Can chlamydia infection cause permanent problems in male fertility?

Hello doctor,

I am a 35 year old male. Earlier this year, I had chlamydia infection for about four months. I have been clear of the infection since about seven months. Now, my partner and I are trying to conceive. I had a semen analysis and the results were not great. The worst part is the morphology. Only 2 % of my sperms are formed normally. The rest are abnormal. So my two questions are: is it possible that the chlamydia is the cause of this? Can chlamydia cause permanent problems for male fertility? Is there anything I can do to increase this percentage? I am taking vitamins and exercising. I am soon going to cut out sugars and watch my diet. Will this help? Are there other things we can do? Lastly, the evaluation said I have a 'poor prognosis' in terms of my morphology. And overall it said I have 'moderate male factor' circled on my sheet (I assume that means - moderate male factor infertility?). But the person who did the analysis said I am suitable for IUI's. How successful are these in my circumstance? I will attach a photo of the evaluation so you can see all my numbers. I have only blocked out personal information. Sorry for all the background. Again three questions: Did chlamydia play a role in my current situation? Anything I can do to improve my normal morphology? How successful is IUI in my circumstance after looking at my evaluation?

Thank you doctor,

As I said, I have been clear of chlamydia for several months. What I am asking is: once I am clear, can my current sperm situation be attributed to a past infection of chlamydia? Is there anything I can do to improve my sperm morphology?
