I am one of three siblings; my mother has three siblings, and my father has three siblings. We have two girls. Nearly all of my very very first cousins are female—in reality, it is a long-running laugh that ladies take over both edges of my loved ones and therefore you’ve got the patience of saints if you’re a male in my family (sorry, dad and bro!

The Mathematics Behind Determining a child’s Sex
Dr. Kimberly Langdon, an Ohio-based OBGYN and advisor that is medical Medzino, an electronic wellness business situated in California and Germany, tossed some (simplified! ) mathematics and technology our method to better understand gender assignment. (more…)
