Increased pregnancy after reduced male abstinence

Figures & data

Table 1. Data and basic descriptive statistics for volume (Vol: ml), concentration (Con: millions per ml), motility (Mot: percent of progressive motility), and sperm DNA fragmentation (SDF: % of sperm DNA fragmentation). The results represented 21 out of 40 patients that were able to provide ejaculates after 4 days of abstinence (ABS) followed by 4 days of recurrent ejaculation (REC).
