Understanding AMH, FSH & LH Tests for Better Pregnancy Planning
When it comes to planning pregnancy, many women assume that their chronological (biological) age directly reflects their ability to conceive. However, in fertility medicine, what matters more is your fertility age—which can be very different from the number on your birth certificate.
At KIC Bengaluru (Kiran Infertility Centre), we often see women in their mid-20s or early 30s surprised to learn that their fertility age may be higher—or sometimes lower—than expected. Understanding this difference early can help you make informed decisions about pregnancy and fertility preservation.
What Is Biological Age?
Biological age simply refers to your actual age in years.
For example:
- If you are born in 1998, your biological age in 2026 is 28.
- While biological age is important for general health, it does not always reflect the health of your ovaries or eggs.
What Is Fertility Age?
Fertility age reflects:
- The number of eggs remaining in your ovaries (ovarian reserve)
- The quality of those eggs
- How well your ovaries respond to hormonal signals
Two women of the same biological age can have very different fertility ages due to genetics, lifestyle, medical conditions, or past treatments.
Why Fertility Age Matters More Than You Think
Eggs are not produced throughout life. Women are born with a fixed number of eggs, and this number steadily declines with age.
- Egg quantity reduces over time
- Egg quality declines faster after the age of 30–35
- Risk of infertility, miscarriage, and chromosomal issues increases with declining egg quality
This is why fertility specialists focus on ovarian reserve tests rather than age alone.
Key Tests to Assess Fertility Age at KIC Bengaluru
1. AMH Test (Anti-Müllerian Hormone)
The AMH blood test is one of the most reliable indicators of ovarian reserve.
What AMH tells us:
- Approximate number of eggs remaining
- Helps estimate fertility age
- Predicts response to fertility treatments like IVF
Important facts about AMH:
- Can be done on any day of the menstrual cycle
- AMH naturally declines with age
- Low AMH does not mean pregnancy is impossible—but it signals urgency
2. FSH Test (Follicle Stimulating Hormone)
The FSH test is usually done on Day 2 or Day 3 of the menstrual cycle.
What FSH indicates:
- How hard the brain is working to stimulate the ovaries
- Higher FSH levels suggest reduced ovarian reserve
Key insight:
- Normal FSH does not always mean good egg quality
- High FSH is often associated with advanced fertility age
FSH is best interpreted along with AMH and ultrasound findings.
3. LH Test (Luteinizing Hormone)
The LH test, also done on Day 2/3, helps assess hormonal balance and ovulation patterns.
Why LH matters:
- High LH compared to FSH may indicate PCOS
- An imbalanced LH can affect ovulation and egg release
- Helps plan fertility treatments accurately
At KIC Bengaluru, LH levels are evaluated in combination with FSH to understand overall reproductive health.
Follicular Scan: Seeing Your Egg Reserve
A transvaginal follicular scan counts antral follicles in the ovaries.
This scan helps to:
- Visually assess egg reserve
- Support AMH and hormone test results
- Guide treatment planning
This scan, along with blood tests, gives a complete picture of fertility age.
Common Myths About Fertility Age
❌ “I’m young, so I don’t need fertility testing”
❌ “Regular periods mean my fertility is perfect”
❌ “Low AMH means I can never get pregnant”
✅ The truth: Early testing provides clarity, not fear.
Why Early Fertility Testing Is Important
Early fertility assessment helps:
- Plan pregnancy at the right time
- Decide on fertility preservation (egg freezing)
- Avoid last-minute stress and rushed decisions
- Improve success rates of fertility treatments
At Kiran Infertility Centre, Bengaluru, early evaluation is encouraged even if you are not planning pregnancy immediately.
Who Should Consider Fertility Testing?
You should consider fertility tests if:
- You are above 25–30 and delaying pregnancy
- You have PCOS, endometriosis, or thyroid issues
- You have irregular periods
- You have a family history of early menopause
- You are planning marriage or pregnancy later in life
