Orwig teachs the monkey Grady - OHSU that the group breeds
Not long ago, authoritative magazine Science is online published a such research: Organization of spermary of rhesus of green early days is put to rise by aspic, when after this monkey adolescence, the back skin that transplants spermary organization to it again or scrotum are hypodermic, spermary organizes unripe long maturity and arose to have the spermatozoon of be fertilized function. Adopt external fertilization technique next, bear the monkey that gave health [1] . This research teachs a group to present as leading role to finish by Orwig of Pittsburgh university college of medicine. This research proves, "Technology of " of spermary organization transplanting anticipates OK at human reproduction medicine applying clinical.
What is spermary organization transplanting?
Spermary organization transplanting is fertility of a male saves a technology. Be in before clinical on, it is the spermatozoon that gets maturity from inside the spermary of grown man freezes next put, when doing external fertilization again defrost spermatozoon. " spermary organizes transplanting " technology to make clear now, before the male of the preadolescence is making the treatment that puts cure to change the scathing fertility such as cure, can freeze the spermary organization that puts oneself, the constituent defrost that after waiting for manhood, puts aspic anabiosises, transplant next the skin of oneself falls or in scrotum, with period generation practicable spermatozoon.
Why should undertake spermary organizes transplanting?
Current, the surviving rate of the boy that has cancer although prep above 80 ％ , but because the survival of male children cancer of 30 ％ treats the to spermary loss in the process in cancer too serious, produce barren situation possibly after manhood [2] . Because these boys are being done,this is when putting cure to change cure, the essence in spermary does a cell to may be used up formerly, and essence of life does a cell to become spermatozoon in become divided of the meeting when manhood formerly. The birth problem that how solves these patients becomes the difficult problem that puzzles scientists all the time.
Some readers can ask the likelihood, why not spermatozoon refrigerant? Because boy of green early days has not produce sperm, cannot adopt this kind of measure so. And to grown man, basically can freeze before putting cure to change cure put spermatozoon, do not need aspic to put spermary organization.
Spermary organizes coloring scheme, rich essence of life is contained to do a cell formerly in normal organization - – Scimex
Spermary organizes the development foreground of transplanting
Actually spermary organization transplants and heterogeneous transplanting had had old research in experimental animal. Come from small rat, goat, hare, dog, cat, horse, pig, ox, monkey crudely spermary organization, transplanting can mature below the back skin to immune blemish naked rat and generation has the spermatozoon of be fertilized ability, produced healthy filial generation through external fertilization technology finally.
Clinical research established these experimental eventuate solid base. After spermary organizes human body to transplant from body, among them spermatozoon produces development mechanism to remain to study further and be optimized. Spermary organizes transplanting and heterogeneous transplanting, still need to enhance technical security and effectiveness at present, to clinical talent is enough large-scale at applying clinical.
To this research, germany bright this especially big learned scholastic Schlatt comments on: Had this paper, the ethical committee of research organization of medicine of world each country will allow generally begin (spermary organization transplants) clinical research. Professor Orwig group and his co-worker already collected the spermary of more than 200 boy to organize at present, clinical research will be begun in order.
