Spermatogenesis in fish
Spermatogenesis is a developmental process during which a small number of diploid
spermatogonial stem cells produce a large number of highly differentiated spermatozoa …

Estradiol and the develo** brain
Estradiol is the most potent and ubiquitous member of a class of steroid hormones called
estrogens. Fetuses and newborns are exposed to estradiol derived from their mother, their …

Ovarian steroid deprivation results in a reversible learning impairment and compromised cholinergic function in female Sprague-Dawley rats
We hypothesized that estradiol (E2) serves as a neurotrophomodulatory substance for basal
forebrain cholinergic neurons thought to be involved in learning and memory …

New insights into the regulation and function of brain estrogen synthase (aromatase)
In the brain, conversion of androgens into estrogens by the enzyme aromatase (estrogen
synthase) is a key mechanism by which testosterone regulates many physiological and …

Estradiol-17β stimulates the renewal of spermatogonial stem cells in males
In this work, we examined the functions of the female hormone “estrogen” on
spermatogenesis of the Japanese eel (Anguilla japonica). Estradiol-17β (E2), a natural …

Timing of breeding in variable environments: tropical birds as model systems
Animals need to adjust reproductive decisions to environmental seasonality. In contrast to
species from the well-studied temperate zones, little is known for tropical birds about the …

When is a sex difference not a sex difference?
Brain sexual differentiation in mammals requires activity of gonadal hormones;
organizational effects of these steroids on brain development occur early in life while …

Sexual differentiation of the rodent brain: dogma and beyond
Steroid hormones of gonadal origin act on the neonatal brain to produce sex differences that
underlie adult reproductive physiology and behavior. Neuronal sex differences occur on a …

Distribution and regulation of telencephalic aromatase expression in the zebra finch revealed with a specific antibody
In songbirds, aromatase (estrogen synthase) activity and mRNA are readily detectable in the
brain. This neural aromatization presumably provides estrogen to steroid‐sensitive targets …

Synaptocrine signaling: steroid synthesis and action at the synapse
Sex steroids have long been recognized for their dramatic impact on brain and behavior,
including rapid modulation of membrane excitability. It is a widely held perception that these …
