Sexually dimorphic chimeric intersex are what happens when a pregnant mother (either intersex or female) produces or is in contact with quantities of
testosterone in the third trimester causing a male and female twin to fuse into one, then split when
testosterone lowers, then the smaller twin is reabsorbed by the larger one. This leaves the resulting child with a penis, one
fallopian tube, a uterus, one accessory gland, half the average amount of eggs, and one small testicle attached to the volva tucked inside an otherwise normal vagina.
