    As per the prenatal androgen theory, female homosexuality takes place as a result of

  • underexposure to estrogen
  • overexposure to prenatal androgen
  • overexposure to testosterone
  • underexposure to prenatal androgen
  • 2. 
    What is the reason why some human females tend to develop male characteristics such as degeneration of ovaries and uterus, beard, enlargement of the clitoris?

  • surgical removal of mammary glands
  • overproduction of adrenal androgens
  • damage to the posterior pituitary
  • overproduction of estrogen and testosterone
  • 3. 
    This is Addison’s disease

  • Involves a long-term endocrine disorder in which the adrenal glands do not produce enough steroid hormones
  • Involves the overproduction of cortisol and aldosterone by the adrenal cortex
  • Involves the overproduction of androgens by the adrenal medulla
  • Involves the underproduction of androgens by the adrenal medulla
  • 4. 
    This hormone in males triggers Sertoli cells to synthesize androgen binding globulin (ABG)

  • Gonadotropin releasing hormone (GnRH)
  • Luteinizing hormone (LH)
  • Oxytocin
  • Follicle-stimulating hormone (FSH)
  • 5. 
    When chemical signals are produced by entities, it influences the behaviour of other entities belonging to the same species This is known as

  • Steroid
  • Androgen
  • Insulin
  • Pheromone
  • 6. 
    This is the effect of GnRH secreted by the hypothalamus

  • triggers the synthesis of carbohydrates from non-carbohydrates in liver
  • triggers foetal ejection reflex
  • triggers secretion of milk in the mammary glands
  • triggers the synthesis and secretion of androgens
  • 7. 
    This condition results in females that secrete large quantities of androgens

  • Addison’s disease
  • Adrenal hyperplasia
  • Both of these
  • None of the above
  • 8. 
    The adrenal glands in hyperplasia produce high quantities of this substance

  • Estrogen
  • Androgen
  • Glucocorticoids
  • Adrenaline
  • 9. 
    This conduction is most likely to occur if the developing foetus is not sensitive to the effects of testosterone and other such androgens

  • Klienfelters syndrome
  • Von Willebrand’s disease
  • Waardenburg’s syndrome
  • Testicular feminisation syndrome
  • 10. 
    The receptor cells in the hypothalamus of the developing males in the womb are unresponsive to

  • estrogen
  • androgen
  • gonadotropins
  • testosterone
