Answer:
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.

Hello, our reflexes are governed by the spinal cord since these actions happen quickly thus needing to bypass the brain. The other functions, meanwhile, are controlled by the brain itself, with motor skills and involuntary functions such as respiration being controlled by different parts of the brain.
