Being in a relationship is a joint effort so trying for a baby should be no different.

According to the Irish Examiner, the chair of nursing and midwifery at Trinity College Dublin, Professor Cecily Begley, believes that men need to give alcohol the boot completely for a year when trying to conceive. As well as saying goodbye to booze for 12 months, Begley also believes that men need to control their weight and increase their intake of fruit when they reach that stage of their relationship. Being underweight or overweight can have a negative impact on a man's sperm, and it can prove problematic for a couple's sex life because weight problems can affect a man's libido and performance. Sticking to a balanced diet that includes fruits, vegetables, lean proteins, grains, and dairy, and fitting in regular physical activity can help maintain a healthy weight. While Begley believes that men should give up the beer completely while trying for a baby, research shows that it is okay for men to drink a limited amount during this period. Sperm is affected by tobacco, alcohol, and drugs and the combination of these three may lower sperm counts and slow motility so it is wise to reduce your alcohol intake when trying to conceive.
