conclusions exposure to formaldehyde vapor can destroy testicular structure and decrease percentages of sperm count and progressive motility. the present study indicated that a reduction in the percentage of progressive motile sperm may be potentiated by noise (700-5700 hz) in the simultaneous exposure to formaldehyde and noise group. thus, it can be anticipated that simultaneous exposure to fo...
