FERTILITY CAPSULE III (FSH, LH, PROLACTIN, E2, DHEAS, PROGESTERONE, TSH)

Fertility Capsule III is a comprehensive blood-test panel that measures Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), prolactin, estradiol (E2), Dehydroepiandrosterone Sulfate (DHEAS), progesterone and Thyroid-Stimulating Hormone (TSH). These hormones provide information about ovarian function, follicle development, ovulation, adrenal androgen production, pituitary function and thyroid-related factors that may affect reproductive health.

FSH, LH and estradiol help assess communication between the pituitary gland and ovaries. Progesterone testing may support assessment of whether ovulation has recently occurred when collected at the correct time. Prolactin and thyroid abnormalities may interfere with menstrual regularity and ovulation. DHEAS helps evaluate adrenal androgen production, particularly when symptoms such as excess facial hair, acne or irregular periods are present.

This panel supports hormonal fertility evaluation but cannot independently confirm overall fertility, assess ovarian reserve completely, determine egg quality, examine the fallopian tubes or evaluate semen quality. Test timing is especially important because FSH, LH, estradiol and progesterone change throughout the menstrual cycle. Results must be interpreted with the collection day, symptoms, medicines and other fertility investigations.

Benefits of the Test

• Measures seven hormones associated with reproductive and endocrine health.
• Supports evaluation of ovarian and pituitary hormone function.
• Helps assess irregular or absent menstrual periods.
• May support evaluation of ovulation when progesterone is collected at the correct time.
• Assesses prolactin-related factors that may interfere with ovulation.
• Checks TSH for thyroid-related reproductive abnormalities.
• Measures DHEAS to assess adrenal androgen production.
• May support evaluation of PCOS and androgen-excess symptoms.
• Provides multiple related hormone results from one blood collection.

Why Doctors Recommend This Test

A doctor may recommend Fertility Capsule III when a woman has difficulty becoming pregnant, irregular menstrual periods, absent periods or symptoms suggesting a reproductive hormone imbalance. It may also be requested when the doctor wants to evaluate whether ovulation is occurring or investigate possible pituitary, thyroid or adrenal factors.

FSH is produced by the pituitary gland and stimulates ovarian follicles to grow. LH contributes to final follicle development and helps trigger ovulation. Estradiol is produced mainly by developing ovarian follicles. These hormones vary during the menstrual cycle and are interpreted according to the collection day and their relationship with one another.

Progesterone is produced mainly by the corpus luteum after ovulation. A properly timed progesterone measurement may provide evidence that ovulation has recently occurred. The test is often collected approximately seven days before the expected next menstrual period rather than automatically on cycle day 21 for every woman. One progesterone result cannot assess egg quality or guarantee that conception occurred.

Prolactin is produced by the pituitary gland. A persistently elevated prolactin concentration outside pregnancy or breastfeeding may disrupt reproductive hormone signalling and contribute to irregular periods, absent periods or impaired ovulation. Temporary increases may occur because of sleep, emotional stress, exercise and certain medicines.

DHEAS is an androgen produced mainly by the adrenal glands. Increased levels may occur with PCOS, adrenal disorders or certain medicine and supplement use. Doctors may request DHEAS when a woman has excess facial or body hair, persistent acne, scalp hair thinning, irregular periods or other signs of androgen excess.

TSH regulates thyroid-hormone production. Both underactive and overactive thyroid function may affect menstrual cycles, ovulation and fertility. An abnormal TSH result may require additional tests such as free T4 and thyroid antibodies to clarify thyroid function and identify the cause.

Preparation Before Test

A venous blood sample is collected, usually from a vein in the arm. Fasting is not always required solely for this panel. However, morning collection or fasting may be advised depending on the clinical purpose and other investigations ordered. Follow the instructions provided by the doctor or Focus Diagnostics.

Inform the doctor and laboratory about the first day of the last menstrual period, usual cycle length and whether cycles are regular. FSH, LH and estradiol are often collected during the early follicular phase, commonly around cycle days 2 to 5, when baseline assessment is required.

Progesterone requires different timing. It is commonly measured during the mid-luteal phase, approximately seven days after ovulation or seven days before the expected next period. For a regular 28-day cycle, this may be near day 21, but day 21 is not appropriate for every cycle length. The doctor should specify whether all tests should be collected together or whether progesterone requires a separate sample.

Prolactin may rise temporarily because of sleep, anxiety, pain, strenuous exercise, sexual activity or nipple stimulation. The doctor may recommend morning collection a few hours after waking and a short period of quiet rest before the sample is taken.

DHEAS has less daily variation than some other adrenal hormones, but patients should still follow the requested collection timing. Inform the doctor about DHEA supplements, steroids and hormonal medicines because they may influence the result.

Provide a complete list of prescribed medicines, non-prescription medicines, vitamins and supplements. Fertility medicines, hormonal contraception, estrogen, progesterone, thyroid medicines, antipsychotics, antidepressants, anti-nausea medicines, steroids and biotin may affect one or more test results or laboratory assays.

