Embryonic loss, measured by the difference in mean number of corpora lutea
and mean number of fetuses, was 32.
The effect of Regu-Mate, a synthetic progestin, on early pregnancy maintenance, conceptus growth, and corpora lutea
development in pregnant pony mares.
However, we found evidence of reproduction in the form of corpora lutea
, blastocysts, embryos or placental scars in 35.
In New Hampshire, age, antler spread, antler beam diameter (ABD), number of points, corpora lutea
(CL) count, and field-dressed body weight of hunter-harvested moose have been measured since 1988.
In this experiment superovulatory response was evaluated by number of corpora lutea
formed on Day 7 after the oestrus, using real time, transrectal ultrasonography.
It is interesting to note that both the number of implantation sites and corpora lutea
decreased in the alkaloid-treated animals when the process of implantation ought to have been completed (implantation takes place normally within 5-6 days post-coitus in rats) before the exposure of the animals to the alkaloid mixture (treatment commenced from day 10 of pregnancy).
Levels of messenger ribonucleic acid encoding cholesterol side-chain cleavage cytochrome P-450, 17 alpha-hydroxylase cytochrome P-450, adrenodoxin, and low density lipoprotein receptor in bovine follicles and corpora lutea
throughout the ovarian cycle.
The histological analysis of ovaries showed the presence of newly formed corpora lutea
or Graafian follicles in all the treated rats indicating that these rats were in estrous or in proestrous phases of the estrous cycle, respectively.
Whereas the Poisson probability distribution function analyzed the number of corpora lutea
in the ovaries (right and left), total structures, unfertilized structures, degenerate and congealable embryos, the logarithmic function of connection was estimated by the generalized linear model methodology (NELDER; WEDDERBURN, 1972) using GLIM 4.
The relative development of the corpora lutea
and corpora atretica and their function remains unknown (Dodd 1983).
Control of corpus luteum function in the pregnant rabbit: role of the placenta ("placental luteotropin") in regulating responsiveness of corpora lutea
