There is a set of requirements for the quality of the semen, including overall quantity and concentration. There are many knobs one can tweak to increase the quality and abstinence of proper length (not too small and not too long is the most impactful and most straightforward) One day, and for most people, two days, is not enough to pass the threshold to consider donation successful. And for donation, it is actually not one threshold, but many. As you may see in the image with compensation per visit, there is a thing called vile. Ideally, one vial is one pregnancy. In practice, I was told that due to possible complications, it requires 9-12 vials to get a woman pregnant. => They do not allow donations more often than two days between visits, and if your physical and mental health is not ideal (level of stress affects the number of vials per visit as well), it may take 3-4 days.
