Presentation of PPHN?
Rx?
RDS, cyanosis, loud S2
Supportive, inotropes
Male repro duct?
Male - Wolffian duct/mesonephric
Female - Mullerian/paramesonephric
How does male/female differentiation occur?
If Y chromosome then testes sectete testosterone (wolffian duct grows) and anti-mullerian hormone (mullerian duct degenerates)
If no Y chromosome absence of testosterone (wolffian duct degenerates) and absence of anti-mullerian hormone (mullerian duct grows)
Presnce/absence of testosterone causes development of male/female genitalia
Presence/absence of anti-mullerian hormone causes development of male/female repro tract
When does sex differentiation occur?
When is it seen on USS?
9 weeks
16 weeks
What is androgen insensitivity syndrome?
Congenital insensitivity to androgens
46 XY genotype but female phenotype - X-linked recessive
Testes develop but do not descend
Mullerian inhibition occurs so testes, and short vagina
Presents at puberty with primary amenorrhoea and failure to develop secondary sexual characteristics
Management of cryptorchidism? (undescended testes)
Orchidoplexy if <14y/o
If adult then orchidectomy (6x risk of testicular germ cell cancer)
Function Leydig cells?
Sertoli cells?
Leydig - release testosterone in response to LH
Sertoli - form blood/testicular barrier, nutrients, phagocytosis, secrete inhibin/activin, secrete androgen binding globulin
Release of LH/FSH in males?
Controlled by GnRH, under -ve feedback from testosterone
Function of activin and inhibin?
Inhibin prevents FSH release
Activin causes FSH release
