Final answer:
To treat a luteal cyst, a hormone that affects the corpus luteum would be administered. Luteinizing Hormone (LH) naturally stimulates the corpus luteum, but in treatment, leuprolide acetate or human chorionic gonadotropin (hCG) might be used instead.
Step-by-step explanation:
To treat a luteal cyst, one would likely administer a hormone that regulates the functionality of the corpus luteum and the luteal phase of the menstrual cycle. The hormone commonly associated with stimulating the corpus luteum is Luteinizing Hormone (LH), which encourages its formation from the follicular tissue left behind after ovulation.
However, in certain fertility treatments, a different approach is used. Drugs like leuprolide acetate (Lupron) may be injected to block secretions from the pituitary gland, optimizing oocyte retrieval. Alternatively, human chorionic gonadotropin (hCG) can be used, which mimics the action of LH and can both induce ovulation and support the corpus luteum after fertilization to maintain a new pregnancy by stimulating it to continue producing progesterone.
