What allows Follicle-stimulating hormone and Luteinizing hormone levels to increase again?
Once GnRH levels increase, FSH and LH levels will increase. During pregnancy, GnRH is not required which is responsible for the lack or absence of FSH and LH production. Prolactin can also decrease GnRH production which again will decrease FSH and LH. Luteinizing hormone (LH) levels can also be affected by another hormone called melatonin, which is regulated by the hypothalamus and released by the pineal gland in repsonse to the amount of broad-spectrum light that enters the eyes.
What else can I help you with?
If your luteinizing hormone is positive does that mean you are pregnant?
No Luteinizing hormone is secreted as part of the monthly menstrual cycle. It triggers ovulation and allows retention of the corpus luteum. The hormone secreted during pregnancy is called human chorionic gonadotropin (hCG).
When a small amount of the one hormone allows a second hormone to have its full effect the phenomenon is called?

What hormone allows kidneys to regulate?
ADH is the hormone. It is secreted by pituitary.

Where does corpus luteum develop?
The corpus luteum is formed from the ovary. The pituitary gland increases its production of the second hormone, luteinizing hormone (LH). This second hormone allows the mature egg to rupture from the ovary (called ovulation) and enter into the uterine tube. The postovulatory phase has begun. LH also encourages the formation of a "scar" within the ovary. This "scar" is called the corpus luteum, and it produces the hormone progesterone.
Which hormone is secreted by the pituitary glands and increase the permeability of the collecting tube to water?
Antidiuretic hormone (ADH), also known as vasopressin, is the hormone secreted by the pituitary gland that increases the permeability of the collecting tubule to water. This allows the body to reabsorb more water and concentrate the urine, helping maintain water balance in the body.
What is required for The secretion of each of the hormones from the anterior pituitary?
The anterior pituitary produces luteinizing hormone and follicle stimulating hormone. Both are gonadotropins.
Is a hormone that allows for milk expulsion and the onset of labor?
Prolactin
What hormone is released into the blood when the body loses fluid?
When your body loses fluids it alters your blood pressure sending signals to your brain telling it that your BP is too low. This sends off signals to your body to try and compensate. ADH (anti-diuretic hormone) is released and prevents fluid to be excreted by the kidneys into your urine. This raises the blood pressure back up by increasing the water within it. This doesn't increase your RBCs or platelets but it just allows your blood volume to remain at a relatively normal level. It's the anti-diuretic hormone.
In circumstances where the body requires prolonged or increased levels of a hormone the DNA of target cells will specify the synthesis of more receptors on the surface of the cells of the target organ?
Yes, this process is known as upregulation. When the body needs higher levels of a hormone for an extended period, the target cells can increase the number of receptors on their surface through gene expression to enhance sensitivity and response to the hormone. This allows the cells to better respond to the increased hormone levels to maintain homeostasis.
What hormone is important in diabetes insipidus?
Diabetes insipidus is caused by a lack of anti-diuretic hormone. This hormone is usually responsible for creating water channels in the collecting duct of the kidney, which allows urine to be concentrated.
What is the hormone antagonists of pth?
Calcitonin is an antagonist to PTH C cells increase calcitonin secretion due to high blood Ca levels PTH is secreted due to decrease in Ca level in blood Calcitonin allows osteoclasts to increase bone resorption when blood Ca level decreases.
