Definition
informs gonadal sex of chromosomal sex. gonads then give hormonal output which informs phenotypic sex. |

Term
DHT AND androgen receptor |
|
Definition
vs. no DHT OR no androgen receptor. external genitalia. |

|
|
Term
what do you need for evaluating for DSD? (6) |
|
Definition
absence of testes in males (but otherwise normal phenotype) and vice versa, OR hypospadias + undescended testis, OR perineal hypospadias. Female- clitoral hypertrophy, hernia with gonad, fused labia minora |
|

|
|
Term
exogenous reasons for virilization of females |
|
Definition
only 10% of cases; tumor, or maternal adrogen ingestion |
|
|
Term
|
Definition
21-hydroxylase (90% cases), 50-65% of them present with vascular collapse and salt wasting, increased 17-OH progesterone in the serum. 11-beta hydroxylase: salt retention. 3 beta ol dehydrogenase: rare, fatal, severe salt wasting, ambiguous genitalia in BOTH sexes |
|
|
Term
indication for CAH screening / what to test |
|
Definition
previous child with it. test for 17-hydroxyprogesterone(2nd trimester only), 21-hydroxylase gene |
|
|
Term
|
Definition
2nd trimester; 1st trimester = chorionic villous sampling |
|
|
Term
|
Definition
dexamethasone - begin at 6th week to prevent adrenal androgen production |
|
|
Term
where can things go wrong in male sexual differentiation (4) |
|
Definition
androgen receptor, testosterone, 5alpha-reductase, MIF |
|
|
Term
|
Definition
X-linked recessive, amenorrhea, inguinal hernia with testis in female, maybe ambiguous genitalia, maybe palpable gonads in a female = testicular feminization |
|
|
Term
5alpha-reductase deficiency |
|
Definition
pseudo-vaginal perineoscrotal hypospadias, inguinal testes palpable, nonvirilized until puberty |
|
|
Term

Definition
buccal smear (barr body, fluorescent), karyotype (FISH) |
|
|
Term
ambiguous genitalia biochemistry (6) |
|
Definition
serum more effective than urine; serum: electrolytes, testosterone, 17-OH progesterone. urine: 17 ketosteroid (steroids), 17 OH P |
|
|
Term
determining sexual assignment (5) |
|
Definition
prognosis for fertility, sexual orientation, gender identity, underlying etiology of ambiguity, appearance and prospect for reconstruction |
|
|
Term
|
Definition
feminization of boys and girls, virilization of boys, removing potentially cancerous gonads |
|

Definition
|
|
Term
if surgery to change sex of rearing is done neonatally |
|
Definition
testosterone probably won't matter, but if done at age 6 months then it won't "work". = neonatal imprinting, prenatal imprinting |
|
|
Term
|
Definition
at least half boys changed to girls had gender identity issues. maximal testosterone imprinting. REINER data. |
