Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which hormone signals ovulation?
A
FSH
B
LH
C
Inhibin
D
Estrogen
Explanation: 

Detailed explanation-1: -Leutinizing hormone (LH), the other reproductive pituitary hormone, aids in egg maturation and provides the hormonal trigger to cause ovulation and the release of eggs from the ovary.

Detailed explanation-2: -The LH surge signals that ovulation is about to start. Ovulation is the medical term for an ovary releasing a mature egg. A gland in the brain, called the anterior pituitary gland, produces LH. Levels of LH are low for most of the monthly menstrual cycle.

Detailed explanation-3: -Luteinizing hormone is a part of a neurological pathway comprised of the hypothalamus, the pituitary gland, and gonads. In this pathway, LH release is stimulated by gonadotropin-releasing hormone (GnRH) and inhibited by estrogen in females and testosterone in males.

Detailed explanation-4: -Luteinizing hormone (LH) plays a key role in gonadal function. LH in synergy with follicle stimulating hormone (FSH) stimulates follicular growth and ovulation. Thus, normal follicular growth is the result of complementary action of FSH and LH.
