What is the FSH blood test?

FSH. Fsh is an indirect marker of ovarian reserve, ie the ability to generate more eggs with fertility treatment. It is not a very effective marker of egg quality. So the implication of a high or borderline value depends on your age, and whether you are attempting pregnancy on your own or resorting to ivf. Most fertility specialists prefer amh testing as it is more consistent and can be done any time.
Egg Reserve Marker. Fsh is the brains hormone to help recruit your one egg for the month. A day 2 -3 FSH is the feedback from the ovary to say, I am not pregnant this month. If the ovary is not working properly (ie diminished ovarian reserve), then the FSH by the brain willl not lower and be elevated one one gets their period. Thus you a low level. A new test called amh measures how many eggs one has left.
FSH. Fsh is follicle stimulating hormone, which comes from the pituitary gland and stimulates the ovarian follicles to grow. The ovary hormones estrogen & inhibin feedback and keep FSH in balance. Fsh rises as you age and run out of eggs. High levels of FSH indicate low egg quality regardless of your age. We use FSH to help guage your fertility potential. No test is perfect though. See your doc.

Take 200 mg daily prometrium took blood test cycle day 21 progesterone. 9 estrogen 40 fsh 7.2 lh 3.9 progesterone still low?

FSH: age 50. 200 mg. of prometrium will not raise your progesterone levels above what is noted. An FSH of 7.2 is not menopausal, and indicates that you are producing significant levels of estrogen, just not ovulating, which makes the progesterone level only produced by the prometrium. This is normal for age 50, and your ovaries are still active and productive of estrogen. Read more...

My husband was diagnosed of azoospermia. His blood test result reveals thus: FSH 23.4, LH 11.4 and prolactin 12.5 (all in miu/ml). Can he be treated?

Testes problem. Hi. Those data demonstrate primary hypogonadism, that is the defect lies in the testicles, not the pituitary. Is his testosterone low? That LH would predict so. That FSH should be driving spermatogenesis quite robustly, but it can't because of a testicular defect (a number are possible: genetic, toxic, traumatic, etc). He needs to see a fertility doc, and probably have a testicular biopsy. Read more...
