Reproductive Hormone Testing
Hormonal evaluation is a key diagnostic tool in gynecology, as it allows assessment of hormonal balance and ovarian function. Through specific blood tests, it provides important information about the menstrual cycle, ovulation, and overall reproductive health.
In cases of difficulty conceiving or before planning a pregnancy, hormonal evaluation helps identify hormonal imbalances early that may affect reproductive function.
What is hormonal evaluation?
Hormonal evaluation is a set of blood tests that assess the function of the hypothalamic-pituitary-ovarian axis, as well as other hormones that affect the menstrual cycle and fertility.
Hormones regulate:
- follicle maturation
- ovulation
- endometrial function
- cycle stability
Even minor disturbances in hormonal balance may affect conception or cause an irregular cycle, delayed periods, or other symptoms.
Hormonal evaluation is not a single test. Rather, it is tailored according to a woman’s age, cycle history, the presence of symptoms, and reproductive planning.
As part of the investigation of female fertility, hormonal evaluation is often combined with ultrasound assessment to provide a comprehensive picture of ovarian function.
Hormonal evaluation: What does it include?
Hormonal evaluation includes specific blood tests that assess ovarian function, ovulation, and overall hormonal balance. The exact panel is individualized, but it usually includes the following hormones:
FSH (Follicle-Stimulating Hormone)
FSH regulates the maturation of ovarian follicles. Elevated levels may indicate reduced ovarian reserve, especially when evaluated in combination with age and AMH.
LH (Luteinizing Hormone)
LH is involved in the process of ovulation. The FSH/LH ratio may provide information about disorders such as polycystic ovary syndrome (PCOS).
Estradiol (E2)
Estradiol is produced by the follicles and reflects their activity. It helps assess ovarian function and the phase of the cycle.
AMH (Anti-Müllerian Hormone)
AMH is an important marker of ovarian reserve. It is not significantly affected by the phase of the cycle and is often evaluated together with AFC measurement.
Prolactin
Elevated prolactin levels may affect ovulation and cause cycle disturbances.
TSH (Thyroid-Stimulating Hormone)
Proper thyroid function is essential for normal reproductive function. Even mild disorders can affect conception.
Progesterone
It is usually measured in the second phase of the cycle and confirms whether ovulation has occurred.
The combination of the above hormones allows a comprehensive assessment of female hormonal function and helps identify possible factors affecting fertility.
Complete hormonal evaluation: When is it needed?
A complete hormonal evaluation is not performed preventively in all women, but it is recommended when there are specific indications or reproductive planning needs.
It is particularly indicated in cases of:
- irregular or absent periods
- heavy or prolonged bleeding
- difficulty conceiving
- recurrent miscarriages
- symptoms such as acne, excessive hair growth, or unexplained weight gain
- preparation for in vitro fertilization (IVF)
As part of the investigation of female fertility, a complete hormonal evaluation helps identify possible disorders that may affect ovulation or ovarian function.
Early diagnosis of hormonal imbalances contributes to proper treatment planning, whether for natural conception efforts or assisted reproduction.
The role of hormonal evaluation in fertility
Hormonal evaluation is a fundamental step in investigating female fertility, as it allows assessment of ovulation, ovarian function, and overall hormonal balance.
Proper hormonal regulation is essential for:
- follicle maturation
- the release of the egg (ovulation)
- preparation of the endometrium for implantation
- maintenance of an early pregnancy
Identifying disorders such as thyroid dysfunction, elevated prolactin, or abnormalities in the FSH/LH ratio may explain difficulty conceiving and guide targeted management.
In the context of in vitro fertilization (IVF), hormonal evaluation is crucial for:
- selecting the appropriate stimulation protocol
- estimating the likely ovarian response
- timing egg retrieval correctly
Combined with ultrasound assessment (AFC), it provides a comprehensive picture of reproductive potential and allows for individualized planning.
Proper interpretation of hormonal tests, combined with ultrasound assessment, allows individualized planning of the next steps based on your own needs and priorities.
Frequently Asked Questions (FAQ)
Most basic hormones are measured during the first days of the cycle (days 2–4 of the period). Progesterone is checked during the second phase of the cycle, while some hormones, such as AMH and TSH, can be tested on any day.
In most cases, no special preparation is required. Some tests may be recommended in the morning, while in specific cases fasting or avoiding certain medications may be advised.
Your doctor will provide clear instructions depending on which hormones are being tested and the reason for the evaluation.
Yes. Hormonal evaluation is a fundamental step before starting in vitro fertilization, as it determines the choice of protocol and helps estimate the likely ovarian response.
Elevated FSH levels combined with low AMH may indicate reduced ovarian reserve or premature ovarian insufficiency. Diagnosis is always made after repeat testing and overall clinical evaluation.
The cost of hormonal evaluation depends on the number and type of tests requested. A basic evaluation includes specific hormones, while a complete hormonal evaluation may be more extensive depending on the reason for the investigation.
