Tests made on the ovarian tissue at different stages of the reproductive cycle showed that
steroid metabolism in Zoarces viviparus follows the same pathways as in oviparous teleosts …

Ovarian tissue of the teleost Centropristes striatus was incubated with labeled pregn-4-ene-
3, 20-dione (progesterone) and 17β-hydroyyandrost-4-ene-3-one (testosterone). Using …

Ovaries of dogfish were separated into their component tissues and incubated separately
with [4-14 C] dehydroepiandrosterone and androstenedione. Production of Δ 4-3 …

1. From ovarian minces of pre-and post-spawned Tilapia aurea incubated with
pregnenolone-7α-3 H, thirteen radioactive peaks were isolated. 2. 2. Six radiometabolites …

1. Steroid hormone production in the mature ovary of the hagfish Eptatretus burgeri was
demonstrated in vitro using labeled precursors of steroid hormones. 2. 2. Progesterone, 17α …

1. Homogenates of ovaries of 3-and 12-month-old guppies were incubated with
pregnenolone-7α-3 H and progesterone-4-14 C, and with androstenedione-1, 2-3 H …

Homogenates of ovaries of the rainbow trout were incubated with pregnenolone-7 alpha-3H
and androstenedione-7 alpha-3H during 4 stages of the reproductive cycle. During …

In vitro steroidogenesis in the mature ovaries of a freshwater teleost, the ayu (Plecoglossus
altivelis), was examined. Cell-free homogenates of the ovaries of untreated fish or fish …

Steroid concentrations in plasma and follicular tissues (theca plus granulosa layers) were
determined by radioimmunoassay in the aplacental viviparous ray, Torpedo marmorata …

Ovarian tissue homogenates of a teleost, Tilapia aurea, were incubated in vitro with
radioactive precursors of steroids and with labeled acetate with the following results: From …
