For most women, age best predicts the chance of conception each month. However, despite having regular menstrual cycles and normal periods, about 10% of women lose their fertility sooner than expected. These women should think about having a family in their 20s or very early 30s.
There are several tests which help predict whether a woman may have a faster biological clock one of these is the Anti-Müllerian Hormone (AMH) test. This test helps to estimate what is called ovarian reserve by measuring the number of follicles developing in the ovary at a particular time. Once the test is complete, we compare the results with those of other woman of the same age.
AMH is a hormone made by small follicles as they grow in the ovaries. This test is more convenient and less expensive than alternative tests like Egg Check, because it uses a simple blood test rather than ultrasound scanning, and can be done at any time in the menstrual cycle. It is available from all Fertility Associates clinics. An AMH test can pick up who might lose their fertility more quickly but it does not show who is more fertile than average. AMH does not predict ovarian reserve in women older than 40 or those with Polycystic Ovaries (PCO).
Super excited for you!
