Some people say: " you don't really know the value of something until you lose it". Do we really feel that way regarding certain parts of our body? Yes, we have heard of kidney, lungs or heart transplant, but what about the other parts of our body?

The truth is, our body is made of flesh, physical matter that once buried on the ground, is going to disintegrate, just like any other meat. But during our life on this beautiful earth, we want to preserve our body for as long and as well as we can. We have been granted with a pair of feet and of arms, and more toes and fingers than what we need. With that said, should we lose one or two, we are still left with enough to perform the intended job.  But what about the body parts that only come in one copy? Even more interesting. What are the body parts that cannot (yet) be replaced?

Penis

The penis is one of the most important organs for a man. And even to emphasize on how important that organ is, some men would rather save their phallus than their hearts (yes, it is that deep!). The penis is part of the male reproductive tract (which is completed by the testes, the prostate, the seminal vesicles, the ejaculatory ducts and the vas deferens). Most importantly, the penis can be considered as a man’s pride, and this due to the cultural connotations that have been associated with that organ. What are the things that can cause someone to lose their penis? For starters, we have severe traumas (that can cause serious blood flow obstruction to the penis, resulting in necrosis, gangrene and requiring penectomy (amputation of the penis). A male suffering from any subtype of penile cancer could also require penectomy if the cancer has already spread. Penis transplant has previously been attempted (in 2006) by a team of Chinese surgeons, but because of the emotional dismay that this had caused to the recipient’s wife, the organ had to be removed. Nevertheless, the surgery was considered successful, and maybe someday – in a near future – scientists would find an efficient way to make this organ more available for those who would lose it.

Brain transplant

Brain transplants have always been considered impossible, only theorically conceivable.

They are very different from head transplant: while a head transplant involves transferring one’s head to a new body, a brain transplant is thought to be the transplantation of an entire “being” to another body.

One of the setbacks to this scientific innovation is the fact that the nerve tissue does not heal completely, and because a “scarred” nerve tissue does not transmit impulses as efficiently as a healthy tissue, nervous integrity would not be maintained. However, in 1982, the chief of endocrinology at the Mount Sinai Medical Center (New York City), Dr. Dorothy T. Krieger, successfully completed a partial brain transplant in mice, and this was probably a stepping stone (no matter how small or big) in the world of medicine. Following that event, a team of surgeons from the University of Pittsburgh Medical Center (in 1982) attempted a partial brain transplant in a female patient who had suffered some neurological deficits secondary to a stroke, but the procedure was unsuccessful.
