Abstract

The aims of the present study are to investigate the histology of the different components of the foetal camel ovary, with special emphasis to the ovarian follicles and to determinate some histometric characteristics of the ovary during prenatal life. The present study was conducted in 79 foeti at different ages of development. The specimens were classified into first trimester (19 foeti), second trimester (26 foeti) and third trimester (34 foeti) according to the equation .The curved crown vertebral rump length (CVRL) equation Y= 0.366X-23.99 which was described by ELWishy et al., (1981) was used for the determination of the foetal age (X) in days from the known (Y) curved crown rump length in centimeters. Then the standard histological techniques were used to prepare the histological slides.  The primordial germ cells migrated through the mesentery and were found between the cells of the surface epithelium. The first primordial follicles appeared at (25 cm CVRL)   about (134 days old foetus) while at (28 cm CVRL) about (142 days old foetus) the first primary follicle was observed and at (65 cm CVRL) about (243 days old foetus) the first growing follicle was formed. The antral follicles were found only during the third trimester.
