<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had one child after many attempts through IVF as I have no fellopian tubes due to 2 ectopic pregnancies I have been trying for the last 3 years to have a second child but no success. At harvest I have 7 to 8 embryos all very strong but when they are transfered I have problems don t fall pregant. I am 40 years old, is there anything I need to be doing to strengthen my placenta , I lose them every time I have had about 15 transfers, can you advise me.  <response>: Hi, Lena, you are lucky to have one child. You have had fertility treatments in the past know very well that it takes time patience nothing in the world can guarantee a pregnancy. In addition with passing years, even in women with patent tubes fertility declines. So, be patient compliant with your treatment. Dont take too much stress as it will also decrease your fertility potential dont forget to spend quality time with your kid to make yourself relax and optimistic. Wish you best of luck.
