Hi there ~
I understand your concerns. However I would like you to focus on the positive. If you had 52% abnormal morphology you probably have 48% normal morphology of sperms. I believe that with the number of sperms in your sperm count
that have 75% motility you have enough sperm to fertilize a healthy ovum. I do not think that there is any cause for concern and you might have to do your best and leave the rest to nature. If you are having troubles conceiving a child with your wife, you might need to have IVF or IUI done to increase the chances and please consult a specialist for the same.
I hope this helps. Take care and have a lovely day!
