TLDR
A two-cell-type model for the production of follicular estrogens, the thecal layer possibly contributing to estradiol-17β production by synthesizing androgens which are transferred to the granulosa layer and aromatized to est radiol- 17β is suggested.About:

The effects of salinity on reproductive performance and plasma levels of sex steroids in Caspian kutum Rutilus frisii kutum
TL;DR: Results of this study indicate that salinity plays a minor, but vital, role in reproduction of kutum, a factor that needs to be considered for keeping broodstock of brackish water fish species like kutums.
Influence of Exogenous Gonadotropin and Sexual Steroids on Ovary Development in Japanese Eel Anguilla japonica
Yung-Song Wang,Show-Wan Lou +1 more
TL;DR: The synergistic effect of SPH plus MT revealed that MT, a potent, aromatizable androgen, provides a potential usefulness to participate the process of vitellogenesis when it combines with SPH treatments, and actually enhances the survival and synchronous development of ovarian follicle throughout the reproductive process.

Reproductive hormone profiles and gametogenesis in female of giant gouramy (Osphronemus gouramy)
TL;DR: Information of gonadotropin, estradiol-17 and progesterone profiles, and gametogenesis of giant gouramy could be useful on the effort to optimize their reproductive performance.

Ovarian follicular development in the rat: hormone receptor regulation by estradiol follicle stimulating hormone and luteinizing hormone.
J. S. Richards,James J. Ireland,Mrinalini C. Rao,G. A. Bernath,A. R. Midgley,Leo E. Reichert +5 more
TL;DR: The results indicated that follicular development and granulosa cell differentiation are dependent on steroid-protein hormone regulation of hormone specific receptors.
Journal ArticleDOI
Granulosa cell maturation in the rat: increased binding of human chorionic gonadotropin following treatment with follicle-stimulating hormone in vivo.
TL;DR: Results suggest that FSH administered in vivo may act on granulosa cells to induce or activate receptors for I_H (hCG) and 3β-hydroxysteroid dehydrogenase activity as well as stimulate follicle-stimulating hormone in ovarian development.
Journal ArticleDOI
Site of production of oestrogen in rat ovary as studied in micro-transplants.
TL;DR: It is concluded that the theca interna gland cells and the interstitial gland cells most probably constitute the oestrogen-producing system in the ovary but that these cells are functionally dependent on the system granulosa-corpus luteum cells.

Seasonal changes in plasma cortisol, testosterone and oestradiol-17β in the plaice, Pleuronectes platessa L
J.C. Wingfield,A.S. Grimm +1 more
TL;DR: Plasma cortisol levels are at a high during the season of poor feeding when mobilisation of energy reserves is likely to be greatest and steroid concentration in males showed small significant seasonal changes.

Androgen production by theca and granulosa isolated from proestrous rat follicles.
J. E. Fortune,David T. Armstrong +1 more
TL;DR: It is concluded that the theca is the site of follicular androgen production and that LH regulates androgen secretion by rat ovarian follicles, and provides the androgen precursor needed for follicular estradiol-17beta synthesis.
