At 40, with an AMH of 0.25, time is a key factor. While a normal follicular study is encouraging, a low AMH indicates a significantly reduced egg reserve. Given these factors, it is highly recommended to consult a fertility specialist promptly. \n\nYou should consider In Vitro Fertilization (IVF), which offers the best success rates for low ovarian reserve. Before starting, ensure a semen analysis and a tubal patency test (HSG) are done to rule out other issues. Continued use of supplements containing Coenzyme Q10 and micronized DHEA under medical supervision can support egg quality. IVF with donor eggs remains a highly successful alternative if needed.
