• Poor sperm motility: Sperms unable to move effectively
• Abnormal sperm morphology: Defective shape or structure
• Hormonal imbalance: Deficiency of testosterone or gonadotropins
• Obstruction in reproductive tract: Blockage in vas deferens
• Infections: Sexually transmitted diseases affecting sperm production
• Lifestyle factors: Smoking, alcohol, stress, and exposure to toxins

Step 2: Causes of infertility in females.

• Ovulation disorders: Irregular or absent ovulation
• Blocked fallopian tubes: Prevent fertilization
• Hormonal imbalance: Affecting menstrual cycle
• Endometriosis: Growth of endometrial tissue outside uterus
• Uterine abnormalities: Fibroids or structural defects
• Age factor: Decline in fertility with age
• Infections and diseases: Affect reproductive organs

Step 3: Conclusion.
