Abstract
The rat oocytes extracted from the rat ovaries and cultivated for 42-46 hours were compared with ovulated oocytes by the chromosomal aberration rate. The chromosomal aberration rate in the population of "follicular" oocytes was 8.2% on the average whereas in ovulated oocytes, it did not exceed 1.8%. Analysis of the chromosomal aberrations depending on the phase of the estral cycle suggests that the main portion of chromosomal aberrations in cultivated oocytes occurs during the physiological process of follicular atresia.Preview Only.
