Comparative Aspects of Follicular Development, Follicular and Oocyte Maturation and Ovulation in Cattle and Pigs
The paper describes comperatively aspects of oogenesis and folliculogenesis, oocyte and follicular growth in cattle and pigs. Moreover, gonadotropin dependent regulatory processes of the wave like pattern of follicular growth are discussed in both species as well as functional and morphological changes during oocyte maturation. Finally, time dependent processes after oecurrence of spontaneous o...
متن کاملNovel signaling pathways that control ovarian follicular development, ovulation, and luteinization.
The interactions of peptide and steroid hormone signaling cascades in the ovary are critical for follicular growth, ovulation, and luteinization. Although the pituitary gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH) play key regulatory roles, their actions are also dependent on other peptide signaling pathways, including those stimulated by insulin-like growth fac...
متن کاملEvaluation of Texture Features for Analysis of Ovarian Follicular Development
We examined the echotexture in ultrasonographic images of the wall of dominant ovulatory follicles in women during natural menstrual cycles and dominant anovulatory follicles which developed in women using oral contraceptives (OC). Ovarian follicles in women are fluid-filled structures in the ovary that contain oocytes (eggs). Dominant follicles are physiologically selected for preferential dev...
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 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 ...
