Objective: To assess the contribution of chromosome on sperm production. Methods: During a 2 year period from October 1999 to December 2001 a total of 200 male patients were included in the present study. The study was carried out at Kufa Medical College, Kufa, Iraq. Blood culture, chromosomal harvesting, Giemsa stain, C-band technique and C-band size calculation have been conducted according to the standard methods. Results: No statistical differences have been recorded in the C-band size distribution level among the infertile groups compared to normal control. The functional relationship between C-band, euchromatin and the total length of the Y chromosome showed a strong correlation coefficient among the infertile groups (oligospermia, azoospermia) as well as the normal control. Conclusion: In our qualitative study the C-band size of the Y chromosome has no effect on spermatogenesis. The decrease in the size of Y chromosome is due to the decrease in both the heterochromatin and euchromatin regions.
