Description Mammals including human beings are exposed to thousands of chemicals including
pesticides used in agricultural practices, industrial processes and other domestic practices.
High level of pesticides residues existing in the environment have been reported to cause
adverse effects on reproductive health of animals possible by interfering with the hormonal
functions. The present study was designed to examine the possible effects of environmental
contaminants on the male and female fertility parameter in Rattus rattus, Tatera indica and
Bandicota bengalensis inhabiting South West region of Punjab as compared to rats
inhabiting Punjab Agricultural University (PAU) Ludhiana which were taken as control. The
weight of vital organs was significantly lower in Bathinda rats as compared to Ludhiana rats.
In biochemical studies the content of proteins, phospholipids was less while acid
phosphatises (ACP) were significantly more. The total lipids and cholesterol were
significantly high while alanine amino transferase and aspartate amino transferase (ALT,
AST) were significantly higher in Bathinda district rats as compared to Ludhiana rats. Lower
sperm motility and sperm concentration alongwith significantly higher sperm abnormalities
were observed in Bathinda rats as compared to Ludhiana rats. In male testosterone levels
were low, while estradiol and progesterone levels were also low in female rats of Bathinda
district. Pesticide residue of chlorpyrifos was detected in plasma and malathion was detected
in liver samples of Bathinda rats. Histopathological evaluations of testis of the Bathinda rats
revealed some distorted semniferous tubules and degenerative changes in semniferous
tubules with reduced spermatozoa. In female rats there was higher number of atretic follicles
in all stages of follicles and the average diameter of all the growing follicles were also less in
the ovaries of Bathinda rats at P
