Estrogen (a female sex hormone) levels continuously increase during a woman's menstrual cycle. Estrogen levels drop once menstruation occurs (the ovaries stop releasing estrogen).Is this an example of positive or negative feedback?

Please draw a feedback loop for an individual who has secondary hypogonadism and is receiving testosterone replacement therapy.   Would there be an excess amount of GnRH or a low amount? And does the testosterone feedback to anywhere or is it even possible to create a negative feedback loop for this?

Read the following passage: When oestrogen concentration is high it stimulates the release of LH. LH stimulates the ovaries to release more oestrogen. State whether this is an example of negative or positive feedback and which organs are involved. Explain your answer.

Both pituitary (FSH and LH) and ovarian (estrogen and progesterone) hormones are involved in regulating the menstrual cycle.

LH, FSH, estrogen, progesterone b. FSH, estrogen, progesterone, LH c. FSH, estrogen, LH, progesterone d. FSH, LH, estrogen, progesterone

Which of the following statements is NOT about follicle stimulating hormone (FSH) in the male reproductive system? Select one: a. It increases the production of inhibin. b. It is suppressed by increased levels of testosterone and inhibin. c. It is stimulated by GnRH and LH. d. It stimulates the seminiferous tubules to produce sperm.

If progesterone and estrogen were set at artificially moderately high levels for a long period, what would result?

Choose between LH, inhibin, FHS and testosterone
