FSH,LH: Gnrh stimulates follicle stimulating hormone & luteinizing hormone which stimulates the ovary to produce estrogen and Progesterone which stimulates ovulation which causes increased Progesterone which causes secretory endometrium which prepares the endometrium to allow implantation of a fertilized egg. If no fertilized egg, Progesterone falls which stimulates gnrh to again rise & the cycle repeats. ...Read more
Interesting question: Nocturnal secretion of melatonin has been shown to affect secretion of prolactin. To my knowledge melatonin can exacerbate mild hyperprolactinemia. The relationship between Progesterone and prolactin i think is more unclear. We know thatprogesterone can affect prolactin in various ways. I'm curious to know in what context you would like to know the answer to this question? ...Read more
High follicle-stimulating hormone (fsh) and luteinizing hormone (lh)--what are normal levels at ovulation?
Inhibitory: Hi. The main hypothalamic influence on prolactin (PRL) secretion is inhibitory, not stimulatory. Dopamine from hypothalamic neurons is inhibitory on anterior pituitary lactotroph cells. There is a stimulatory effect in a fairly sizable fraction of patients from hypothalamic TRH, which is elevated in hypothyroidism. But there is no primary hypothalamic stimulator of PRL secretion. ...Read more
Probably: Normal ranges can vary from lab to lab, so the 1st step would be to compare your results to the reference range, usually listed in parentheses such as (1.5 - 10). For hormone tests, however, results have to be interpreted in the context of what is happening clinically. Expected values for someone who is pregnant, or on birth control pills, or who should be ovulating at the time could all differ. ...Read more
Yes: After taking Clomid (clomiphene) fsh levels may rise - this is the basis of the Clomid (clomiphene) challenge test (cct, also known as the ccct) which is a test of ovarian reserve or 'egg supply'. For this test you get an fsh level and Estradiol blood test on day 2 or 3, take 100 mg or two pills of Clomid (clomiphene) a day from days 5 to 9, then repeat the fsh test on day 10. Clomid (clomiphene) does not affect day 2 or 3 fsh levels though. ...Read more
Microprolactinoma- mod. Elevated prolactin, pituitary stalk deviated left, extremely low t : cabergoline normalized prolactin, yet t remained low?
Good question: Gnrh would seem by its name to help release gonadotropin. And if used in a certain fashion it could cause the release of gonadotropins (lh, fsh). However when given in a shot and having a sustained effect on the pituitary, it actually suppresses the release of lh and fsh. And this aspect of the medication can be used to help in many situations. ...Read more
Interesting question: I have not found any publications specifically studying this question. Antipsychotics and Prozac (fluoxetine) can affect prolactin, potentially changing sex hormone levels. This may or may not relate to shbg levels, though. I did find one small (20 patients) study online concerning low testosterone levels and antidepressant-induced sexual dysfunction: http://tinyurl.Com/mk84cfr further research needed. ...Read more
Is PCOS or non classic CAH?FSH/LH are 1:3 ratio Testosteron Androstenedion 17Oh Progesteron are high Cortizol DHEA-S SHBG PROLACTIN Normal ACTH low
ACTH stimulation: If you have features of both problems, the male hormone levels and menstrual irregularities and infertility are the hallmarks of a diagnosis of PCOS. What does your Endo or Gyne/Endo say about this ? Ask them for answers, which may include an ACTH stim test to see how your pituitary axis is functioning to start with, followed by more adrenal function testing... ...Read more
