    Hormon Analysis

    In order to assess a woman’s reproductive function, all patients at Dr.Invitro  complete what is known as day 3 testing. Day 3 testing consists of bloodwork and an ultrasound that is completed on the third day of a woman’s menstrual cycle.

    The blood drawn is used to measure various hormone levels that help determine if you are ovulating as well as your ovarian reserve (or egg supply). Day 3 hormone testing measures:

    • E2 (estrogren): E2 is the main female reproductive hormone that is secreted from the ovary and stimulates follicle growth as well as prepares the uterine lining for implantation.
    • FSH (follicle-stimulating hormone): FSH is released from the brain and stimulates the ovary to mature an egg.
    • LH (luteinizing hormone): LH is integral in the final maturation and release of a mature follicle.
    • AMH (anti-Müllerian hormone): AMH indicates the size of ovarian reserve. AMH is secreted by the small antral follicles found in the ovaries at the start of the menstrual cycle.
    • Other: Additional hormone tests may be performed to assess general health and cycle regularity.

    Cycle day 2 or 3

    A woman’s menstrual cycle is measured from the first day of her period (blood flow, not spotting), so Cycle Day 3 is the third day of her period. When a woman is undergoing a fertility workup, Cycle Day 3 is the day she has blood work performed to check the levels of three important levels: follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2).

    FSH is secreted by the pituitary gland. It stimulates the production of estradiol (estrogen) and eggs (oocytes) during the first half of the menstrual cycle. The eggs begin to grow in their individual fluid sacs, or follicles, which is the first step in the ovulation process. High levels of FSH are an indication of poor ovarian reserves; in other words, the quality and quantity of eggs are low. This does not necessarily mean that pregnancy is impossible, but it may be more difficult to achieve.

    The FSH blood test is used to help diagnose problems with sexual development, menstruation, and fertility. It can be used to diagnose or evaluate polycystic ovary disease, ovarian cysts, irregular vaginal bleeding and infertility.

    The LH blood test measures the amount of luteinizing hormone, which is also secreted by the pituitary gland. In women, LH levels rise at mid-cycle; within 24 to 36 hours, ovulation occurs. Higher-than-normal levels of LH indicate several disorders, including ovarian failure and polycystic ovary disease.

    Estradiol is the most important form of estrogen. It is primarily made in and released from the ovaries, adrenal cortex and the placenta, and it is responsible for the growth of the breasts, outer genitals, uterus, fallopian tubes and vagina.

    Prolactin Level Test

    Understanding prolactin and the prolactin test

    Prolactin is produced by the pituitary gland in the brain. It’s also known as PRL or lactogenic hormone. Prolactin is mainly used to help women produce milk after childbirth.

    It’s important for both male and female reproductive health. The specific function of prolactin in men is not well-known. However, prolactin levels have been used to measure sexual satisfaction in both men and women trusted Source. A prolactin level test can reveal other issues caused by the hormone.

    Why is the prolactin test done?

    Women

    Women with prolactinoma symptoms may need the test. Prolactinoma is a noncancerous tumor on the pituitary gland that produces high levels of prolactin.

    Symptoms of prolactinoma in women include:

    • unexplained headaches
    • visual impairment
    • galactorrhea, or lactation outside of childbirth or nursing
    • pain or discomfort during sex
    • abnormal growth of body and facial hair
    • abnormal acne

    The test is usually performed on people with prolactinoma to keep track of the tumor’s response to treatment.

    In addition, the prolactin test may be needed if you’re having fertility problems or irregular periods. The test can also rule out other pituitary gland or hypothalamus problems.

    Men

    Men may need the test if they display symptoms of prolactinoma. Symptoms of prolactinoma in men include:

    • unexplained headaches
    • visual impairment
    • reduced sex drive or fertility problems
    • erectile dysfunction
    • abnormal lack of body and facial hair

    The test may also be used to:

    • investigate testicular dysfunction or erectile dysfunction
    • rule out problems with the pituitary gland or hypothalamus

    Why does the thyroid matter in fertility?

    The thyroid is an endocrine gland that produces hormones that regulate the growth and function of other bodily systems. It is crucial for regulating metabolism, energy production, oxygen utilization, and hormone levels.

    Thyroid hormones are produced by everybody and play an important part in the growth. As such they are critical in pregnancy. If the thyroid is over or underactive, this can affect ovulation regulation and reduce fertility. Many women suffer from thyroid dysfunction; around 25% of women in their lifetime, which is around 4x more women than men. Graves disease is the most common thyroid dysfunction, affecting 1% of the population. These conditions are important infertility, because thyroid hormones are important in regulating ovulation, preventing miscarriage, and aiding fetal brain development.

    Thyroid hormone levels

    Thyroid hormone levels can be measured by a simple thyroid-stimulating hormone (TSH) blood test. It is important that TSH is at an optimal level, as it affects ovulation; up to 5% of women struggling to conceive have abnormal thyroid hormone levels.

    What is an anti-müllerian hormone (AMH) test?

    This test measures the level of anti-müllerian hormone (AMH) in the blood. AMH is made in the reproductive tissues of both males and females. The role of AMH and whether levels normally depend on your age and gender.

    AMH plays an important role in the development of sex organs in an unborn baby. During the first weeks of pregnancy, a baby will start developing reproductive organs. The baby will already have the genes to become either a male (XY genes) or a female (XX genes).

    If the baby has male (XY) genes, high levels of AMH are made, along with other male hormones. This prevents the development of female organs and promotes the formation of male organs. If there is not enough AMH to stop the development of female organs, organs of both sexes may form. When this happens, a baby’s genitals may not be clearly identified as male or female. This is known as ambiguous genitalia. Another name for this condition is intersex.

    If the unborn baby has female (XX) genes small amounts of AMH are made. This allows for the development of female reproductive organs. AMH has a different role for females after puberty. At that time, the ovaries (glands that make egg cells) begin making AMH. The more egg cells there are, the higher the level of AMH.

    In women, AMH levels can provide information about fertility, the ability to get pregnant. The test may also be used to help diagnose menstrual disorders or to monitor the health of women with certain types of ovarian cancer.

    Other names: AMH hormone test, müllerian-inhibiting hormone, MIH, müllerian inhibiting factor, MIF, müllerian-inhibiting substance, MIS

    Glucose screening tests during pregnancy

    A glucose screening test is a routine test during pregnancy that checks a pregnant woman’s blood glucose (sugar) level.

    Gestational diabetes is high blood sugar (diabetes) that starts or is found during pregnancy.

    How the Test is Performed

    TWO-STEP TESTING

    During the first step, you will have a glucose screening test:

    • You DO NOT need to prepare or change your diet in any way.
    • You will be asked to drink a liquid that contains glucose.
    • Your blood will be drawn 1 hour after you drink the glucose solution to check your blood glucose level.

    If your blood glucose from the first step is too high, you will need to come back for a 3-hour glucose tolerance test. For this test:

    • DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.)
    • You will be asked to drink a liquid that contains glucose, 100 grams (g) .
    • You will have blood drawn before you drink the liquid, and again 3 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked.
    • Allow at least 3 hours for this test.

    ONE-STEP TESTING

    You need to go to the lab one time for a 2-hour glucose tolerance test. For this test:

    • DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.)
    • You will be asked to drink a liquid that contains glucose (75 g).
    • You will have blood drawn before you drink the liquid, and again 2 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked.
    • Allow at least 2 hours for this test.
