Inability to conceive after 12 months of regular unprotected intercourse, resulting from impaired sperm or egg production.

Frequency: 70-80% of patients

Additional treatment options

Fertility counseling and support services

Psychological support services including counseling for the emotional challenges of fertility issues, stress management techniques, and guidance through treatment decisions.

psychological

Surgical intervention for anatomic causes

If anatomic abnormalities such as varicocele, uterine septa, or tubal obstruction contribute to abnormal gametogenesis, surgical correction may be indicated.

surgical

Lifestyle optimization and environmental assessment

Evaluation and modification of lifestyle factors including weight management, avoidance of reproductive toxins, stress reduction, and optimization of nutrition to support gamete quality.
