Q

desribe what happens in the testes of a klinefelters patient

A

seminiferous tubules are destroyed and hyalinized resultin in small fir testes
inhibitin levls decreasese
leydig cells become damaged and hvae lower testosteron

Q

what gene is responsbile for short stature in turner

19
Q

diagnose:
increased testosterone
increased LH

A

defective androgen receptor

20
Q

diagnose:
increased testosterone
decreased LH

A

testosterone secreting tumor

exogenous steroids

21
Q

diagnose:
decrease testosterone
increased LH

A

primary hypogonadism

22
Q

diagnose:
decreased testosterone
decreased LH

A

hypogonadotropic hypogonadism

23
Q

testo and LH in defective androgen receptor please

A

increased testosterone and increased LH

24
Q

testo and LH in testosterone secreting tumor or exogenous steroids please

A

increased testosterone and decreased LH

25
testo and LH in primary hypogonadism
decreased testosterone adn icnreased LH
26
testo and LH in hypogonadotropic hypogonadism
decreased testosteroen and decreased LH
27
what is pseudohermaphroditism?
disagreement betwen the phenotypic/external genitalia and gonadal/testes vrs ovaries sex
28
what is femal pseudohermaphrotie
XX ovaries external genitalia: virilized or ambiguss
29
what can cause female pseudohermaphrodite
congenital adrenal hyperplasia exogenous andrognes in pregos adrenogenital syndrome
30
what is male pseudohermaphrodite
XY testes external genitalia: female or ambiguous
31
what can cause male pseudohermaphroditism
androgen insensitivity syndrome MOST COMMON | 5 alpha reductase deficiency
32
describe geneotype and pheontypic apperance of aromatase deficiency
female XX | masculiniztaion due to lack of estrogen productino since aromatse is gone so will have ambiguous genitalia.
33
serum - increased testosterone and androstenedione | maternal virilization during pregnancy
aromatase deficiency
34
descibre the genotype and phenotype in androgen insensitivity syndrome
46 XY testes usually in labia majora no internal male - no androgen response in mesonephric duct no internal female - suppressed by MIH from sertoli cells no external male - no response to DHT will have blunt vagina bc bottom of vagina ceoms from urogenital sinus
35
what causes androgen insensitivity syndrome
46 XY male with defect in androgen recptor | XLR
36
hormone changes in androgen sensitivity syndrome
increased testosterone increased LH increased estrogen = cant have negative feedback bc receptor doesnt work
37
describe genotype and phenotype in 5alpha reductased deficiency
AR 46XY cannot convert testosterone to DHT internal: MIH and androgens cause SEED (seminal vesicles, epididymis, ejaculatory duct, ductus deferens) and suppress internal external - ambiguous until puberty when testosterone causes masculinization and growth of external genitalia
38
hormones in five alpha reductased def please
testosterone normal estrogen normal LH increased or normal
39
what is kallmann sndromes pathogenesis
a form of hypogonadotropic hypogonadism defective migration fo GnRH cells and formation fo olfactory bulb -- decrease GnRH in hypothalamus - failure to complete puberyu
40
hormone levels in kalmann syndrome please
decreased GnRH decreased FSH decreased LH decreased testosterone
41
fertility in kallmann syndrome please
infertility low sperm count in males amenorrhea in females
42
anosmia | infertility
kallmann syndrome
43
knuckle knuckle dimple knucle
turner syndrome
