Area of Science:

  • Reproductive Biology
  • Endocrinology
  • Genetics

Background:

  • Testis formation initiates male sex differentiation, regulated by androgens.
  • Disorders of sex differentiation provide insights into androgen action mechanisms.

Purpose of the Study:

  • To elucidate the cellular and molecular mechanisms of androgen action.
  • To identify developmentally regulated androgen-responsive genes.
  • To investigate the role of androgen receptor gene polymorphisms in male under-masculinization.

Main Methods:

  • Studying male sex differentiation disorders.
  • Analyzing the androgen receptor's function as a ligand-induced transcription factor.
  • Conducting preliminary studies to identify androgen-responsive genes.

Main Results:

  • The androgen receptor plays a pivotal role in male development.
  • Preliminary studies are underway to identify key androgen-responsive genes.
  • Androgen receptor polyglutamine repeat polymorphisms influence male under-masculinization.

Conclusions:

  • Androgen action is central to male sexual development.
  • The androgen receptor is a key mediator, and its polymorphisms can affect outcomes.
  • Further research into androgen-responsive genes is warranted.
