introduction: superovulation produces complications in some patients, so invitro maturation of oocytes is used to decrease or eliminate these complications and improve ivf. moreover, ivm is used for different aspects of reproductive researches. slaughterhouse ovaries are the main source of oocytes for ivm and ivf studies. different media has been introduced and experimented for in vitro maturat...

Role of the bed nucleus of stria terminalis (BST) in the control of gonadotropin release in the female rat was studied. Electrical stimulation of the BST on the day of diestrus II increased the serum concentration of FSH, but not of LH. The stimulation on the day of estrus increased serum concentration of LH as well as on the day of proestrus. In the ovariectomized and estrogen-treated rat, the...

To investigate uterine and serum Ca++ and Mg++ variations during the estrous cycle in the bovine, 66 genital tracts and blood samples were collected from Urmia abattoir, Urmia, Iran. The phase of the estrous cycle was determined by examination of the structures present on ovaries and uterine tonicity. Of the collected samples, 17 were pro-estrus, 12 estrus, 14 metestrus and 23 diestrus. The ute...

to investigate uterine fluid and serum calcium (ca) and magnesium (mg) variations during the estrus cycle in water buffaloes, 71 genital tracts and blood samples were collected from the abattoir in urmia. the phase of the estrous cycle was determined by examining ovarian structures. 18 animals were pro-estrous, 15 estrous, 16 met-estrous and 22 diestrous. the uterine fluid was collected by gent...

OBJECTIVE In this study, we examined changes in serum leptin levels during the estrus cycle and the role of estrogen in these changes. METHODS We measured serum leptin levels during normal estrus cycles in intact rats and estradiol-17beta (E2)-induced artificial estrus cycles in ovariectomized rats. RESULTS Serum leptin levels increased 1.6-fold from 4.2 +/- 0.2 ng/ml during diestrus stage ...

To investigate uterine and serum copper (Cu) and zinc (Zn) concentrations variation during the bovine estrus cycle , 232 blood and genital tract samples were collected from the abattoir in Urmia. The phase of the estrous cycle was determined by the examination of the ovaries and the uterine tonicity. Of the 46 samples selected for use in the study, 13 were pro-estrus, 10 estrus, 8 metestrus, an...

To investigate the IgG content and its variations in uterine fluid (UF) during the estrous cycle of the cow and to compare them with those of the blood serum (S), six pairs of serum and UF samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from Urmia abattoir. The UF samples were collected by gentle scraping of the endometrium using a ...
