In an effort to further conservation exertion for the Asiatic elephant , veterinarians at the Smithsonian National Zoo have performed a series of contrived insemination procedure on Shanthi , a 34 - year erstwhile Asian elephant .
A successful pregnancy would be an important milepost in the zoo ’s commitment toAsian elephant conservation , zoo officials say in a command .
The National Zoo has performed a series of artificial insemination attempts to impregnate Shanthi the elephant.
For now , Scientists will monitor the grade of the hormone progesterone in Shanthi ’s blood . If concentration they find are elevate and stay that way of life for more than 10 weeks after insemination , it most likely would stand for she is significant . An Asian elephant ’s gestation period crop from 20 to 22 months .
In 2001 , Shanthi gave birth to Kandula . He was the fifth elephant in the world conceive by contrived insemination . Through past artificial insemination function do with Shanthi , menagerie scientist were able to build up a neat intellect of elephant reproduction . Zoo procreative physiologist Janine Brown discovered that elephants have what is called a double luteinizing internal secretion surge , which turned out to be life-sustaining for the proper timing of theartificial insemination .
This discovery was very utile , as artificially fecundate an elephant is a ambitious and hard medical procedure . The artificial insemination must be clock properly : Elephants have two rush of luteinizing internal secretion in about a three - week period . Using blood sampling , scientists are able to detect when the first surge occurs . The second luteinizing internal secretion upsurge follows about 20 days later , and that is when contrived insemination takes situation .
The National Zoo has performed a series of artificial insemination attempts to impregnate Shanthi the elephant.
Other agent for achiever include a sound reproductive pamphlet for the elephant . The semen used for the subprogram must also be of good lineament and must be placed correctly in the cervix and/or womb .
Artificial insemination has been used by zoological garden in other cases : In 2008 , a rhino at a zoo in England give birth to thefirst rhino calf successfully generated from stilted insemination .
An elephant birthing would bolster up thedecreasing population of Asian elephantsin North America and is an important step toward creating a multigenerational herd at the National Zoo . Zoo scientists have studied Asiatic elephants in the wild for more than 40 long time in an attempt to prevent their extinguishing . around 30,000 to 40,000 Asian elephants stay in the wild today .
