Histomorphological and histochemical studies on the female genitalia of aging goat. III. Polyovular follicles and polynuclear ova in ovary.
Polyovular follicles and polynuclear ova have been recorded to occur only in 5 goats out of 24 goats of ages between 2 months 24 days and 5 years 2 months 18 days, studied. These structures were recognized at proestrus, estrus and metestrus only but never in the animals over 1 year of age. Polyovular and polynuclear follicles with no apparent degenerative changes were seen at estrus whereas degenerating ones were commonly seen at proestrus and metestrus also.
