In a female undergoing infertility treatments, which drug is likely included to induce ovarian follicular growth?

Follitropin is the appropriate medication included in infertility treatments to induce ovarian follicular growth. This drug is a recombinant form of follicle-stimulating hormone (FSH), which is crucial in the development of ovarian follicles. By stimulating the ovaries, follitropin helps to promote the maturation of oocytes, which can enhance the chances of ovulation and successful conception.

In contrast, cabergoline is primarily used to treat conditions such as hyperprolactinemia and is not focused on ovarian stimulation. Methimazole is an antithyroid medication that controls hyperthyroidism and has no role in ovarian follicle development. Vasopressin assists with water retention in the kidneys and does not influence ovarian function directly. Therefore, follitropin stands out as the drug specifically designed to support the follicular growth needed in the context of infertility treatments.
