...cholesterol, progestril, estradiol, and androgens were estimated at the end of the experiment. The ovaries of the rats were collected, weighed and histopathologically evaluated for the development of cysts. It was seen that the ovaries of the group treated with caged chicken meat showed increased cholesterol levels, imbalanced steroidal sex hormone levels, increased ovary weight and development of the cysts upon histopathological examination as compared to the...

GSI increased during March concomitant with gradual increase in levels of T, P and 17α-HP. Highest values of these parameters were observed at different stages of gonadal development. T and 11-KT played key role in progress of testicular developmen...

After the recovery period, EROD, GST, malondialdehyde, estradiol/testosterone levels were found to be lower than the control. In the pesticide mixture group, the...

However, estradiol (E2)in rats treated with 50 µg/kg cabergoline was higher than that in control group at day 24, and progesterone (P) secretion was not remarkably influenced by cabergoline. Moreover, the duration of investigation toward normal females in the 50 µg/kg groups at day 3 exceeded that of pre-treatment. The females treated by 100µg/kg cabergoline increased the frequency of investigation towards normal fe...

... Plasma progesterone and estradiol-17β concentrations were determined throughout the cycle using radioimmunoassay. The average length of the estrous cycle in Lohi sheep was 17.0±0.1 days and follicular and luteal phases were 4.6±0.2 and 11.3±0.2 days long, respectively. Estrous cycles had either three or four follicular waves; 3-wave cycles were more frequent than 4-waves (87vs.13%; p≤0.05, respectively). In 3-wave cycles (n...

Testicular morphometry, scrotal circumference, Doppler examinations, image analysis, and blood sampling were performed on a weekly basis. Results showed that FSH level was e...

A total of 44 female Marecha camels were selected in Thal desert of Pakistan during breeding season (December-March) and kept under semi-intensive management system (SIMS). Selected animals were divided into two comparable groups of 22 animals in each to determine the hormonal profile. G1 was composed on lactating non-pregnant while G2 had newly bred she camels.

Blood samples for serum were collected for oestradiol and luteinizing hormones. Follicular diameters at 42 hr were longer (P<0.05) in hot dry season (8.088±0.52 mm) than in raining seasons (8.618±0.9 mm) and cold dry season (6.338± 0.68 mm). At 72 hr follicular diameters were longe...

It increased the total cholesterol in males only and elevated the triacylglycerols and glucose levels in both sexes. The administration of testosterone to males, females, or both reduced the fertility index to zero. The mating success was also reduced from 80 to zero when both the males and females were administered with testosterone. The synthetic testosterone ...

.... Blood progesterone and estradiol revealed distinct but synchronized patterns in both groups. Group 2 displayed a consistent decline in blood progesterone from day 0 to 7, and a spike on days 7-11, attributed to the second prostaglandin analogue administration. The subsequent decline on days 12-13 signalled impending estrus, accompanied by a rise in blood estradiol. Group 3 exhibited a progesterone spike on day 10, with a c...
