What hormone needs to spike to signal ovulation?
A
FSH
B
LH
C
Estrogen
D
Progesterone
Explanation: 

Detailed explanation-1: -The hypothalamus secretes GnRH in a pulsatile fashion, which triggers FSH and LH release from the anterior pituitary. These, in turn, act on the granulosa and theca cells in the ovary to stimulate follicle maturation and trigger ovulation.

Detailed explanation-2: -Ovulation is spontaneously triggered about 36-40 hours after blood levels of a hormone called luteinizing hormone (LH) rise. This is called the LH surge. Once released from the ovary, the egg is picked up by and travels down the fallopian tube where it can meet sperm to become fertilized.

Detailed explanation-3: -Ovulation: A surge in LH causes your ovary to release a mature egg around the second week of each menstrual cycle. A high LH level around this time means that you’re at that moment in your cycle when you’re most likely to get pregnant.
