Help in understanding

Could someone help me understand this better?

My left ovary is blocked. I went in for IUI round 2 and because my mature follicle was on my left side my dr cancelled the iui and instead suggested we do medical timed intercourse.

From my online research what I understand is that the ovary releases the egg to the tube. But if the ovary is already blocked where is the egg gonna go ? It’s not making its way to the fallopian tube anyway I don’t think.

Could someone help me understand this because I can’t find answers on Google much.. im trying to understand if this would even work if the egg can’t release on left tube side and why would my dr even suggest timed intercourse this cycle if that’s the case?
