Hormones orchestrate nearly every aspect of fertility — from ovulation and egg development to implantation and early pregnancy. A comprehensive reproductive hormone panel identifies imbalances that could be standing between you and conception, giving your specialist the information needed to recommend the most effective treatment.
What Is Hormone Testing?
A reproductive hormone panel measures key fertility hormones — including FSH, LH, oestradiol, AMH, progesterone, prolactin, and thyroid hormones for women, and testosterone, FSH, LH, and prolactin for men. These markers reveal how well the reproductive system is functioning and whether imbalances may be affecting conception.
Timing matters: baseline hormones are ideally drawn on day two or three of the menstrual cycle, while progesterone is tested mid-luteal phase to confirm ovulation. AMH can be tested on any cycle day, making it one of the most convenient ovarian reserve markers. Results guide treatment decisions from lifestyle changes to IVF protocol design.
Common Concerns Hormone Testing Can Address
- Irregular, absent, or unpredictable menstrual cycles
- Difficulty conceiving despite regular unprotected intercourse
- Symptoms of hormonal imbalance such as acne, hair changes, or weight fluctuation
- Suspected polycystic ovary syndrome (PCOS) or thyroid disorder
- Planning IVF, egg freezing, or other fertility treatment and needing baseline values
Are You a Good Candidate?
- Women or men wanting a clear picture of their reproductive hormonal health
- Able to attend a single clinic appointment for a blood draw
- Willing to time the blood test to a specific cycle day if advised
- Open to follow-up treatment or lifestyle changes based on results
Techniques & Options
Reproductive hormone testing is straightforward — it involves a standard blood draw, processed by an accredited laboratory. However, timing matters. Certain hormones fluctuate throughout the menstrual cycle, so your specialist may request that blood is drawn on a specific day to ensure the results are as informative as possible.
Your specialist will select the markers most relevant to your situation, and the full panel is typically drawn from a single blood sample.
Baseline Hormone Panel (Day 2–3)
The core fertility hormone panel is ideally drawn on day 2 or 3 of the menstrual cycle, when hormone levels are at their baseline. This panel typically includes FSH, LH, and oestradiol — the three hormones that reveal how the brain and ovaries are communicating. Elevated FSH or an abnormal FSH-to-LH ratio can indicate diminished ovarian reserve or conditions such as PCOS. Prolactin and thyroid hormones (TSH, free T4) are usually included at the same time, as abnormalities in either can suppress ovulation.
- FSH and LH indicate how hard the body is working to stimulate the ovaries
- Oestradiol provides context for interpreting FSH levels accurately
- Prolactin and thyroid screening catch common, treatable causes of anovulation
AMH & Progesterone Testing
Anti-Müllerian hormone (AMH) can be tested at any point in the menstrual cycle, making it one of the most convenient and reliable ovarian reserve markers. It reflects the pool of remaining follicles and helps predict response to ovarian stimulation. Progesterone is tested in the mid-luteal phase — typically day 21 of a 28-day cycle — to confirm whether ovulation has occurred. A low progesterone level at this point suggests anovulation, which is one of the most common and treatable causes of infertility.
- AMH can be drawn on any cycle day, ideal for flexible scheduling
- Progesterone confirms whether ovulation is occurring each cycle
- Both tests are essential for planning IVF stimulation protocols
Recovery Timeline
Blood Draw
A standard venous blood draw is taken from your arm — the same process as any routine blood test. It takes a few minutes and requires no preparation beyond any fasting instructions your clinic may provide. You can return to normal activities immediately.
Within 24 Hours — Results Available
Most hormone results are available within 24 hours. AMH and some specialised markers may take slightly longer depending on the laboratory. Your clinic will let you know when to expect your results.
Results Consultation
Your fertility specialist will sit down with you to review every result, explain what each marker means, and discuss how they relate to your fertility goals. If any values fall outside the normal range, your specialist will explain the clinical significance and outline the recommended next steps — whether that is lifestyle modification, medication, or further investigation.
After Your Visit
You'll receive a written report summarising all hormone levels, reference ranges, and your specialist's interpretation and recommendations. This document can be shared with your doctor at home or used as the basis for starting treatment in Thailand.
What to Expect
Safety & Risks
Reproductive hormone testing is one of the safest diagnostic procedures in medicine. It involves only a routine blood draw, and there are no medications, sedation, or invasive procedures involved. That said, there are a few considerations to be aware of.
- Minor bruising or soreness at the blood draw site
- Lightheadedness during or after the blood draw (uncommon)
- Anxiety or emotional distress related to receiving results
- Hormone levels fluctuate between cycles, so a single panel provides a snapshot rather than a definitive diagnosis
- Some results may require follow-up testing at a specific point in the cycle
Your specialist will interpret your results in context — taking into account your age, medical history, symptoms, and goals. If any result is borderline or unexpected, they may recommend repeating the test or adding further investigations before drawing conclusions. No treatment decisions are made on the basis of a single hormone level in isolation.
