Why Our Clients Love YO
S S Vasan | MBBS, DNB
“YO addresses the unique problems of accuracy and privacy. It is a home kit that provides a precise assessment of Moving Sperm Concentration (MSC). Testing moving sperm is critical in a home test because, with a clear video to back it up, the results allow the man to approach the doctor with evidence of a problem. I see YO as a game changer in India and globally because of the profound need for a test of this type as a first step in the process of diagnosing and treating male factor infertility in a timely basis and also taking preventive steps.”
Abraham Lightman | MBBS, DNB
“From my perspective, a digital sperm test like YO that accurately reports Motile Sperm Concentration is an excellent screening tool for the consumer. When a couple arrives at my clinic with a YO result in hand and they can also show me a video that verifies the results, I can quickly assess if there is a male factor issue that requires investigation. I believe this motivates the couple to seek help earlier in the process and that’s very beneficial to both the doctor and the patient.”
Kenan Omurtag | MD
“YO is the first FDA approved smartphone based home sperm test that allows men and their partners to reliably screen sperm count and motility (moving sperm concentration) in the privacy of their own home.”
Stanton Honig | MD
“YO Sperm home testing has taken direct to consumer diagnostic testing to the next level. In the past, at home sperm testing could only evaluate sperm counts. YO Sperm evaluates motile sperm concentration which is a much more important way to test for a male problem. All patients with abnormal results should be evaluated by an M.D. specializing in reproductive medicine. Patients within a reasonable range should still be checked after one year with a formal sperm test as other parameters may be important.”
Katherine Betcher | MD
“An easy to understand, more private method of testing. Many of my patients’ husbands were more interested and willing to undergo testing with this method. I am comforted by the fact that it is backed up by the FDA and the ASRM, with an article in Fertility and Sterility.”
Natan Bar-Chama | MD
“A male contribution to infertility is common and should be assessed early on in a couple’s path to achieve parenthood. To enable a man to assess his motile sperm concentration in the privacy of his home, using the FDA approved YO home sperm test presents a significant opportunity for a couple to become more educated about their fertility potential.”
Dan Nayot | B.Sc., M.Sc., MD, FRCSC
“Providing men with easy to use, at home testing options is the future of how we address fertility challenges upstream from the fertility clinic. The YO Sperm Test enables earlier detection of potential sperm issues, allowing patient to pursue timely interventions and improve outcomes.”
