Histological staging of ovaries was based on the stage of oocyte development and on the occurrence of postovulatory
follicles and atresia, described by Macchi et al.
Muscle bundles, thick ovarian wall and/or atretic oocyte or old, degenerating postovulatory
follicles might be present (Fig.

regression," Endocrinology, vol.
In females, ovaries were assessed and scored on a scale of 1 to 4, from minimum to maximum, for the following parameters: stroma size (mass of small follicles); follicle number; follicle size; amount of retained yolk material, indicating the presence of postovulatory
or atretic follicles; oviduct hypertrophy, indicating preparation for egg production; density of membranous covering of ovary; and flaccidity of the vent, also indicating preparation for egg laying.

progesterone concentrations in repeat breeder cows.
The histological observations of this study register for the first time the presence of hydrated oocyte phase in the mature ovaries and oocytes in atresia and postovulatory
follicle phase in the spent ovaries for H.
