Final answer:
Medication is the preferred treatment for prolactin-secreting adenomas, while it has no significant effect on gonadotropin-secreting adenomas.
Step-by-step explanation:
The preferred treatment for prolactin-secreting adenomas (prolactinomas) is medication.
These medications, such as dopamine agonists, work by inhibiting the release of prolactin from the pituitary gland.
However, they do not have a significant effect on gonadotropin-secreting adenomas, which are tumors that secrete follicle stimulating hormone (FSH) and luteinizing hormone (LH).
