Study Notes

  1. Sexual differentiation is the process of becoming male or female during embryonic development.
  2. Sexual determination is a molecular switch that determines the pathway an embryo will take.
  3. Gonadal sex is the first thing that develops to identify whether the fetus is male or female.
  4. The SRY gene on the Y chromosome determines gonadal sex.
  5. The development of internal and external genitalia is influenced by the products of the pair of gonads.
  6. 5α-reductase is an enzyme that converts testosterone to DHT, which causes differentiation of the male external genitalia.
  7. Disorders of sexual differentiation include gonadal dysgenesis, sex reversal, and intersex.
  8. Androgen Insensitivity Syndrome (AIS) occurs when a patient is XY and makes testosterone, but it has no effect.
  9. Patients with complete AIS appear totally female at birth and are assigned the female gender despite having an XY.
  10. Terms such as 'pseudohermaphrodite' and 'testicular feminisation' are now obsolete.
  11. Undescended testes can be a sign of gonadal dysgenesis.
  12. Primary amenorrhoea and lack of body hair can indicate gonadal dysgenesis.
  13. Karyotyping can reveal the XY genotype despite a female phenotype in gonadal dysgenesis.
  14. Turner's syndrome is a genetic disorder that results in female external genitalia.
  15. Congenital adrenal hyperplasia can cause both male and female internal genitalia.
  16. The HPG axis is flawed in congenital adrenal hyperplasia.
  17. The lack of aldosterone in congenital adrenal hyperplasia can cause salt wasting.
  18. Glucocorticoid treatment is necessary in congenital adrenal hyperplasia.
  19. Surgery is now optional for partial AIS treatment.
  20. Turner's syndrome is a spectrum disorder.
