My sincere advise for you is that please dont look outside as you have been advised by other friends.
my wife had the same issue in our marriage years after our wedding. Her falopian tube is blocked and also had fibroid hence sperm is not entering her but we had to continue seeing a doctor and a gynacologist in a teaching and private hospital and looking unto God in prayer throughout for the divine intervention today the rest is history. Today we had 3 incredible boys now to the glory of God. God has put a smile in us by also turning the fibroid to fine boys and giving us a testimony.

please dont look outside stand with your wife sir
