In my brother-in-laws family we can trace back 100years and only male births occurred. My sister and her husband have 4 boys one of whom has 2 boys and another about to have a boy. MY b-i-l has a brother who has two sons one of whom has two sons and another one son. My B-I-L only has one brother.

Check Guiness Book of world records. They record everything. This sounds incredible...a little sad that there haven't been any women born into this family, but it's incredible none the less.

There is 50 percent chance that the new born will be male or female. It is like winning a lottery or drawing always black marble from the sack containing whole and black marble.
Mathematically it is possible to have unlimited sequences of birth of one gender only in the family but to have 5 same gender berth probability is 3,125% = 3 in 100
for 10 = 0.09765625% = one in 1,000
for 20 = 0.000095367% = one in 1,000,000
