Mullerian Inhibiting Substance (AMH) in Dehradun

What is a Mullerian Inhibiting Substance (AMH)?

Anti-Mullerian Hormone is produced by the small developing follicles in the ovaries, so the amount circulating in blood is proportional to how many of those follicles remain. That makes it the best available blood marker of ovarian reserve, meaning the size of the remaining egg supply. Its practical advantage over older tests such as FSH is stability: AMH varies little across the menstrual cycle, so it can be drawn on any day, and it declines gradually and predictably with age rather than fluctuating month to month. It is essential to be clear about what AMH does and does not tell you. It estimates quantity, not quality, and egg quality is what falls with age and matters most for a healthy pregnancy. A low AMH does not mean you cannot conceive naturally, and a normal or high AMH is not a guarantee that you will. Its genuine strengths are predicting how the ovaries will respond to stimulation in IVF, which is why fertility clinics rely on it for planning, and supporting a diagnosis of polycystic ovary syndrome, where the excess of small follicles pushes AMH characteristically high.

Why take this test?

An AMH test is advised when planning a pregnancy, particularly after the mid-thirties, when investigating difficulty conceiving, and before IVF, where it guides the stimulation protocol and sets realistic expectations about egg numbers. It is used in the work-up for polycystic ovary syndrome, in which it is typically raised alongside irregular periods and the characteristic ultrasound appearance. It is also relevant before treatments that may damage the ovaries, such as chemotherapy, and when considering egg freezing, where it informs the likely yield. Some women simply want to understand their reproductive timeline, which is a reasonable use provided the result is interpreted by a doctor. Take care with what it can bear: AMH should inform planning, not be read as a verdict on your fertility, and a worrying number deserves a conversation with a gynaecologist rather than an internet search.
