If I have an infection or a sexually transmitted disease will it impact my YO Home Sperm Test results?

In the presence of sexually transmitted diseases causing bacteria and viruses such as Neisseria gonorrhea, cytomegalovirus (CMV), human papillomavirus (HPV), herpes simplex virus, and Chlamydia trachomatis your potential sperm motility may be affected. YO may report results in LOW MSC RANGE in the presence of sexually transmitted diseases or infections but in the absence of such disease or infections, your sperm could be in the MODERATE/NORMAL MSC RANGE. This is one of the reasons YO recommends you seek medical advice if both of your YO tests are LOW.
