Overview
- 17-beta-hydroxysteroid dehydrogenase deficiency-3 is clinically characterized by either ambiguous external genitalia or complete female external genitalia at birth; As a consequence of impaired male sexual differentiation in 46 XY individuals.
History and Symptoms
- 17-beta-hydroxysteroid dehydrogenase deficiency-3 is clinically characterized by either ambiguous external genitalia or complete female external genitalia at birth, as a consequence of impaired male sexual differentiation in 46XY individuals.
- Further investigations on ambiguous genitalia will eventually lead to findings of intersexuality.
- Severely impaired virilization (often complete absence of male sexual differentiation) can lead to development of female external genitalia.
- These females are often discovered when there is absence of menarche (first menstruation) and when they begin to virilize during puberty (slowly become more like a man; deepening of the voice, acne, male musculature etc).
- At careful examination, testis can often be found in the inguinal canal.[1]
