more hormones

Question 1

oestrogen as contraception

Answer 1

permanently high oestrogen means FSH production is permanently inhibited, so after a while egg development stops and stays stopped

Question 2

progesterone as contraception

Answer 2

progesterone prevents FSH production so that no eggs mature in the ovaries

Question 3

FSH in menstrual cycle

Answer 3

it’s produced in the pituitary gland, stimulates an egg to mature in the follicle and stimulates ovaries to produce more oestrogen

Question 4

oestrogen in the menstrual cycle

Answer 4

releases due to FSH, it’s released from the ovaries and causes the growth of the uterus lining, high levels then stimulate LH production and inhibit FSH secretion

Question 5

LH (luteinising hormone) in the menstrual cycle

Answer 5

LH is produced in the pituitary gland as a result of oestrogen, it triggers ovulation at day 14 where the follicle ruptured and the egg is released, the remains are then stimulated to form a structure called corpus luteum that secretes progesterone

Question 6

progesterone in the menstrual cycle

Answer 6

released from corpus luteum post ovulation, maintains uterus lining and if an egg is implanted would maintain high levels, high oestrogen and progesterone level inhibit LH and FSH production, low levels then restart the cycle

FSH, oestrogen, LH, progesterone
