need to take a higher dose of Letrozole?

Hi,
Welcome to ehealthforum,
Few women need 2-3 cycles of the infertility treatment to help with pregnancy. If the first 3 cycles are not successful, then it will be combined with HCG injections to increase chances of pregnancy. If these also fail, then options of IVF or ICSI should be considered. Many times the treatments fail if there are problems with sperms like altered morphology, or defective acrosomal protein which play a major role in fertilization of the egg (in these circumstances, ICSI helps). Discuss about the further course of treatment and these options in detail with your treating gynecologist/infertility specialist and proceed with further management as instructed. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet rich in zinc content to ensure better maturation of eggs and sperms. Monitor cervical mucus changes and the BBT (basal body temperature) charting to predict your ovulation (serial follicular scans will also help) and time your intercourse for having fruitful results. Have intercourse in positions that allow for deeper penetration for high deposit of semen. All the best.
Take care.
