Brazilian couple Irineu Cruz and his wife Jucicleide Silva have been trying for the past 20 years to conceive a daughter without success.

They have 13 sons ranging from 1 month to 18 years old. When the couple got together, they planned that the mother would name the girls while the father named the boys. The father has named 13 of their children who are all boys while the mum is yet to name any child because they don't have a daughter yet. And the woman says she will continue to bear children until she gets a daughter. See more pics and the video after the cut...
