As a couple I recommend to first get investigated. Male partner has only test to for, its complete sperm analysis. So you are recommended to go for it. For your spouse watch out if the menses are regular. Any irregularlity has to be corrected initially. Get a whole body blood check up for both so as to know the deficiencies and any concern issue.
Next Steps
I would suggest to consult Homoeopath and then go for medicines.
