Chromosomal studies in infertile men with oligozoospermia & non-obstructive azoospermia.
BACKGROUND & OBJECTIVE Chromosomal anomalies have been postulated to be as one of the principal genetic factors in male infertility. Cytogenetic evaluation of men with severely compromised semen parameters reveals an increased incidence of chromosomal aberrations when compared with the normal population. The objective of this study was to determine the chromosomal constitution and sperm charact...
