rugosa were reared in water containing the dosage of T, which enabled us to detect primary changes in the histology of the masculinizing gonads. In this study, we determined a threshold dosage of estradiolβ (E2) to cause male‐to‐female sex reversal in this frog. We observed first signs...

Tanya is in the midst of female climacteric, when levels of the hormone estrogen drop in women as they become less fertile. There are several symptoms of female climacteric, including hot flashes (which involves feeling hot), hot flushes (which involves looking flushed), headaches, insomnia, col...
Photo: Whether an individual in the all-female lizard species Cnemidophorus uniparens acts as a male or female in pseudocopulatory events appears to be regulated by cyclic levels of the female sex hormones estrogen and progesterone, which control ovulation. Leaping lizards and male impersonators: ar...
Indeed, appropriate levels of circulating TST and gonadal hormone receptor expression are required to sustain the typical male preference for female odours24,25,26,27. We found a strong decrease in circulating TST levels in Sema7A ko compared to wild-type (wt) mice (Fig. 1A). TST acts ...
The present experiment was performed to test the hypothesis that gender differences in the capacity for brain estrogen synthesis could constitute a sexually dimorphic mechanism that limits the activational effects of testosterone (T) in females, and enhances them in males. We determined the effects of...
Gonadally intact pseudohermaphroditic female and normal female and neonatally castrated male rhesus monkeys were given estrogen treatment as adults and evaluated for attractivity, proceptivity, and receptivity during tests with a tethered stud male. Pseudohermaphrodites were produced by injecting their moth...
