the influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Glycomic analyses of ovarian follicles during development and atresia
To examine the detailed composition of glycosaminoglycans during bovine ovarian follicular development and atresia, the specialized stromal theca layers were separated from the stratified epithelial granulosa cells of healthy (n=6) and atretic (n=6) follicles in each of three size ranges: small (3-5mm), medium (6-9mm) and large (10mm or more) (n=29 animals). Fluorophore-assisted carbohydrate el...
متن کاملEstradiol, progesterone, testosterone profiles in human follicular fluid and cultured granulosa cells from luteinized pre-ovulatory follicles
BACKGROUND The production of sex steroids by follicular cells is proposed to be influenced by the maturity of the incumbent oocyte. Thus steroid levels may reflect suitability of an oocyte for IVF. We examined follicular fluids and granulosa cell production of steroid from IVF patients in order to test the relationship between steroid levels and fertilization. METHODS Follicular fluid and gra...
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 کاملApoptosis and Ovarian Follicular Atresia in Mammals
The reproductive performance of any mammalian species can be enhanced by enriching nutrition, regulating environmental factors like photoperiod, temperature, humidity etc., through selective breeding, endocrine manipulations and better management practices (Sharma, 2000; Maillet et al., 2002; Bussiere et al., 2002; Iwata et al., 2004, 2005; Rudolf, 2007; Bhardwaj and Sharma, 2011). The endocrin...
