raw and pasteurized milk; cheese after pressing; 30- and 60-day ripened cheese; and whey, secondary whey and whey proteins obtained after cheese-making (albumin...

OBJECTIVE The purpose of this study was to identify useful clinical factors for the identification of patients with polycystic ovary syndrome (PCOS) who would benefit from in vitro maturation (IVM) treatment without exhibiting compromised pregnancy outcomes. METHODS A retrospective cohort study was performed of 186 consecutive patients with PCOS who underwent human chorionic gonadotropin-prim...

The objective of this study was to evaluate the in vitro and in vivo developmental competence of parthenogenetic (parthenote) pig embryos derived from ovulated and in vitro matured (IVM) oocytes. A total of four experiments were carried out. These demonstrated that the mean blastocyst rates from stimulated ovulated and IVM pig oocytes were not significantly different (61% vs. 46%, p > 0.05) fol...

This paper focuses on modeling foreign exchange return behavior that would result in more accurate currency options pricing. These alternative approaches namely, implied volatility model (IVM), realized volatility model (RVM) and GARCH (1,1) volatility model (GVM) are used in this study. The results, in general suggest that RVM outperforms both IVM and GVM in pricing currency options. In-sample...

Widespread use of ivermectin (IVM) as part of the Onchocerciasis Control Program (OCP) in West Africa could influence the evolution of the human filarial parasite Onchocerca volvulus. Use of IVM, in some areas for 15 years, may have restricted genetic diversity of O. volvulus, resembling effects attributed to a population bottleneck. Large population-based chemotherapy programmes, such as the O...

In vitro maturation (IVM) of oocyte is an effective procedure for avoiding ovarian hyperstimulation syndrome in patients with polycystic ovaries (PCOS) during in vitro fertilization (IVF). To investigate the influences of IVM on epigenetic reprogramming and to search for the possible reasons for the lower rates of fertilization and cleavage in IVM oocytes, we examined the expression of two enzy...
