In Detail

AFC is one of the most reliable tests for assessing how many eggs remain in the ovaries. A normal count is 12-20 total (both ovaries). Counts below 6 suggest diminished ovarian reserve, while counts above 20 may indicate PCOS. AFC helps fertility specialists determine treatment protocols and predict IVF response.
