One other funny story. We had a guy in another office have four boys. He and his wife decided to try one more try for a girl. They had twin boys.
Wife and I had tried for 12 years with no luck. I had pretty much given up. About that time (I was 41) I got on a herbal kick and was taking half a dozen+ including Ginseng.
Well, voila wife unexpectedly gets pregnant and with twins no less.
