The most important thing is to abstain 2-7 days before you plan to produce the sample and send it back. For many clients, this is the most difficult part! We recommend 3-4 days for the optimal quality of sperm.
In light of this, you can plan ahead and choose the day you intend to product and return your sample. This should be on a Monday, Tuesday, Wednesday or Thursday, so that it arrives at our clinic during the work week.
You should not use the kit on a Friday, Saturday, or Sunday.
