Infertility is a common abnormalities nowadays, in about 50 % of cases the causes due to certain pathology in male.

One of the common criteria for determination of fertility status in males is seminal fluid analysis.

This study was conducted on 166 male attending infertility center in Al-Sadr teaching hospital, Najaf city during period from March to October 2009.

Our aim was to determine which seminal fluid analysis parameters are important to determine fertility potential and which male should be regarded as subfertile.

Seminal analysis was performed for every participant and compared with WHO criteria.

The result of the study showed that sperm count, motility and quality and seminal fluid volume is less in smokers than non smokers (P value for concentration and morphology < .0001) In addition to this the sperm count and motility was less in those who work in hot weather.

In conclusion the study showed that sperm count and morphology is more important than sperm motility and seminal fluid volume in determination of pregnancy.

The study also showed that smoking, obesity, and hot weather lead to decrease fertility.
