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. 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 channel.

** Presence of [[wolffian]] [[duct]] [[derivatives]] ([[epididymus]], [[vas deferens]], and [[seminal vesicles]]).
** Progressive [[virilization]] at the time of puberty, both of which depend on the action of [[testosterone]].  
*During puberty, individuals with this [[disease]] develop some male [[secondary sex characteristics]], such as increased [[muscle mass]], [[deepening of the voice]], and development of male pattern facial and body hair.
*Some affected individuals may also experience [[gynecomastia]]. People with this disorder are generally [[infertile]].<ref name="pmid17509588">{{cite journal| author=Mains LM, Vakili B, Lacassie Y, Andersson S, Lindqvist A, Rock JA| title=17beta-hydroxysteroid dehydrogenase 3 deficiency in a male pseudohermaphrodite. | journal=Fertil Steril | year= 2008 | volume= 89 | issue= 1 | pages= 228.e13-7 | pmid=17509588 | doi=10.1016/j.fertnstert.2007.02.048 | pmc=2259022 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=17509588  }} </ref>

Overview

The characteristic phenotype at birth is an XY individual with female or ambiguous external genitalia. The majority of those affected have female external genitalia and consequently are raised as girls.
