Answer:
The correct answer will be- Aromatization hypothesis
Step-by-step explanation:
Traditionally it was believed that giving testosterone to the human makes the brain masculine and its effect depends on the estrogen receptors.
The testosterone hormone (androgen) produced from the testis enters the brain which there gets converted to 17-β estradiol (E2) by aromatase enzyme which acts on the estrogen receptors and develops the rodent brain.
Since the pathway involves the enzyme aromatase, therefore, aromatization hypothesis is the correct answer.
