For your internship at the local zoo, you have been assigned to help with the new orangutan-breeding program. Little is known about orangutan reproductive hormones, but hormone feedback cycles are often the same in closely related animals. You have been asked to use your knowledge of the interactions of human reproductive hormones to recommend injections to promote ovulation in a female orangutan when a visiting male arrives for a brief breeding visit.
-Which of the following hormones would you use if you want to induce ovulation right away?

LH is responsible for inducing ovulation in females, including humans. Therefore, it would likely have a similar effect in orangutans. Oestradiol and FSH are both involved in regulating the menstrual cycle, but not directly responsible for inducing ovulation. Progesterone is involved in maintaining the pregnancy after ovulation has occurred.
