Fsh stimulates the adrenal cortex to release corticosteroid hormones

In autoimmune gastritis , the immune system attacks the parietal cells leading to hypochlorhydria (low stomach acid secretion). This results in an elevated gastrin level in an attempt to compensate for increased pH in the stomach. Eventually, all the parietal cells are lost and achlorhydria results leading to a loss of negative feedback on gastrin secretion. Plasma gastrin concentration is elevated in virtually all individuals with mucolipidosis type IV (mean 1507 pg/mL; range 400-4100 pg/mL) (normal 0-200 pg/mL) secondary to a constitutive achlorhydria. This finding facilitates the diagnosis of patients with this neurogenetic disorder. [14] Additionally, elevated gastrin levels may be present in chronic gastritis resulting from H pylori infection. [15]

Decreased secretion of anterior and posterior pituitary hormones is known as panhypopituitarism , a serious and sometimes fatal disorder. The term panhypopituitarism is also commonly used when only anterior pituitary hormones are deficient. Patients with panhypopituitarism usually have features of adrenal insufficiency, hypothyroidism , and gonadal failure, along with poor responses to stress. Pituitary vascular insufficiency, autoimmunity , infections, and neoplasms can cause panhypopituitarism. If central diabetes insipidus is present, the lesion generally involves the posterior as well as the anterior pituitary. Isolated deficiencies of one or two pituitary hormones also may occur, often on a heritable basis. Those conditions are rare. Some patients may present with infertility due to LH and FSH deficiency. Proportionate congenital growth failure due to GH deficiency is a predominant type of isolated deficiency.

During the ages of 12-50, the pituitary releases FSH and LH cyclically. FSH stimulates the growth of the ovarian follicle in the ovaries, and also the follicle cells around it to release estrogen.  Estrogen is a feminizing hormone that affects the woman’s body, skin, breasts, bone and causes a slight thickening of endometrial lining. This first 2 weeks is known as the preovulatory phase (or the follicular phase) . Around day 14, after the first 2 weeks, the adenohypophysis starts secreting increasingly-higher amounts of LH and that causes an egg to pop out. Once an egg pops out into the fallopian tube, now a woman could get pregnant and the egg can live only 3-5 days so there’s only a window of 3-5 days where a woman could get pregnant during the cycle. LH is going to be released for 2 weeks, so then we call the ovarian follicle, a corpus luteum, and the ovarian follicles secrete estrogen and progesterone which causes a very strong thickening of the endometrial lining. This is called the luteal (postovulatory phase) because of the release of LH.  About day 28, LH is going to stop being released. The drop in the LH level causes the corpus luteum to degenerate and this drop leads to the shedding of the endometrial lining. It was the increase of progesterone that caused the thickening and now the drop in its level causes the shedding out the birth canal. The first day a woman notices this, is considered the first day of menstruation and the cycle starts all over again.

In persons with evidence of poor ovarian or testicular function, LH is sometimes measured in response to administration of gonadotropin releasing hormone (GnRH) to distinguish between disorders involving the hypothalamus or pituitary gland. GnRH is the hormone produced by the hypothalamus that stimulates the pituitary to release LH and FSH. For this test, a baseline blood sample is drawn and then the person is given an injection of GnRH. Subsequent blood samples are drawn at specified times and the level of LH is measured. This test can help differentiate between a disorder of the pituitary (secondary), when LH will not respond to GnRH, or hypothalamus (tertiary), when LH responds to GnRH. It is also often helpful in the evaluation of precocious or delayed puberty.

Hi gang,
I am on a five minute “lunch” break at 3:53 pm. I am a veterinarian, sooo. This is my first time on this site and I have not even read your blogs yet. I am 36 years old and am just barely engaged at this point. We do indeed want children. I was married prior for three years at 26, no children and then divorce. Okay, so blah,blah. I am so scared we don’t have a shot at getting pregnant. I don’t have regular periods and was told I actually have LOW FSH levels. I have not deeply investigated all options at this time. What do you guys think? Do you think I can get pregnant at 36 to be 37 in Aug? If we can’t concieve we are not opposed to adoption and my future hubby is great about it. But, where does one start? IVF? I have not really found a OBGYN at this point I am sold on, so there is that. But, I am planning a wedding and I am not a kid anymore, so I thought alot about this. If anyone has any info, tips, etc. it would be much appreciated. For some reason I keep dreaming every night that I have had quads, what? No clue why, silly girl. Thanks all! Ash
