People with XX chromosomes and FSH insensitivity will usually be born with a vulva, vagina, and ovaries. Their ovaries may produce lower amounts of estrogen than is considered typical, and they may not produce fertile follicles (eggs). In adolescence, they may not develop secondary sex characteristics associated with a typical estrogen puberty and may not menstruate. People with XY chromosomes and FSH insensitivity may develop smaller-than-typical testes, may produce fewer sperm than usual, and may not be fertile.
