title: Importance of semen preparation in avoidance of reduced in vitro fertilization results attributable to bacteria.
abstract: Although the physical treatment of semen for IVF and related procedures is sufficient to remove most organisms present in semen, the pathogenic varieties tend to be more resistant. The supplementation of oocyte culture medium with both penicillin and streptomycin was associated with the eradication of 100% of organisms in the current study. In these circumstances, the presence of pathogenic organisms in the untreated semen is not associated with reduced oocyte fertilization in vitro.
