Evaluation of Sperm Impairing Factor from Serratia marcescens as Male Contraceptive in Mouse Model

Figure 3

Representative photomicrographs of histological examination (day 90) of reproductive organs, viz., testis, cauda epididymis, and vas deferens of left side (a, b, and c, respectively) and right side (d, e, and f, respectively) receiving 400 µg SAF. Left testis: (a) normal seminiferous tubules (indicated by arrow head); left cauda epididymis: (b) tubules filled with spermatozoa (indicated by arrow head); left vas deferens: (c) normal tissue histology (abbreviated as N). Right testis: (d) degenerative changes in the seminiferous tubules and empty testicular lumen (abbreviated as ETL); right cauda epididymis: (e) empty epididymal lumen (abbreviated as EEL); right vas deferens: (f) normal tissue histology (abbreviated as N).
