Here are a few simple Quiz questions that relate to Abnormalities of genital development from the lecture and practical.

1

In a genetic male (44 x XY) who lacks androgen receptors, each of the following will be increased except:

  estradiol
  FSH
  LH
  progesterone
  testosterone

2

The best option below for a child born with ambiguous external genitalia could be:

  46,XX DSD a female pseudohermaphrodite
  46,XY DSD a male pseudohermaphrodite
  Ovotesticular DSD
  someone with Klinefelter’s syndrome
  any of the above

3

In monosomy XO (Turner’s syndrome):

  the children start normal male development
  the number of germ cells in the gonads starts decreasing after puberty
  the children grow disproportionately tall
  an active gene on a dormant X chromosome may account for the clinical manifestations
  all of the above might occur

4

If 46,XY DSD is due to androgen receptor disorders, then:

  the testes are normal for the most part
  the testosterone and DHT levels are normal
  MDIF is secreted by the Sertoli cells
  the fetus will have female external genitalia without a female genital tract
  all of the above is correct

5

Failure of formation and migration of the primordial germ cells results in:

  Turner’s syndrome
  Klinefelter’s syndrome
  46,XX DSD
  gonadal agenesis
  none of the above

6

Failure of the urethral folds to fuse prenatally would be expected to result in:

  epispadias
  exstrophy of urinary bladder
  horseshoe kidney
  hypospadias
  multiple ureters
