When a couple is planning a pregnancy, pre-conception counselling on diet and exercise is usually directed at the woman. However, this may change to include the prospective father. In-depth new research has suggested that men should be included in pre-pregnancy lifestyle discussions. The study revealed that if a man, in the pre-conception stage, has one or more of the following medical issues such as obesity, diabetes, high blood pressure, or high cholesterol, the quality of the sperm produced may be of poor quality. This raises the risk of a miscarriage or a pregnancy loss.
