The Effect of Ligation of the Ovarian Artery on Ovarian Follicular Function in Rats
In the present study was performed to evaluate the follicular growth and hormonal changes after ovarian artery ligation in rats. Fifty six virgin 90-day–old female rats were used. The rats were chosen from 100 female rats by a vaginal smear, which showed that they were synchronized in estrous phase of the menstrual cycle. Animals were kept in seven cages (n=8 in each) at a temperature of 22 ± 2...
متن کاملProgress in understanding ovarian follicular dynamics in cattle.
The study of follicular dynamics began in the mid-20th century, but progress has been particularly rapid in the last two decades through the use of tools that have enabled serial, non-invasive examination. A brief overview of early oogenesis and folliculogenesis is provided as a backdrop to the evolution of our understanding of follicular dynamics during the bovine estrous cycle. Studies to dat...
متن کاملThe Effect of Vitrification on Follicular Morphology of Ovarian Rat
Background & Objective: Some efforts have been made for keeping cryopreservation of gametes and embryos safe, including new vitrification methods of the ovary. This study evaluates the effect of ethylene glycole vitrification on follicular morphology of ovarian rat. Materials & Methods: Eighty ovaries belonging to 40 rats are divided into 2 groups. Twenty five ovaries are control group, 25 the ...
متن کاملOvarian Follicular Atresia
Throughout ovarian development and function in mammals, a highly orchestrated, periodic process known as follicular atresia occurs that destroys and eliminates follicles and oocytes from the ovary. Follicular atresia is pervasive. In humans, it is estimated to account for 99.9% of the loss of oocytes from development of the fetal ovary until reproductive senescence (Baker, 1963; Faddy et al., 1...
متن کاملOvarian Follicular Dynamics during the Estrous Cycle in Jennies in Upper Egypt
The objective of the current study was to describe follicular dynamics in Egyptian Jennies throughout the estrous cycle. In this experiment, 8 estrus cycles in 8 cyclic Jennies were studied from February to June using ultrasonography. The result revealed that one follicular wave per cycle was recorded throughout the studied period. Dominant follicle (DF) was firstly detected at -0.80 ± 0.84 day...
