Supporting a friend dealing with fertility issues can be challenging but incredibly important. Listen to them without judgment and allow them to express their feelings. Encourage them to seek professional help if they haven't already, and offer to accompany them to appointments if they wish. Be sensitive to their needs, as this can be an emotional journey. Sometimes, practical help, like cooking meals or simply spending time together, can make a big difference. Let them know you're there for them, no matter what.
