He can test whenever he’s ready! However, it’s best not to have intercourse or ejaculate 2-5 days before testing so we recommend targeting testing accordingly.
Note: Not for post vasectomy testing.
The Proov Male Fertility Test measures Motile Sperm Concentration (how many sperm are actually moving) and sperm quality. The YO app then compares your partner’s results to laboratory standards and to other men who have fathered children.
MSC is the number of moving sperm in 1 milliliter of your partner’s sample. The Proov Male Fertility test is an important test because it checks for moving sperm — a critical characteristic since sperm needs to be able to swim to the egg!
Since sperm must be able to swim to the egg for conception to occur, knowing your partner’s concentration of moving sperm is an important piece of the fertility puzzle. The Proov Male Fertility Test also provides a MSC ranking and a personal reference video, which can be shared with your doctor if needed.
