Introduction
Practical 12: Sex Determination | Early Embryo | Late Embryo | Fetal | Postnatal | Abnormalities | 2011 Audio |
This practical will introduce the topic of sexual differentiation during development through a series of online resource pages.
Aim: This practical is an introduction to the earliest events in Sexual Differentiation.
Key Concepts: Primordial germ cells, gonad, internal genitalia, external genitalia, ovary, testes, puberty, hormonal changes, gametogenesis, abnormalities.

Introduction
Two key systems, neural and reproductive, develop over an extended period from the early embryo to puberty and the emerging adult. Interestingly, recent research is pointing to a link between these two systems in how male and female brains may differentially develop under the influence of sex hormones and perhaps even the sex chromosomes.
In understanding embryonic sexual development, think of a cascade of sequence dependent events that transform indifferent gonads, internal and external genitalia into distinct male and female structures. The process begins with gonad differentiation, which itself is tied developmentally back at the initial event of fertilization and the presence of either a Y or X chromosome in the sperm.
The endpoint of development could be considered the post-puberty active reproductive system. Though in these modern times, this too is regulated/delayed by our own neurological desire, or lack thereof, to reproduce.
