“…Several recent reviews, including those of Odell & Swerdloff (1976) and Ramaley (1979) The gradual increase in prolactin levels as the male mice approached puberty is similar to that reported by Barkley (1979). The temporal difference observed in males and females for the samples taken at noon and midnight has also been found by Sinha, Salocks, Wickes & Vanderlaan (1977).…”

“…A similar elevation in gonadotrophin concentrations is seen in the prepubertal female rat before the onset of puberty (Ramaley, 1979). This increase in rabbit gonadotrophins was associated with maximum opiate binding in the hypothalamus (Wilkinson & YoungLai, 1986).…”

“…Gonadotropins may also play a supporting role in this process. It is known, in many mammalian species, that a transient increase in concentrations of circulating gonadotropins occurs in the early prepubartal period [19,25]. A transient increase in follicular number was also reported in these animals [19].…”

Abstract. This study describes the morphological and morphometrical changes associated with prepubertal ovarian development in the Antarctic minke whale (Balaenoptera bonaerensis). Ovaries were harvested from 94 immature minke whales caught in the Antarctic Ocean during the summer feeding season (December-March). Notable differences in ovarian size and morphology were found among animals. Up to 10 folds difference in ovarian weight was found among prepubertal whales of similar body size. During the prepubertal period, ovaries grew slowly and approximately doubled their weight. The morphologies of right and left ovaries were almost identical while the growth of the ovary appears to occur preferentially on the right side. The most striking morphological feature was numerous small antral follicles less than 5 mm in diameter found in ovaries of younger immature whales. The occurrence of these ovaries was highest in whales less than 6 m long and gradually decreased as body length increased. In larger whales, the occurrence of ovaries with a smaller number of follicles up to 10 mm and thick tunica albuginea increased. Thus, the ovary of the Antarctic minke whale experiences bursts of small follicular development during the early prepubertal period before becoming a more developed ovary with fewer but larger follicles, and thick tunica albuginea.
