title: Effect of peritoneal fluid on sperm motility parameters in women with endometriosis.
abstract: To clarify the effect of peritoneal fluids (PF) of women with various stages of endometriosis on sperm motility, we utilized computer-aides sperm analysis (CASA) to analyze sperm movement characteristics. PF was collected in the early follicular phase (days 4-8) of the menstrual cycle from 48 women undergoing diagnostic laparoscopy. Only sperm samples having normal sperm parameters were chosen for study. Swim-up separation was performed for 1 h at 37 degrees C. Sperm suspension was mixed at a ratio of 1:1 with each of the following four groups: group 1, human tubal fluid (HTF) with 10% fetal bovine serum (control), group 2, normal PF (n = 16); group 3, minimal or mild endometriosis PF (n = 16); and group 4, moderate or severe endometriosis PF (n = 16). The mixtures were analyzed at 0, 1, 3, 6, and 24 h of co-incubation using the CASA system. At the end of the 24 h incubation, Supravital staining of sperm was done to check the viability of sperm in each group. Only time (F = 126.6, p < .001) has a significant effect on sperm motion parameters. At 6 h, sperm velocity (mean curvilinear velocity and mean straight line velocity) of the PF groups was significantly greater than that of the control, but there was no significant difference between each PF group. At 24 h, the PF groups maintained 50% of initial sperm viability, compared with 13% of initial viability in the control group (p < .001). There was no adverse effect of PF in patients with endometriosis on sperm motion parameters.
