Effects of in vitro cadmium exposure on ovarian steroidogenesis in rats
TLDR
Cd exposure appears to interfere with the ovarian steroidogenic pathway in rats at more than one site, with productions of P4 and testosterone in proestrus rats and less in pregnant dams, whereas E2 was not affected at all.
Effects of cadmium on serum sex hormone levels in pigs.
TLDR
The results showed that 10.0 mg/kg cadmium significantly decreased average daily gain, feed/gain ratio and Follicle-stimulating hormone, luteinizing hormone, oestradiol (E2) and progesterone levels in serum of the pigs fed the diet supplemented with 10.
Pubertal and postpubertal cadmium exposure differentially affects the hypothalamic-pituitary-testicular axis function in the rat.
Zinc protection against cadmium-induced infertility in female rats. Effect of zinc and cadmium on the progesterone production of cultured granulosa cells
TLDR
While Zn protected against Cd-induced sterility in vivo, it failed to counteract the direct effect of Cd on steroid biosynthesis and the data indicate that Zn protection does not take place at the level of ovary.
Effects of subchronic alternating cadmium exposure on dopamine turnover and plasma levels of prolactin, GH and ACTH
TLDR
It is suggested that cadmium exposure produces age dependent changes on the secretory mechanisms of the pituitary hormones studied, related to the selective accumulation of the metal at both hypothalamic and hypophyseal level changes.

Study of the luteinizing hormone-induced increase of ovarian blood flow during the estrous cycle in the rat.
TLDR
It was concluded that in LH-induced hyperemia, cAMP, prostaglandins and other vasoactive metabolites released during the process of hormone synthesis, and also a beta-adrenergic mechanism, are involved in the regulation of ovarian blood flow.
Effects of cadmium chloride on ovulation and on induction of sterility in the female golden hamster.
TLDR
The results indicate that CdCl2 inhibits ovulation when administered close to the time of ovulation, whereas its influence on pregnancy is pronounced but temporary.
Cyclic changes in utero-ovarian blood flow and ovarian hormone secretion in the hamster: effects of adrenocorticotropin, luteinizing hormone, and follicle-stimulating hormone.
These experiments were designed to determine utero-ovarian vein blood flow and ovarian secretion rates and the ability of ACTH, LH, or FSH to modify these parameters in the cyclic hamster. Hamsters
Peripheral levels of estrogen in the cyclic hamster.
TLDR
The day 4 peak in E2 was temporally related to the preovulatory surge in LH and an abrupt increase in ovarian progesterone, whereas the addition of 5 μg of LH restored E2 to normal values.

TLDR
Pregnant golden hamsters and mice of different gestational ages were injected intravenously with 109CdCl and cadmium administered on the 8th day accumulated in the primitive gut of the embryos, possibly disturbing the maternal-embryonic relationship and fetal nutrition.
Luteal blood flow and progesterone secretion in pseudopregnant rabbits.
TLDR
Ovarian and luteal blood flow rates were measured in anaesthetized rabbits on Day 8 of pseudopregnancy before and after lowering the ovarian perfusion pressure, indicating the presence of an autoregulatory mechanism in the ovarian interstitial gland.
