Examples of corpora lutea

• Pre-implantation loss was determined by comparing the number of implantation sites with the respective number of corpora lutea.

• The embryo recovery rate from the four females was 87.9% of the total number of corpora lutea.

• This model was selected for study over the mature rat ovary which contains simultaneously developing follicles, ovulatory follicles, and corpora lutea.

• Positive correlated responses were found for number of corpora lutea and number of live fetuses.

• The stage of the estrous cycle was defined by careful examination of the ovaries (follicles and corpora lutea).

• The corpora lutea were visualized with the aid of a low-power dissecting microscope.

• Total corpora lutea were also analysed with the covariate 10-week body weight included in the model.

• Adjusting corpora lutea number for body weight reduced the correlated response but did not eliminate it.
