Two check points in time

1. Menstrual 2nd and 3rd days (menstrual) hormone testing: focus on egg nest reserves and basic endocrine levels

2. Menstrual 12th and 13th days (ovulation period) hormone testing: focus on the growth and maturation of follicles and ovulation

Usually before the IVF cycle we ask women to check for six hormones (must be reproductive) within 2-3 days of menstruation to assess fertility and success rates.

Folly-producing hormone FSH

A glycoprotein hormone secreted by alkaline cells in the pituitary front, whose main function is to promote the development and maturation of the ovaries’ follicles.

Menstrual examination: The basic FSH above 10 indicates poor ovarian reserve, combined with AMH level and female age can be estimated egg reserve spree. FSH is highly common in ovarian premature aging, ovarian insensitivity syndrome, primary amenorrhea, etc. FSH above 40 mIU/ml is not effective for ovulation drugs such as cromion.

Projumite-generating lH

A glycoprotein hormone secreted by alkaline cells in the pituitary front, which mainly promotes ovulation, forms the progesterone and secretes progesterone under the synergy of FSH.

Menstrual check: LH below 5 mIU/ml suggests insufficient function of gonadotropins: High FSH if high LH is added, there are significant signs of ovarian failure. LH/FSH 3 is one of the basis for diagnosing polycystic ovary syndrome.

Ovulation period: LH peak to judge ovulation – see for pre-ovulation LH peak and determine whether close to/ or ovulation, ovulation test paper is LH test paper.

estradiol E2

Secreted by the ovaries’ follicles, the main function is to promote the endometrium to change into a hyperphused period and promote the development of a woman’s second sexual characteristics.

Menstrual: Base E2 is normal below 50 pg/ml. Because E2 and FSH are negative feedback, even if the underlying FSH is less than 10, but E2 above 50 pg/ml is also likely to have poor ovarian reserve.

Ovulation period: E2 high and low to determine the quality of follicles and maturation time. In general, a mature follicle has more than 150 estrogens as support, to determine the time to take the egg and inject HCG follicles to cook the needle. When the follicles size reaches more than 18, but estrogen is less than 150, it is considered to be low estrogen, the possibility of a bubble or poor egg quality.

Prol prL

Secreted by one of the preocetic eophilic cells of the pituitary gland, lactation nourishing cells are a pure lying hormone whose main function is to promote breast growth, breast production and milk removal.

Menstrual period: Prolactin is higher than 17.6 ng/ml for hyperlactinemia: too much prolactin inhibits the secretion of FSH and LH, inhibits ovarian function, inhibits ovulation.


Secreted by the ovary’s progesterone, the main function is to promote the endometrium from the proliferation period to the secretion period.

Menstrual period: Blood P concentration is 0-4.8 nmol/L in preoction, 7.6-97.6 nmol/L in late ovulation. Blood P value is low in the late ovulation, seen in yellow function is incomplete, ovulation type uterine dysfunction bleeding.


50% of testosterone in women is converted by peripheral oxycodone, about 25% of the adrenal cortex secretes, and only 25% from the ovaries. The main function is to promote the development of female genitalia. There is an tagon on estrogen and has a certain effect on systemic metabolism.

Menstrual period: Female plasma testosterone levels at 0.7-2.1 nmol/L, with polycystic ovary syndrome, blood T value supplias are also increased, hairy, accompanied by acne, semolation and hair loss.

FSH and LH indicators in hormone six

In the normal menstrual cycle, the early follicles (menstrual 2 to 3 days) blood FSH, LH are maintained at a low level, rapid increase before ovulation, LH up to 3 to 8 times the base value, up to 160 IU/L very higher. FSH only has about 2 times the base value, very little, 30 IU/L, after ovulation FSH, LH quickly returned to follicle level. Monitoring the FSH and LH levels of the early stage of follicles can determine the function of the adenoid axis. FSH is more valuable than LH in determining ovarian potential.

1. Ovarian failure: the basic FSH 40 IU/L, LH elevation or 40 IU/L, for hypergonoid hormone (Gn) amenorrhea, i.e. ovarian failure;

2, ovary reserve dysfunction (DOR):the basic FSH/LH 2 to 3.6 prompt DOR (FSH can be in the normal range), is the early manifestation softening of ovarian dysfunction, often prompt patients to superooovulation (COH) poor response, should be timely adjusted COHGn program and dose to improve the response of the ovaries, to obtain the ideal pregnancy rate. Because the increase in FSH/LH only reflects the DOR, rather than the reduced ability to conceive, the ideal pregnancy rate can still be obtained once ovulation is obtained.

3, the basic FSH and LH are both low Gn amenorrhea, indicating hypothalamus or dysleukoid function, and the difference between the two need to use gonadotropin release hormone (GnRH) test.

4, the foundation FSH 12 IU/L, the next cycle review, such as continuous 12 IU/L prompt DOR.

5, polycystic ovary syndrome (PCOS):the base LH/FSH 2 to 3, can be used as the main indicator of diagnosis of PCOS (basic LH level sgt; 10 IU/L is elevated, or LH maintains normal levels, and the relatively low level of the base FSH, the formation of LH and FSH ratio increase).

6, check 2 basic FSH 20 IU/L, can be considered to be the ovary premature aging hidden period, indicating that 1 year after may be amenorrhea.
