TO STUDY THE IMPACT OF SMOKING ON MALE FERTILITY OF BHAGALPUR DISTRICT OF BIHAR

ABSTRACT

The purpose of this study was to determine the impact of tobacco use on male fertility in the Bhagalpur district of Bihar. A total of 20 men from infertile couples were enrolled in this cross-sectional study, and their sperm samples were collected along with their general information. General characteristics such as sperm concentration, count, motility, and morphology were observed. The sperm chromatin dispersion (SCD) assay was used to calculate the sperm DNA fragmentation index (DFI). A DFI 30% threshold was used to classify groups as normal (DFI< 30%) or abnormal (DFI > 30%). The smoking habit was found to be significantly related to sperm motility, morphology, and DFI. However, there was no correlation with sperm count. In this study, 5 out of 20 sperm samples had abnormal motility (< 32% progressive motility) and 9 out of 20 had abnormal sperm morphology (Teratozoospermia). Our findings revealed no link between DFI and motility or morphology. The sperm DNA fragmentation index did not have a strong correlation with other sperm parameters. As a result, as an additional step in determining sperm fertility, a sperm DNA fragmentation assay should be performed.
