Possible Interaction: Progesterone and Selenium

“Form of Se tended to affect (P = 0.07) the concentration of progesterone , but not that of estradiol, in the follicular fluid.”

“Our results suggest that form of Se fed to cows affects the production of progesterone but not that of estradiol.”

“ Se supplementation did not affect the length of the estrous cycle, but it did increase the concentration of plasma progesterone in the estrous cycle (P<0.001).”

“ Se addition from 5 to 200 ppb elevated progesterone concentration of the culture medium in a dose-dependent manner which was associated with an increase in cell proliferation rather than an increase in progesterone production per cell, and decreased the lipid peroxide content of luteal cells.”

“The uterine extraction of progesterone was significantly (P = 0.001–0.005) higher in the early follicular phase [37.0 ± 7.8% ( SE )] than in the luteal ph...”

“We have reported that the form of supplemental Se provided to Angus-cross beef cows can affect circulating levels of progesterone (P4) on day 6 of the estrous cycle, a time when increased P4 is known to promote fertility.”
