DH did a sperm test. All the results (volume, motology etc) were fine but dr flagged up low volume. She said this could be explained if he had split some of the sample when doing the test, however, since having a hernia operation 2 years ago, DH said he has noticed that he produces a lot less volume when ejaculating. I checked and it seems that this can be an issue, even if the volume/density etc are ok, as there is not enough fluid etc to get to the egg. Does anyone have any experience of this?
