The team wanted to know why females are indifferent to males during the infertile period known as diestrus.
Among animals with irregular cycles, extended/abnormal diestrus was observed in two control littermates, two females (non-littermates) at 500x, five females (four litters) at 1,000x, and three females (three litters) at 2,000x.
High doses of Anethum graveolens seed aqueous and ethanol extracts caused significant increase in duration of the estrous cycle, diestrus phase and progesterone concentration (8, 9).
At a lower dose (50 mg/kg BW), the extract produced an anti-oestrogenic effect, inhibiting implantation with cessation of the oestrous cycle and continuous diestrus, suggesting secretion of oestrogen from the ovary was not occurring.
Diestrus was identified by predominance of small cells (leukocytes) as well as larger, round, nucleated epithelial cells and cornified epithelial cells; diestrus II by leukocytes and round, nucleated epithelial cells with few cornified epithelial cells; proestrus by round, nucleated epithelial cells; and estrus by cornified epithelial cells.

The aim of the present work was to provide the literature with helpful considerations regarding the distribution of cornified cell determinations during proestrus, estrus, metestrus and diestrus in rats receiving estrogen.
