Abstract

Hypophysectomized, adult Anolis carolinensis were treated with daily injections of either saline alone or with 1, 10, 50, or 100 μg of ovine follicle-stimulating hormone (FSH) for 7 or 14 days. Stimulatory effects of FSH were observed on ovarian and oviductal weights and number of oogonia, naked primary oocytes, primordial follicles and growing follicles. FSH also influenced the patterns of follicular yolking and atresia and the intraand interovarian follicular size hierarchies. However, no FSH dosage caused more than one primordial follicle to initiate growth at one time. Alternation in follicular size between ovaries begins when a growing follicle develops a theca and is not controlled by alternation of primordial follicle growth initiation. Polyovular primordial follicles and a stromal inflammatory-like response are also described. These results are discussed in reference to the six kinds of germ cell and follicular selection occurring in the ovaries of A. carolinensis.
