Women who do ivf must have heard of FSH, because when you do treatment your
doctor will ask you to check for six hormones, one of which is FSH. Many female
infertility patients will ask a question: what is FSH (follicle-stimulating
hormone)? Why is there an increase in FSH levels? What does increased levels of
FSH have to do with infertility? What does it have to do with being a test-tube
baby?
What is FSH?
Follicle-stimulating hormone, English abbreviation FSH, is one of the
anterior pituitary basophilic cells secrete hormones, composition of
glycoprotein, luteinizing hormone and collectively gonadotropins, a major role
in follicle granular layer cell proliferation differentiation, promote the whole
ovary grew up, so as to promote the follicle stimulating and role in the
testicles, seminiferous tubule, stimulates the production of sperm. Therefore,
the value of FSH will directly reflect the fertility of both men and women.
Relationship between FSH and infertility
An increase in the value of FSH means that the ovaries have lost their
ovulation function. It is generally believed that if the value of FSH in the
blood exceeds 12, there is the risk of infertility, which also indicates that a
woman has entered pre-menopause. This may raise the question of why elevated
levels of FSH, which is supposed to promote egg maturation, cause infertility in
women. On the one hand, FSH promotes the initial development of egg cells, and
the developing egg cells secrete statins B and estradiol, which inhibit the
production of FSH. This ensures that only one dominant follicle matures in each
cycle. Therefore, under normal physiological cycle conditions, the secretion of
FSH also shows periodic changes. If endocrine disruption occurs, or if a woman's
ovaries lose the ability to release eggs, the development of the egg cell stops,
and the stopped egg cell stimulates the pituitary gland to produce more FSH.
This can lead to increased levels of FSH in the blood.
FSH rise can do ivf?
Before entering the test tube cycle, women need to do a comprehensive
physical examination (including vaginal ultrasound and hormone six tests). Yin
is exceeded check basically is to see the number of follicles of left and right
ovarian of the woman, hormone 6 need a woman to undertake blood test on the 2nd
or 3rd day of menstruation. Women can also have AMH tests to evaluate women's
ovarian function, which has the advantage of high accuracy. The larger the
number, the better (i.e., the higher the AMH number, the better the ovarian
function, but it should be less than 7, if more than 7, there may be a risk of
polycystic ovary syndrome).
If the female FSH hormone level is particularly high, it means that the
lower the ovarian function and egg reserve function of the female, it will have
different degrees of influence on the success rate of ivf. It is generally
recommended that patients receive ivf treatment after FSH value returns to
normal, which will also improve the success rate of ivf.
