There is no scientific evidence to support the claim that eating raisins with milk at night can benefit sperm. While both raisins and milk have some nutritional benefits, there is no research to suggest that consuming them together in this way has any specific effects on sperm.
Sperm health is affected by a variety of factors, including overall health and lifestyle choices such as diet, exercise, and smoking habits. To promote optimal sperm health, it is recommended to maintain a healthy diet that includes a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats, as well as engaging in regular physical activity and avoiding unhealthy habits such as smoking.
It is always best to consult with a healthcare professional for personalized advice on how to maintain and improve sperm health.
