The 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 کاملThe distribution of corpora lutea and ovarian follicular development in pregnant goats.
The main objective of the study was to determine the number of growing follicles (diameter>or=4 mm) with regards to the distribution of corpora lutea (CL) on the ovaries in pregnant goats. Growing follicles with a diameter greater than 5 mm i.e. large follicles were also recorded and analyzed. Daily ultrasonography (USG) examinations of ovaries were made in six Polish White Goats starting from ...
متن کاملThe 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 کاملThe mammalian oocyte orchestrates the rate of ovarian follicular development.
The development of both the mammalian oocyte and the somatic cell compartments of the ovarian follicle is highly coordinated; this coordination ensures that the ovulated oocyte is ready to undergo fertilization and subsequent embryogenesis. Disruption of this synchrony results in oocyte developmental failure. Communication between the oocyte and companion somatic cells is essential for successf...
متن کاملSeasonal effects on ovarian follicular development in pony mares.
To define ovarian follicular kinetics in the equine ovary during anestrus and the breeding season, the follicular population of pony mares was investigated at mid-anestrus and at the beginning and end of the breeding season. There was a clear effect of season on the exit of reserve (primordial and initiated) follicles since at the beginning of the breeding season we noticed a higher mitotic ind...
