Hi , How do you do ? Let me give you the positive part, you are still 31 yrs, till 35 yrs every lady has good chance of pregnancy. If your periods are irregular , it means you are not ovulating every month on time. This could be due to Overweight - Your weight has to be Weight(in Kgs)= Height (in cms)-100 eg- If height 160cms, 160-100= 60-65 kg is expected weight. Once you reduce weight to normal range, you won t need any medicine to get periods or to get pregnant & pregnancy will be healthy. To reduce weight - NO FASTING, No junk food/ fast foods/ red meat, reduce snacks in between meals Have low calories food, high proteins Regular exercise, aerobics , yoga, brisk walking try to reduce 2-4 kgs / month. Don t hurry on weight reduction, it will be difficult to maintain. As soon as you reduce atleast 5 kgs , you will see changes. Even if you are in normal weight range , try this schedule, it will help. Other possibility is Abnormal Thyroid profile or Serum Prolactin level. This can be corrected by medications. Any treatment for pregnancy needs correction of these problems as a pre-requisite Tube is the bridge between uterus & ovaries , where the egg meets the sperms & baby is formed, from here the embryo moves to the uterus. If this is blocked 1. Open or by Laparoscopically clear the block 2. As you want to avoid the surgery, only option is IVF / ICSI. Here you will be given hormone injections to stimulate more eggs. Once they are ready they are pulled out of body under scan guidance. The same day husband s semen is collected & each egg is injected with one sperm. This forms in the embryo or baby in the lab. Once the embryo is of right size, 1 or 2 embryo are kept back into the uterus . Remaining embryos are kept frozen in your name. It is not by surgery, just like a scan. After delivery of baby, you can have next baby with those frozen embryo. You can keep having baby till the embryos get over. Age of embryos will be your present age. Embryo s age will not increase with your age. So you can have pregnancy irrespective of your age Hope I have clarified your queries , do write back if any more queries All the best Dr.Balakrishnan
