Radioimmunoassay of steroids produced by chick embryo gonads cultured in the presence of some exogenous steroid precursors.
TL;DR: Addition of precursors of sex hormones, such as pregnenolone, DHA, and Δ4-androstenedione to the culture media increases significantly steroid production, but in patterns appropriate with respect to the sexual differences observed in control gonads.

TL;DR: In vitro steroid production by quail gonads of control and of diethylstilbestrol (DES)-treated embryos (10 and 14 days) has been investigated by radioimmunoassay and the data indicate that, during normal development, ovaries produce mainly estradiol (E2) estrone and testes, testosterone (T).

Comparative study in steroidogenesis by quail and chick embryonic gonads in organ culture
TL;DR: The formation of progesterone and 4ene-androstenedione by gonads of both sexes demonstrates the presence of Δ 5 -3β HSD at this later stage of development.

Immunoreactive renin variations during fertile and infertile hyperstimulated cycles with in-vitro fertilization and embryo transfer or gamete intra-Fallopian transfer
TL;DR: The concentrations of prorenin (PR) and active renin (AR) were determined sequentially during ovarian hyperstimulated cycles for in-vitro fertilization-embryo transfer or gamete intra-Fallopian transfer to confirm the role of the renin angiotensin system in ovarian physiology.

Effects of early tamoxifen treatment on hormonal content of 15-day quail embryo gonads
TL;DR: The results indicate that the TAM treatment does not mainly modify the hormonal levels and patterns in the gonads of both sexes and does not inhibit the function of the hypothalamo-hypophyseal-gonadal axis.
