Natural breed announces failure repeatedly, turn and the choice is test-tube. Come from May 2015 in April 2019, undertook artificial be fertilized 5 times early or late, but all end in order to fail.

"This need has a complete meet an urgent need beforehand case, compare mammal, the physiology rhythm of spot turtle is more slow, the omen that this means occurrence accident also won't resemble mammal so apparent, once appear accident circumstance, can bring not reversible harm " .
Rich of famous popular science advocate beautiful corrode, from Chinese geological university (Wuhan) life science is zoologic after direction graduates, be engaged in wild animal protecting relevant job, from rise 56 years ago, begin to pay close attention to spot turtle this one species. When beautiful corrode accepts media to interview, say: "Current, inside alive bound limits, large terrapin kind species is test-tube the technology is not quite mature, accordingly, what be aimed at female spot turtle this is test-tube also be to risking huge risk doing. " look in beautiful corrode, the international terrapin that assumes this job lives allied (protection of wild living things learns TSA) , international (WCS) square, as square as zoo of Chinese zoo association, Suzhou advanced 4 test-tube undertake to female spot turtle again below the circumstance that fails test-tube, be particularly bold have the action that take on again, but the likelihood has a few problems on the technology.

What to spot turtle we understand is too little
A consensus with relatively unified industry is, we are right spot turtle this a group of things with common features group of understanding too little. Even, the female spot turtle that dies only then comes from He De after all, also do not have final conclusion temporarily.
"We learn to the zoology of spot turtle, behavior, the respect research such as heredity is not comprehensive, fundamental job was not accomplished, tell the truth, differ from the knowledge that saves need of place of a species too far. " Wen Chengshui, "According to a few stories that see now, oosperm once had, just proportion is very small, yo of foetal hair of the embryo in hatch process died to a week left and right sides. " hear assist to have a bold hypothesis, if female comes from red river drainage area, the level of genetic become divided of it and turtle of that spot of the Yangtse River may achieve subspecies above, oosperm proportion is small because reproduction is kept apart,the likelihood is. And if be turtle of red river spot, the temperature that place of that oosperm hatch needs is in likely 35 to 36 ℃ , taller even. The river valley fighting heat that lays eggs centrally because of turtle of foregone red river spot is in progenitive and seasonal temperature is extremely high, nearly always prep above of 35 ℃ . Reflect this level, is the temperature that Suzhou zoo installs when the hatch before this too low?
Now look back on, the mankind is as long as more than 10 years this to save the action of spot turtle, end in order to fail. The death of female turtle makes scientific research worker lost the chance of more understanding to spot turtle not only, the huge biology message that individual place carries the foregone female that puts only also can disappear subsequently. "Whole process is troubled by very tiredly, very anxious. " hear assist to feel very regretful, "The basic research that if we spend time of 10 years to make spot turtle ecology, genetics and field,protects place to need works, whether can ending differ? Whether can ending differ??
Do not come home directly " spot turtle girl "

Of course, this is the question that an appreciably is taking a mood. Nevertheless, steer clear of is the answer, have a doubt additionally, is that why " spot turtle girl " always return hard " a married woman's parents' home " ?
According to most initial original plan, turtle of female in September 2009 spot is about to return Changsha, but to continue to try, changsha zoo did not put forward to receive. On May 5, 2014, our newspaper also has reported " far marry Suzhou 6 years not spot turtle girl of many years old 80 answers pregnant this year long " , call Changsha zoology the zoo at that time (after Changsha zoo removed 2010 incognito) the decision is in receive female spot turtle before October in those days a Changsha.
But according to the spot turtle that signed in September 2007 cooperative breed considers to plan, this is protection of wild living things learns international (WCS) , international terrapin lives allied (TSA) with garden of two quake content the project of coact, again amid of Chinese zoo association is coordinated, can receive time be not one party to be able to decide.
Suzhou zoo respect is accepting the response when interviewing at that time: Did not receive Changsha respect at present any wanting that receive spot turtle the information that answer, although Changsha zoology zoo wants to receive,answer what also should organize through relevant section to agree, this is not an easy thing.
Of death " spot turtle girl " how will find a place for finally?
