We previously described a modern, three-dimensional counting method for determining primordial follicle (PF) numbers in primate ovaries using a combination of fractionator and physical dissector techniques. The purposes of our current study were 1) to apply our method to describe intraindividual differences in PF numbers between ovaries and 2) perform a linear regression analysis of age versus ...

This study was designed to investigate the effects of applying 1 mT static magnetic field (SMF) during the vitrification process, on the viability of ovarian follicles after vitrification-warming and autotransplantation. The study was conducted in two phases. In the first phase, ovaries of female NMRI mice (6 to 8 weeks old) were randomly divided into three groups: 1- Freshly isolated ovaries f...

BACKGROUND The purpose of this study was to assess the elastic properties of the carotid arteries in women with polycystic ovarian syndrome, asymptomatic women with polycystic ovaries, and healthy controls. METHODS AND RESULTS We recruited the following 60 subjects: 20 symptomatic women with polycystic ovaries attending the reproductive endocrinology clinics, 20 asymptomatic women with polycy...

For decades it was believed that a non-renewable pool of oocyte-containing follicles is established in female mammals at birth. This cornerstone of reproductive biology was challenged 5 years ago by a study reporting on the presence of mitotically-active germ cells in juvenile and adult mouse ovaries. Additional findings presented in this study and others that followed further suggested that ma...

The cortex-medulla growth pattern of oocytes in the developing ovary is formed by a rim of small non-growing oocytes at the periphery and growing oocytes at the inner part of the cortex and in the medulla. In this study we aimed to: (i) develop an in-vitro model using fetal mouse ovaries to evaluate when the cortex-medulla growth pattern is organized during ovarian differentiation; and (ii) stu...

This study describes the morphological and morphometrical changes associated with prepubertal ovarian development in the Antarctic minke whale (Balaenoptera bonaerensis). Ovaries were harvested from 94 immature minke whales caught in the Antarctic Ocean during the summer feeding season (December-March). Notable differences in ovarian size and morphology were found among animals. Up to 10 folds ...

Concentrations of cadmium, cobalt, cupper, iron, manganese and nickel were determined in four organs (liver, gills, ovaries muscles) Acanthopagrus latus, which belong to family Sparidae collected from Al- Razazah Lake. Heavy metals have been by means Atomic Absorption Spectrophotometry. The fish average weight was 378 g the length 215 mm. Iron showed highest value (1029.114 μg/g dry weight), wh...
