Hi wondering if anyone can shed any light I had my 4th nhs iui today and today as well as the first 3 iui's my hubbys sperm has been clumped together first month was 40% then 2 @70% and today 63%. I have asked why and they dont seem to b able to answer us fully. They don't seem to be concerned. I have been reading up on this and I fear this could be due to antibodies? Does anyone know if there is a separate test not done on at this stage to confirm antibodies We r on waiting list for ivf. Will we get answers at that stage? I cant help feeling this is why we r not achieving pregnancy. Could a pregnancy still happen? I no they wash the sperm and separate them but I've read if there's antibodies it mite not be able to get through the egg anyway? Thanks in advance!
