Short Abstinence Is A Good Strategy For Treating Very Severe Oligoasthenoteratospermic (Oat) Couples.

Sexual abstinence is considered one of the several factors that influence sperm quality. Recent studies show that a shortening could be beneficial mostly in OAT patients. The present study has the objective to study the efficiency of a second semen sample produced after a short abstinence in severe OAT infertile patients. retrospective study. 127 cycles performed at our University Hospital Infertility Center (May 2014 - May 2018) were divided into two groups: Group 1 (Study Group): 75 cycles. Very severe OAT patients with the following characteristics on the day of treatment: 1) count < 0.2x106/ml, without progressive motility; 2) count > 0.2x106/ml, and no total or progressive motility; 3) 0% normal morphology. Two samples were requested. Group 0 (Control Group): 52 cycles. Normospermic or light OAT patients programmed for treatment the same day of at least one couple of Group 1. Semen parameters and outcomes were compared between Groups. Group 1: 75 cycles (59 fresh, 16 with thawed oocytes), Group 0: 52 cycles (43 fresh, 9 with thawed oocytes). Ovulation was induced with r-hCG administered 36h before oocytes retrieval. Oocytes cryopreservation were carried out by vitrification/warming. ICSI was utilized as insemination technique for all oocytes. women’s mean age Group 1 (36.96±3.95) and Group 0 (37.4±3.92) and men’s mean age Group 1 (40.57±5.49) and Group 0 (40.56±5.41) were not significantly different (P= .834, P= .954 respectively). Conventional semen parameters were compared between sample of Group 0 vs 1° sample of Group 1. All parameters, excluding volume, resulted significantly different (P
