Background: Hypospadias is a common malformation of male external genitalia, resulting in urethral displacement with different severity. Male genital development occurs during fetal development when also the brain is developing rapidly. Genital development is dependent on androgen effect, and androgens also have impact on gender development. We here explore whether hypospadias are associated with variation in other aspects of sex typical development.<p c...

We demonstrate significant penile growth in an infant with 17 beta HSD-deficiency treated with DHT-gel.Background: The child was born with ambiguous genitalia at full term. Investigations revealed 46,XY karyotype, testosterone and DHT levels were 2.5 nmol/L and <0.1 nmol/L respectively. No female internal genitalia were found. hCG stimulation did not result in an increase in testosterone, but a clinically obvious increase in phallus size. Subsequent ...

Background: Congenital adrenal hyperplasia (CAH), due to 21-hydroxylase deficiency is one of the most common monogenic autosomal recessive disorders with an incidence of one in 15 000, and even more common in some populations. Do carriers have a survival advantage?Objective and hypotheses: The HPA axis has been reported to be more active in CYP21A2 carriers, and possibly enable a more rapid return to homeostasis. A compensatory increase in CRH s...

Background: Congenital adrenal hyperplasia (CAH) is a relatively common monogenic recessive disorder with an incidence of 1/15 000 in most populations. It has been suggested that CYP21A2 deficiency is relatively common because it may confer a survival advantage to be a carrier. Carriers of CYP21A2 mutations typically do not have clinical symptoms but have a defined phenotype. The cortisol response to ACTH stimulation has been shown to be both...
