SUMMARY: A scientific determination of fertilization ability of the sperm can be made by motility, viability and morphological examinations that are called as potential fertility criteria. Some previous studies documented only the total morphological defect rates without including the morphologic subjects. As it is recorded in many studies, the success of IUI, ICSI and IVF depends mainly on the quality of the collected semen. 1) Determine and classify the common morphological defects and rates of sperms. 2) Analyze the effect of age on the sperm abnormalities and to assess the impact of environment on changing normal sperm characteristics. 3) Determine the common types of semen abnormalities (Asthenoterato-zoospermia, Asthenozoospermia, Azoopyospermia, Azoospermia, Hypospermia, Oligoasthenoteratozoospermia, Oligoasthenozoopyospermia, Oligoasthenozoospermia and Teratozoospermia). 4) Determine the range of teratozoospermic index (TZI) and sperm deformity index (SDI). A prospective case series study for 566 men of infertile couples who were requesting semen analysis was applied to those came to the ULTRALAB laboratory center main campus and ULTRALAB branch of the Sudan Assisted Reproduction Center (SARC), Khartoum, Sudan. Data collection was done for 20 months from April 1st, 2010 to December 31st, 2011. analysis of semen samples was done using Computer Assisted Semen Analysis (CASA). 1) The study demonstrates that there are differences in normality and abnormality of sperm morphology parameters of sperm between Sudanese population and other studies including WHO standards. 2) SDI and TZI were higher in overall semen as well as in abnormal semen samples. 3) Common semen abnormalities were oligoasthenoteratozoospermia, asthenoteratozoospermia and asthenozoospermia. There are differences in sperm morphology of both normal and abnormal parameters between Sudanese population and other studies including WHO standards.

RESUMEN: Se realizó una determinación científica de la capacidad de fertilización de los espermatozoides mediante motilidad, viabilidad y exámenes morfológicos denominados criterios de fertilidad potencial. Algunos estudios previos documentan solamente el total de las tasas de defectos morfológicos sin incluir a los sujetos morfológicos. Como se registra en muchos estudios, el éxito de IUI, ICSI y FIV depende principalmente de la calidad del semen recolectado. Los objetivos de este trabajo fueron: 1) Determinar y clasificar los defectos morfológicos comunes y las tasas de espermatozoides; 2) Analizar el efecto de la edad en las anomalías de los espermatozoides y evaluar el impacto del medio ambiente en el cambio de las características normales de los espermatozoides; 3) Determinar los tipos comunes de anomalías en el semen (astenoterato-zoospermia, astenozoospermia, azoopiepermia, azoospermia, hipospermia, oligoastenoteratozoospermia, oligoastenozoopermia, oligoastenozoospermia y teratozoospermia); 4) Determinar el rango del índice teratozoospérmico (TZI) y el índice de deformidad del esperma (IDE). Se realizó un estudio prospectivo de series de casos en 566 hombres, de parejas infértiles, que solicitaban análisis de semen en laboratorios ULTRALAB y la sucursal de ULTRALAB del Centro de Reproducción Asistida de Sudán (SARC), Jartum, Sudán. La recolección de datos se realizó durante 20 meses, desde el 1 de abril de 2010 hasta el 31 de diciembre de 2011. El análisis de las muestras de semen se realizó mediante el análisis de semen asistido por computadora (CASA). Existen diferencias en la normalidad y anormalidad de los parámetros de la morfología de los espermatozoides entre la población sudanesa y otros estudios, incluidas las normas de la Organización Mundial de la Salud. Los parámetros SDI y TZI fueron más altos en el semen general, así como en muestras de semen anormales. Las anomalías comunes del semen fueron oligoastenatoatoospermia, astenoteratozoospermia y astenozoospermia. Existen diferencias en la morfología de los espermatozoides de los parámetros normales y anormales entre la población sudanesa y otros estudios que incluyen las normas de la Organización Mundial de la Salud.
