Brucella is generally contracted from animals or animal products (milk etc) rather than other people. It can be treated with antibiotics and a man of marriable age (young fit and otherwise healthy) is likely to recover quickly from infection especially if treated with antibiotics. If a new wife does catch the organism and gets pregnant quickly after the marrage there are chances of complications as the brucella can pass from the mother to the unborn child these range from loosing the baby, baby coming too early to endometriosis in mum after the birth. I would get married but I would then wait until the husband is brucella free and then a further 8 weeks have passed before starting a family. Brucella is especialy risky for baby in early pregnancy. Wait to start a family, using contraception for 3-6 months is far better than loosing a baby and it might be fun "practicing".
