Fetal sexual differentiation involves complex signaling and hormones for gonad determination and genitalia development. This review examines genetic models and disorders of sex development (DSD) to understand these processes.
Area of Science:
- Developmental Biology
- Endocrinology
- Genetics
Background:
- Fetal sexual differentiation is a precisely timed process involving intricate intracellular signaling and hormonal interactions.
- This developmental cascade establishes gonad determination and the formation of internal and external genitalia, leading to either a male or female phenotype.
Purpose of the Study:
- To review current knowledge on the mechanisms of gonadal determination.
- To integrate findings from genetic studies and clinical observations in disorders of sex development (DSD).
Main Methods:
- Analysis of knock-out and transgenic mouse models.
- Review of patient data from disorders of sex development (DSD) studies.
Main Results:
- Insights from genetic models highlight key genes and pathways regulating gonad development.
- Patient analyses reveal the phenotypic consequences of disruptions in sexual differentiation pathways.
Conclusions:
- Understanding fetal sexual differentiation requires integrating data from experimental models and human DSD cases.
- Further research into these interactions will elucidate the molecular basis of sex determination and DSD.

In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
