Background: Male factors contribute to almost 50% of infertile
couples . Deleterious effects of
tobacco smoking on
male reproductive system are well known.
Research studies
report contradictory findings about the effect of
tobacco chewing on
male fertility . Aim and
objectives: To study effect of
tobacco chewing on seminal
parameters in
male partners of infertile
couples . Material and
Methods: Present study was conducted on 100
male partners of infertile
couples (50 tobacco chewers and 50 non-chewers) in
age group of 21-40 years in the
semen analysis laboratory in department of
Physiology of
Government Medical College, Nagpur from October 2014 to March 2016. Seminal
parameters like volume of ejaculate,
sperm count ,
sperm motility and motile
sperm count were measured and compared in both groups.
Result: Tobacco chewers had significantly lower values of all the seminal
parameters as compared to non-chewers. Significantly low values of all
parameters were observed in severe tobacco chewers as compared to mild and moderate tobacco chewers.
Conclusion: Tobacco chewing has adverse effect on seminal
parameters of
male partners of infertile
couples thus proving its pronounced
role in
male infertility . Severity of this effect increases as duration of
tobacco chewing is prolonged.
