I have been to the reproduction clinic today and was informed that my partner and I have no problems all our tests were normal. I was asked to consider which treatment we would want IUI or IVF, she said we have have 85% chance of natural conception but cant understand why it isnt happening, we have been trying for 18 months im 37 (38 in april) hubby is 33. Im seeking advice on best option to choose. im drawn to iui but concerned about the success rate as she said it was 5%, my biggest concern is my age as I do not want to be much older. suggestions/advice greatly received.
