Hello, thank you for your question!
First and foremost, you need to look at non-pharmacological measures for you and your spouse:
Encourage lots of color in your plates, lots of fruits and vegetables during your meals!
Be physically active on a regular basis, for 30 minutes a day or 150 minutes a week (active walking, training, etc.)
Make sure you get enough sleep and rest regularly
Have good stress management
Finally, some specialized clinics recommend a regular multivitamin for men, such as ProFertil Homme, but it is very expensive!
I hope I've helped you, but don't hesitate to ask any questions you may have!
