No worries, we welcome hubby to come to this forum too. Regarding your question, as i ever asked this same question to a gynae in KK.
His reply is try baby for 1 year, if there is no outcome, then go and seek help. We tried for about 6mths, then we got this baby!
beside that, eating balanced diet, rest well, exercise, both physical and mental health is important
Hope this will help
