Although two sex organs are present during the embryonic stages of all birds, once a chicken’s female hormones come into effect, it typically develops only the left ovary. Several medical conditions can result in an apparent sex change in humans, where the appearance at birth is somewhat, mostly, or completely of one sex, but changes over the course of a lifetime to being somewhat, mostly or completely of the other sex. As a result, the person has some or all of the physical characteristics of a female, despite having the genetic makeup of a male. Humans are most commonly said to have “a sex change” when they undergo sex reassignment therapy, that is, a set of medical procedures undergone by transsexual people to alter their sexual characteristics from male to female or from female to male.
