Một người nam trưởng thành, sinh hoạt tình dục bình thường và sống chung với vợ lâu hơn 1 năm mà không có con, cần được thực hiện một số điều cơ bản sau:

- Siêu âm tinh hoàn.

- Xét nghiệm máu tổng quát và đo lượng hormone testosterone, LH, FSH.

- Thử nghiệm tinh trùng, tinh dịch.

- Tinh trùng được quan sát dưới kính hiển vi trong khoảng 1 giờ sau khi xuất. Bình thường, khối lượng tinh dịch là 2-6 ml, số lượng tinh trùng trong mỗi ml phải có khoảng 20 triệu con hoặc nhiều hơn. Trong đó, có ít nhất 50% tinh trùng linh hoạt, bơi nhanh và có ít nhất 70% tinh trùng có hình dạng bình thường.
