Author: Tharb Faisl
Thinking About Your Future? Let’s Talk Fertility.
Fertility isn’t only about trying for a baby today — it’s about understanding your body, identifying any hormone imbalances, and making informed decisions for your future.
Whether you’re 25 and planning ahead, 35 and actively trying, or 42 and exploring your options — a private fertility test in London offers clarity, confidence, and guidance.
At Marylebone Diagnostic Centre, we offer private fertility tests in London with same-day appointments, rapid results, and full discretion.
Fertility by Age: What Changes and Why It Matters
Fertility evolves with age. Here’s what to expect in your 20s, 30s, and 40s — and why a private fertility test in London can help.
👩 In Your 20s:
- Peak natural fertility for most women
- Ideal time to establish a hormone baseline for the future
- Detect early signs of PCOS, thyroid issues, or irregular cycles
👩🦱 In Your 30s:
- Egg count and quality start to decline after age 35
- Hormone fluctuations may occur silently
- Smart time for a fertility MOT, AMH testing, or planning for egg freezing
👩🦳 In Your 40s:
- Natural fertility declines, but pregnancy is still possible
- Testing helps identify support options for conception
- May also reveal early signs of perimenopause affecting hormones
What’s Included in Our Fertility Hormone Tests?
Our private fertility tests in London evaluate core hormone levels to give you a full picture of reproductive health:
| Hormone | What It Tells You |
|---|---|
| FSH & LH | Ovarian reserve, egg development |
| Oestradiol (E2) | Oestrogen & menstrual regulation |
| AMH (Anti-Müllerian Hormone) | Ovarian reserve & egg quantity |
| Progesterone | Confirms ovulation has occurred |
| Prolactin | Can affect ovulation if high |
| TSH & Free T4 | Thyroid function, vital for fertility |
| Vitamin D & B12 | Overall reproductive health markers |
Tests can be booked individually or combined into a customised fertility hormone panel. We’ll help you choose the best timing based on your cycle.
