Clomiphene Citrate and Oocyte Quality
Ovary is a dynamic organ and generates excess amount of reactive oxygen species (ROS) during follicular growth, development, maturation and ovulation [1]. The increased level of ROS is scavenged by antioxidant systems [2]. A moderate increase of ROS could be beneficial for oocyte meiotic maturation and reproductive outcome [3-5]. Overproduction of ROS or depletion of enzymatic antioxidant syste...
متن کاملEvaluation of morphological criteria of sperm quality before in vitro fertilization and intracytoplasmic sperm injection.
The quality of sperm has a direct influence on the fertilization and developmental competence of embryos. In the literature we did not find defined criteria for evaluation of normal sperm parameters in various species of domestic mammals. Therefore we attempted to review evaluation of criteria of morphologically normal human sperm and their abnormalities. All sperm cells observed in the stained...
متن کاملQuality Criteria of Lenses
An ideal lens would be one which is able to produce an image which represents an object exactly. An ideal lens could transfer all of the details of the object to the image without any variations. An ideal lens, however, could only exist under ideal conditions, and in the real world ideal conditions can not be achieved. As such, we must deal with real lenses, and real lenses produce slight varia...
متن کاملWebsite Quality Assessment Criteria
The article presents a hierarchical framework, which supports website quality assessment. The framework is composed of a hierarchical structure of criteria and subcriteria and makes use of the Analytic Hierarchy Process to enhance criterion and subcriterion weight value assessment. To validate the framework we conducted an experiment, which involved the assessment of the websites of the three c...
متن کاملOocyte maturation and ovum quality in pigs.
Oocyte quality in pigs is defined as the potential of that oocyte to develop into a viable offspring. There is increasing evidence that the programming of the oocyte must be completed before leaving the ovarian follicle, including both nuclear and cytoplasmic maturation. Pig oocytes matured in vitro under basic conditions are deficient in some, as yet unidentified, cytoplasmic factors and thus ...
