Yes, since in both treatments the spermatozoa need to be of the best possible quality. In addition, it is not known exactly how many days are ideal in each case or for each patient, since they may vary slightly from one to another.
For example, in patients with few spermatozoa in the ejaculate (oligozoospermia), in order to increase the concentration of spermatozoa, it may be beneficial to have one or two more days of abstinence compared to normozoospermic patients (without any seminal alteration), who only need one day without sexual intercourse.
