embryo Flashcards
testis fails to descend. undescended testis fail to produce mature spermatozoa and may be associated with renal anolmalies
Cryptochidism
abnormal positions of testis under the skin of any where along the lower part of the abdomen: thigh, femoral canal, penis, behind scrotum
Ectopia
non formation of testies
Agenesis
in male, urethral folds become what?
penile urethra
genital/scrotal swelling becomes?
scrotum
in male, genital tubercle becomes what?
glands of penis
in female, genital tubercle becomes?
clitoris
in female, genital swelling becomes?
labia majora
in female, urethral fold becomes
labia minora
these parts of urethra are formed by the vesicourethral canal of the UG sinus
prostatic and membranous parts of urethra
posterior wall of prostatic urethra above the level of opening of the ejaculatory duct is developed from what?
absorbed part of the mesonephric duct
definitive UG sinus and fusion of the urethral folds(endoderm) form which part of urthra?
spongy urethra
female urethra is developed from what?
vesicourethral canal
47, XXY. phenotypically males with infertility, impaired sexual maturation, underandrogenization
klinefelter syndrom
phenotypically female, but may have XY chromosome complement. no oocyte; malformed gonads
gonadal dysgenesis
45, XO short stature; gonadal dysgenesis
Turner syndrome
deletion of SRY gene resulting in no secondary sexual characteristics
XY female gonadal dysgenesis “swyer syndrome”
have both testis adn ovary - usually combined as ovotestes karyotype is 46, XX; usually a uterus; ambiguous external genitalia
True hermaphrodites
genotypic sex is masked by the phenotype appearance o fother sex
pseudohermaphrodites
46, XX caused by congenital adrenal hyperplasia
female pseudohermaphroditism
x-linked recessive disorder; lack of androgen receptor
ext. genitalia are female/patient has 46XY karyotype&testes
medially, legally, and socially these individuals are females
testicuilar feminization syndrome
androgen insensitivity syndrome
