The ovaries produce progesterone. Changing progesterone levels could cause menstruation and menopausal symptoms that are not the norm. The hormone will help implant a fertilized egg in the uterus, or help maintain pregnancy. Progesterone is not to be taken while pregnant unless otherwise specified.
What else can I help you with?
How does progesterone play a role in a feedback mechanism?
"The corpus luteum synthesizes progesterone, estradiol, and 17-hydroxyprogesterone. The increased progesterone levels affect the thermoregulatory site in the hypothalamus and increase the core body temperature. Negative feedback from the increased release of estradiol and progesterone from the corpus luteum results in decreased serum LH and FSH levels in the luteal phase. If conception has not occurred, FSH levels increase again at the end of the luteal phase as the progesterone and estradiol levels decrease. The decrease in progesterone and estradiol levels results in shedding of the endometrium-i.e., menstruation. LH pulse frequency is high (90 minutes) and of low amplitude in the follicular phase. The pulse frequency and amplitude increase immediately before ovulation".
What directly antagonizes the effect of calcitonin?
Parathyroid hormone (PTH) directly antagonizes the effect of calcitonin. Calcitonin and PTH have opposing effects on bone metabolism, with calcitonin working to decrease calcium levels in the blood, while PTH works to increase calcium levels.
What hormone normally has a more significant effect on blood calcium levels in adults?
parathyroid hormone
What hormones effect menstruation?
The hormones that primarily regulate the menstrual cycle are estrogen and progesterone. Estrogen helps build up the uterine lining, while progesterone maintains it. Changes in the levels of these hormones throughout the menstrual cycle control ovulation and menstruation.
What is the effect of antidiuretic hormone on potassium concentration and excretion?
Antidiuretic hormone (ADH) decreases the amount of sodium in your body and when ever sodium levels go down potassium levels go up (same is true for visa versa) so the amount of Potassium should increase when there is an increase in ADH.
Name the hormone that has an anti pregnant effect?
Progesterone. It does not really have an anti pregnant effect, but makes your body think you are pregnant.

What effect would decreasing levels of estrogen and progesterone have on the female reproductive system?
The endometrium would break down due to low hormone levels.
What happens if you feel like your hormone is over stimulating?
produce side effect
How does progesterone effect the body?
Progesterone levels rise after ovulation to protect the fertilized egg and to prevent the uterine lining from shedding allowing the fertilized ovum to implant in the lining. Progesterone protects the zygote until hCG kicks in after implantation.
When a small amount of one hormone allows a second hormone to have its full effect the phenomenon is called?
When a small amount of one hormone allows a second hormone to have its full effect the phenomenon is called
Why does estrogen need progesterone?
Estrogen in the system without the balancing effect of progesterone has been linked to an increased risk of endometrial cancer
When a hormone opposing the action of another hormone it is called?
antagonistic effect
What is permissive effect dealing with hormones?
Permissive effect when dealing with hormones refers to the effect of one hormone on a second whereby the second can exert its full normal effect that is normally associated with it. For example the effect of cortisol on glucagon's ability to increase blood glucose concentration during fasting is a permissive effect. Another one is the effect of Tri-iodothyronine (T3 active form of thyroid hormone) on epinephrine stimulation of lipolysis.
What directly antagonizes the effect of calcitonin?
Parathyroid hormone (PTH) directly antagonizes the effect of calcitonin. Calcitonin and PTH have opposing effects on bone metabolism, with calcitonin working to decrease calcium levels in the blood, while PTH works to increase calcium levels.
This uterine lining is most responsive to the hormonal effects of estrogen and progesterone?
this urine linning is most responsive to the hormonal effect of strogen and progesterone ovaries.
