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.

Refer to the paragraph on the orangutan breeding program. Which of the following hormones would you use if you want to induce ovulation right away?

vasopressin, LH, estradiol, progesterone, or testosterone?

luteinizing hormone (LH) is mainly used to induce ovulation.

Explanation:

Ovulation refers to the release of an egg.During menstruation  ovarian follicle discharges an egg.The egg is also known as an ovum, oocyte, or female gamete. It is only released on reaching maturity.

Ovulation induction uses hormonal therapy to stimulate egg development and release egg or ovulate.

By increasing the production of follicle stimulating hormone (FSH) by the pituitary gland, follicles are stimulated and hence egg growth is seen.

A surge in the Luteinizing hormone (LH) causes the egg to release or ovulate. Luteinizing hormone (LH) is produced and released in the anterior pituitary gland. This hormone is a gonadotrophic hormone and plays an important role in controlling the function of ovaries in females and testes in males.

In women, the hormone stimulates the ovaries to produce oestradiol. Two weeks into a woman's cycle, a surge in luteinizing hormone causes the ovaries to release an egg during ovulation. If fertilization occurs, luteinizing hormone will stimulate the corpus luteum, which produces progesterone to sustain the pregnancy.
