Before entering the IVF cycle, both men and women have to undergo a series of examinations, in the face of cumbersome examination items, many people do not know the significance of these examinations, especially the six sex hormones, many people wonder why do IVF test sex hormones six? In fact, the six tests of sex hormones before IVF are of great significance for the later formulation of the plan!
The significance of the six tests of sex hormones
1. Follicle-producing hormone (FSH) and luteinizing hormone (LH).
For female patients: judging ovarian failure, follicle-poietin and luteinizing hormone values are higher than normal or even reaching the menopausal level, it is hypergonadotropin amenorrhea, indicating that ovarian function has declined, and there are ovarian lesions, if the value of the two is greater than 3, it indicates polycystic ovary syndrome. By measuring the peak luteinizing hormone, the doctor can know when the woman ovulates and how well she ovulates so that she can decide on the next step of infertility**.
For male patients: to determine whether there are sperm abnormalities, primary ** failure and fine tubule hypoplasia, etc.; Determine whether there is hypogonadism, ** failure and fine tube hypoplasia.
2. Prolactin (PRL).
For female patients: prolactin values over 23 during menstruation3 ng ml is hyperprolactinemia; Patients with amenorrhea, infertility, and menstrual disorders should have prolactin measured regardless of whether lactation is present; Pituitary prolactin tumors should be considered in patients with abnormal prolactin levels; Elevated prolactin levels are also seen in precocious puberty, primary hypothyroidism, premature ovarian failure, poor luteal function, certain drugs such as birth control pills, and excessive estrogen; Decreased prolactin is seen in hypopituitarism, among other things.
For male patients: decreased libido, decreased sperm quality; If you are unable to get an erection during sexual activity, you need to take a prolactin test in time.
3. Progesterone (P).
For female patients: to determine whether ovulation occurs, in addition, blood progesterone levels can also be used to observe the effect of ovulation induction drugs; To judge the function of the corpus luteum, if the level of progesterone in the luteal phase is lower than the physiological value, it is a manifestation of luteal insufficiency; If the test value on the 4th to 5th day of the menstrual period is higher than the physiological value, it is very likely that the corpus luteum is not atrophied.
For male patients: combined with other sex hormones to determine whether there is congenital or chromosomal abnormality due to reproductive dysfunction.
4. Estradiol (E2).
For women: if the estradiol level is consistent with normal cycle changes, indicating normal follicular development, uterine amenorrhea may be considered. If estradiol levels are low, it may also be central amenorrhea, hyperprolactinemia, etc. Determine whether ovulation occurs; Monitor follicular development.
For male patients: to determine whether there is a feminization of men, and to assess whether spermatogenesis is normal.
5. Testosterone (T).
For female patients: useful in assessing the efficacy of polycystic ovary syndrome. In order to evaluate the efficacy, the doctor will instruct when to have a blood draw for a follow-up test during the post-medication process, after which the testosterone value should be lowered.
For male patients: useful to know if ** is functioning properly.
Precautions for the Six Tests of Sex Hormones:
1. Pay attention to the inspection time
It is better to check the six items of sex hormones on the 2nd to 4th day of menstruation, because this period belongs to the early follicle stage, which can reflect the functional status of the ovaries. However, for patients who have not had menstruation for a long time and are anxious to know the results of the examination, the examination can be performed at any time.
2. Pay attention to fasting
In terms of examination, patients are advised to have their blood drawn on an empty stomach to check their sex hormone levels. In order to maintain a relatively stable basic state of hormones in the body, try to take blood tests on an empty stomach.
3. Be cautious about using drugs
Caution must be exercised in the use of drugs, and sex hormones should not be used for at least one month before basic sex hormones, otherwise the reliability of the results will be affected (except for those who need to recheck sex hormones after **).
4. About prolactin
Prolactin secretion is unstable, susceptible to some factors, and has small fluctuations with the menstrual cycle, which is rhythmic in relation to sleep. Blood should be drawn at 8:00 a.m. and 10:00 a.m. to avoid false "hyperprolactinemia" caused by physiologic elevation. Also, do not examine your breasts before your blood is drawn, as your breasts may be irritated and cause prolactin to rise. Stress can also take a toll on this, so make sure you feel relaxed.
