What This Test Measures
Your doctor will administer a hormone (follicle-stimulating hormone, or FSH) through a series of injections over a few days. Blood samples will be taken before and after these injections to track hormone levels and ovarian activity. This helps determine if your ovaries are responsive to stimulation, which is important for fertility treatments.
Why It’s Done
This test is often used in women who are trying to conceive but have irregular periods, low ovarian reserve, or unexplained infertility. It may also be part of a broader evaluation for conditions like polycystic ovary syndrome (PCOS).
How the Results Are Used
Results help doctors understand how well your ovaries produce eggs in response to stimulation. This information guides decisions about fertility treatments, such as in vitro fertilization (IVF) or other hormone therapies.
What to Expect Before the Test
You may need to avoid certain medications (like birth control) or have a baseline blood test before starting the stimulation phase. Follow your doctor’s instructions carefully to ensure accurate results.
