Question:
Is this why it is always a brother who prays at the retreats at this house?

Answer:
Yes, a brother does always pray even though we are having a home meeting and not an assembly meeting, because 1 Timothy 2:12 still holds true. “But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence. When someone prays publicly he prays for the whole group and we should add our “amens” if we are in agreement with his prayer (1 Corinthians 14:16).

If a woman prays out loud in a group with men present, she is usurping authority over man. The man is to pray or prophecy publicly because 1 Corinthians 11:4 shows the headship that God has established, and the place He has given to men and women. Christ represents God, who is His Head, the man represents Christ, who is his Head, and the woman represents the man, who is her head.