Do not stop any medicine without medical advice. Also report pregnancy, breastfeeding, thyroid disease, pituitary disease, PCOS, adrenal disorders, ovarian surgery, recent illness, cancer treatment and major changes in body weight.

Normal Reporting Time

Fertility Capsule III is generally reported within 24 to 48 hours after the laboratory receives an acceptable sample. The turnaround time depends on the testing schedule for all seven hormone assays and whether progesterone is collected separately according to the menstrual-cycle phase.

Reporting may take longer when a result requires repeat analysis, dilution, quality verification or correlation with another sample. Patients requiring results before a fertility consultation or treatment cycle should confirm the expected turnaround time with the collection centre.

Who Should Take This Test?

This panel may be recommended for women experiencing difficulty becoming pregnant, irregular or absent periods, suspected ovulatory dysfunction or symptoms indicating reproductive hormone imbalance. It may also be considered before or during selected fertility investigations and treatments.

Women with symptoms of androgen excess, including persistent acne, increased facial or body hair, scalp hair thinning or menstrual irregularity, may require DHEAS and related hormone testing. These findings may occur with PCOS, but this panel alone cannot diagnose PCOS.

Women with unexpected nipple discharge, menstrual disruption or suspected high prolactin may also be advised to undergo testing. Pregnancy, medicines and thyroid dysfunction must be considered when interpreting prolactin.

The panel may assist women with possible thyroid-related fertility problems or symptoms such as unexplained weight changes, tiredness, temperature intolerance or menstrual changes. An abnormal TSH result generally requires further clinical assessment.

This package is primarily structured for female hormonal evaluation. Male infertility assessment usually requires semen analysis and may include testosterone and other selected hormones. Because testosterone is not included in Fertility Capsule III, this package is not a complete male fertility hormone profile.

Understanding the Hormones

FSH: FSH stimulates the development of ovarian follicles. An increased early-cycle FSH result may be associated with reduced ovarian response or ovarian insufficiency. A low result may occur with pituitary or hypothalamic dysfunction. Interpretation requires the menstrual-cycle day and estradiol concentration.

LH: LH helps trigger ovulation and supports the corpus luteum after ovulation. Its concentration changes throughout the cycle and rises during the pre-ovulatory surge. Abnormal patterns may occur with PCOS, ovarian dysfunction or pituitary and hypothalamic disorders.

Prolactin: Prolactin supports milk production. Persistently elevated levels may interfere with menstrual cycles and ovulation. Possible causes include pregnancy, breastfeeding, hypothyroidism, certain medicines and pituitary conditions. Mild elevations may require repeat testing.

Estradiol: Estradiol is a major estrogen produced primarily by developing follicles. It supports reproductive-organ function and growth of the uterine lining. Its concentration changes significantly across the cycle, making correct timing essential.

DHEAS: DHEAS is an androgen made mainly by the adrenal glands. Increased concentrations may support investigation of adrenal androgen excess. The result is interpreted with symptoms and, when required, testosterone, 17-hydroxyprogesterone and other investigations.

Progesterone: Progesterone increases after ovulation and prepares the uterine lining for possible pregnancy. A mid-luteal result may provide evidence of recent ovulation, but one measurement cannot evaluate every aspect of luteal function or pregnancy potential.

TSH: TSH controls thyroid-hormone production. Increased or decreased TSH may suggest altered thyroid function, but free T4 and other tests may be required to establish the type and cause.

Detailed Information

Female reproductive function depends on coordinated communication between the hypothalamus, pituitary gland, ovaries, adrenal glands and thyroid gland. FSH and LH act on the ovaries, which produce estradiol and progesterone. Prolactin and thyroid function can influence this reproductive pathway, while adrenal androgens such as DHEAS may affect menstrual and ovulatory function when abnormal.

Hormone-test timing is one of the most important limitations of this package. Baseline FSH, LH and E2 are often measured early in the cycle, while progesterone is generally most informative during the mid-luteal phase. Collecting every hormone on one day may not answer both clinical questions. Patients should follow the doctor's collection plan rather than selecting a day without guidance.

Reference intervals vary according to age, menstrual-cycle phase, pregnancy status, medicines and laboratory method. Patients should use the reference ranges printed on their Focus Diagnostics report rather than comparing the values with another laboratory or an online fertility chart.

A normal panel does not exclude infertility. Additional female fertility investigations may include AMH for ovarian-reserve assessment, pelvic ultrasound, antral follicle count, ovulation tracking, tubal-patency testing and examination of the uterus. The male partner may require semen analysis because fertility difficulties can involve either or both partners.

An abnormal result does not automatically indicate permanent infertility. Hormonal changes may be temporary, medicine-related or manageable. Repeat or additional testing may be required before establishing a diagnosis. Fertility medicines, thyroid treatment or hormonal supplements should not be started or changed solely on the basis of this panel without professional medical advice.
