Abstract
Genitalia includingovaries of slaughtered female camels at different stages of pregnancy were collected from slaughterhouses. They were examined to studying the morphological and histological changes of the ovary during different stages of pregnancy, early (1-3 mo), middle (4-8 mo) and late (9-12 mo).
Results revealed that average weight of the ovaries with corpora lutea (CLa) and of, the same ovaries without CLa did not differ significantly during the early (8.17 and 4.41 g) and middle stage (8.33 and 4.29 g). However, they significantly increased during the late stages of pregnancy (9.69 and 4.61 g). Weight and length of corpus luteum (CL) significantly increased only between the middle and late stages of pregnancy by about 7.4 and 3.7%, respectively, while diameter of CL significantly increased between the middle and late stage. Corpora lutea were located in the right ovaries in 43.3%, in the left ones in 50.0% and in both ovaries in 6.7% of all pregnancies. All embryos or foetuses were observed in the left uterine horns and frequent of ova or embryos migration from the right to the left side was 46.4%. Most of ovulation occurred in a single type in 86.7%, double type in 10.0% and triple in 3.3% of all pregnancies.
The histological examination of CL revealed that early signs of regression appeared at the end of the early stage of pregnancy (the 4th mo). This may indicate that the process of regression was slow and gradual without any changes in CL mass and somewhat changes in its shape.
