Question

Ovulation is brought about by the hormone of pituitary gland which is called

• A. Follicle stimulating hormone
• B. Luteinizing hormone (LH)
• C. Luteotropic hormone (LTH)
• D. Estrogen

Answer 1

Answer: (B)

Luteinizing hormone (LH)

Luteinizing hormone is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH triggers ovulation and development of the corpus luteum. LH supports theca cells in the ovaries that provide androgens and hormonal precursors for estradiol production. With the rise in estrogens, LH receptors are also expressed on the maturing follicle, which causes it to produce more estradiol

So, the correct answer is 'luteinizing hormone (LH)'
