Sexual Differentiation of the Brain
1981Publisher Summary This chapter discusses the sexual differentiation of the brain. In the mediobasal hypothalamus the gonadotropin-releasing hormone (GnRH) is secreted under the influence of neurotransmitters. It is transported by the hypothalamic-hypophysial portal vessels to the anterior pituitary, stimulating there the secretion of gonadotropins ...

Sexual differentiation is a sequential process that begins at fertilization with the establishment of chromosomal sex, continues with the determination of gonadal sex, and culminates in the development of secondary sexual characteristics that comprise the male and female phenotypes.

Neurosteroids and brain sexual differentiation
Trends in Neurosciences, 2001There is new evidence that the brain of developing songbirds can synthesize estradiol de novo. In males, this neurally derived estrogen might masculinize a connection within the neural song system. These results challenge traditional concepts about mechanisms of brain sexual differentiation and reveal a significant function for neurosteroids.

The Origin of Isogamous Sexual Differentiation
1991It is a general biological rule that sexual reproduction invariably involves the fusion of gametes of two different types. Most evolutionary biologists presume that the differentiation of gametes into mating types started within a primordial population consisting entirely of undifferentiated gametes. However, none of the population genetical models for

Sexual Differentiation in Volvox aureus*
The Journal of Protozoology, 1966SYNOPSIS. The complete life history of a homothallic, dioecious strain of Volvox aureus was studied in axenic culture. Asexual reproduction occurs by repeated division of specialized reproductive cells (gonidia), inversion of the resultant mass of cells to form daughter colonies, and subsequent morphologic differentiation of new gonidia in these ...
