The current male infertility crisis is attributed to the increasing rate of infertility; many congenital and acquired conditions have been recognized, but currently, 70 % of the causes are still unknown despite advances in andrology. Many cases are diagnosed as having unexplained infertility, while a large number are recognized as being idiopathic. A prospective cross-sectional study was held in Mosul city, Iraq, at an outpatient infertility clinic. The study includes 216 males of subfertile couples. History examination and investigation were done, seminal fluid analysis and testosterone, follicle-stimulating hormone, prolactin, and zinc were assessed statistical analysis by IBM SPSS Statistics software. percentage of risk factors and encountered seminal abnormalities with significant difference in abnormal<15million/ml sperm count of those 20-30 years old (57%, p-value 0.001), and those have free work constitute to 69% patients with abnormal progressive motility<30% (p-value 0.036), primary infertility had higher percentage of volume ≤1.4 and count <15million /ml at than secondary infertility(p-value 0.003,0.001)and those with previous miscarriage have higher percentage of abnormal viscosity(p-value >0.14). BMI significantly affects testosterone level inversely (p-value 0.010). Smoking significantly has a volume ≤1.4ml, and previous corona infection significantly affects low sperm count (<15 million) (p-value 0.16, 0.21, respectively). Oligoasthenospermia is common in subfertile couples, and lifestyle factors, obesity, and coronavirus infection are among the most common factors related to male infertility.
