Despite of being free from additional Cd exposure, the levels of CYP11A1 and CYP19A1 in the ovaries of F2 female rats were also high, which resulted in a high concentration of serum progesterone. These results suggested that hormonal changes induced by exposure to Cd in utero might have a...

We conducted studies in femaleProechimys(NOVX group) selecting the oestrus stage to minimise the bias related to hormonal changes. In our prev...
Daily fecal estrogen and progestin concentrations were measured by enzyme immunoassay in five female cheetahs (Acinonyx jubatus) for 4–6 months. The animals were housed under different conditions: (1) a female always housed in a group including one or more males; (2) two females isolated indivi...
Evaluation of the hormonal status of women by the use of vaginal smears remains one of the most practical, reliable, and economical tests available. Pouchet1 in 1847 was the first to correlate the cyclic changes in human and animal ovaries and the cyclic
Hormonal changes during pregnancy can affect the rate of OTM by influencing bone metabolism. Concurrently, the application of orthodontic force impacts hormone levels during pregnancy. OTM promotes estrogen expression in the serum and local periodontal tissue of non-pregnant female rats [149,150]. Alth...
Interestingly, however, female dispersal is also quite common among primates, with or without male philopatry (Lee and Strier, 2015; Moore and Ali, 1984). In several mammals, pubertal changes precede natal dispersal. For example, secondary sexual characteristics (specifically changing fur color) ...
