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.
Patient: Why do I have one
testicle and a
hole?
Doctor: You are being affected by an intersex condition called SDCI, or sexually dimorphic chimeric intersex in humans.
