Scientists have cleared a significant hurdle in the years-long effort to save Africa’s northern white rhinoceros from extinction with the first-ever rhino pregnancy using in vitro fertilization.
The lab-assisted pregnancy, which researchers will announce today, involved implanting a southern white rhino embryo in a surrogate mother named Curra.
The advance provides the essential “proof of concept” that this strategy could help other rhinos, says Jan Stejskal of the BioRescue project, the international group of scientists leading this research.
Curra died just a couple months into her 16-month pregnancy from an unrelated bacterial infection, Stejskal says.
However, the successful embryo transfer and early stages of pregnancy pave the way for next applying the technique to the critically endangered northern white rhino.
The process was documented exclusively by National Geographic for an upcoming Explorer special currently slated to air in 2025 on Nat Geo and Disney+.
BioRescue expects to soon implant a northern white rhino embryo into a southern white rhino surrogate mother.
The two subspecies are similar enough, according to the researchers, that the embryo will be likely to develop.
Eventually, this approach may also help other critically endangered rhinos, including the Asian Javan rhinoceros and the Sumatran rhinoceros, which each now number under 100 individuals, Stejskal says.
But the northern white rhino’s current situation is the most pressing by far.
There are no males left, and the only two remaining animals are both elderly females that live under armed guard on a reserve in a 700-acre enclosure in Kenya called Ol Pejeta Conservancy.
The boxy-jawed animals once roamed across central Africa, but in recent decades, their numbers have plummeted due to the overwhelming international demand for their horn, a substance used for unproved medicinal applications and carvings.
Made from the same substance as fingernails, rhino horn is in demand from all species, yet the northern white rhino has been particularly hard-hit.
"These rhinos look prehistoric, and they had survived for millions of years, but they couldn’t survive us,” says Ami Vitale, a National Geographic Explorer and photographer who has been documenting scientists’ efforts to help the animals since 2009.
“If there is some hope of recovery within the northern white rhino gene pool — even though it’s a substantially smaller sample of what there was — we haven’t lost them,” says conservation ecologist David Balfour, who chairs the International Union for the Conservation of Nature’s African rhino specialist group.
Blueprints for rhino babies
To stave off the animal’s disappearance, BioRescue has used preserved sperm from northern white rhinos and eggs removed from the younger of the two remaining females.
So far, they’ve created about 30 preserved embryos, says Thomas Hildebrandt, the head scientist of BioRescue and an expert in wildlife reproduction based at the Leibniz-Institute of Zoo and Wildlife Research in Berlin.
Eventually, the team plans to reintroduce northern white rhinos into the wild within their range countries.
“That’d be fantastic, but really, really far from now—decades from now,” says Stejskal.
Worldwide, there are five species of rhinoceros, and many are in trouble.
Across all of Africa, there are now only about 23,000 of the animals, and almost 17,000 of them are southern whites.
Then there are more than 6,000 black rhinos, which are slightly smaller animals whose three subspecies are critically endangered.
In Asia, beyond the critically endangered Javan and Sumatran rhinos, there’s also the greater one-horned rhino, whose numbers are increasing and currently are estimated to be around 2,000.
The BioRescue effort has experienced many setbacks, and even though the team now has frozen embryos, the clock is ticking.
The researchers intend to use southern white rhinos as surrogate moms for the northern white rhino embryos.
However, scientists want any northern white rhino calves to meet and learn from others of their kind, which means they need to be born before the two remaining females die.
“These animals learn behaviors — they don’t have them genetically hard-wired,” says Balfour, who’s not involved with the BioRescue work.
But birthing new animals in time will be a challenge.
“We’re really skating on the edge of what’s possible,” he says, “but it’s worth trying.”
Najin, the older female, will be 35 this year, and Fatu will be 24.
The animals, which were born in a zoo in the Czech Republic, are expected to live to about 40, says Stejskal, who also serves as director of international projects at the Safari Park Dvůr Králové, the zoo where the animals lived until they were brought to Kenya in 2009.
Impregnating a rhino
The next phase of BioRescue’s plan involves implanting one of their limited number of northern white rhino embryos into a southern white rhino surrogate mother — which the group plans to do within the next six months, Stejskal says.
They’ve identified the next surrogate mother and set up precautions to protect her from bacterial infections, including a new enclosure and protocols about disinfecting workers’ boots.
But now, they must wait until the female rhino is in estrus — the period when the animal is ready to mate — to implant the egg.
To identify that prime fertile time, they can’t readily perform regular ultrasounds at the conservancy as they might do in a zoo.
Instead, they have enlisted a rhino bull that has been sterilized to act as a “teaser” for the female, Hildebrandt says, adding that they must wait a few months to make sure that their recently sterilized male is truly free of residual sperm.
Once the animals are brought together, their couplings will alert conservancy staff that the timing is right for reproductive success.
The sex act is also important because it sets off an essential chain of events in the female’s body that boosts the chances of success when they surgically implant the embryo about a week later.
"There’s little chance the conservancy staff will miss the act. White rhinos typically mate for 90 minutes," Hildebrandt says.
What’s more, while mounted on the females, the males often use their temporary height to reach tasty plant snacks that are generally out of reach.
Boosting genetic diversity
With so few northern white rhinos left, their genetic viability may seem uncertain.
But the BioRescue team points to southern white rhinos, whose numbers likely dropped to less than 100, and perhaps even as few as 20, due to hunting in the late 1800s.
Government protections and intense conservation strategies allowed them to bounce back, and now there are almost 17,000.
“They have sufficient diversity to cope with a wide range of conditions,” says Balfour.
Researchers don’t know exactly how many southern white rhinos existed a century ago, he says, but it’s clear that the animals came back from an incredibly low population count and that they now appear healthy.
Beyond their small collection of embryos, the BioRescue team hopes to expand the northern white rhino’s gene pool by drawing from an unconventional source — skin cells extracted from preserved tissue samples that are currently stored at zoos.
They aim to use stem cell techniques to reengineer those cells and develop them into sex cells, building off similar work in lab mice.
According to their plan, those lab-engineered sex cells would then be combined with natural sperm and eggs to make embryos, and from there, the embryos would be implanted into southern white rhino surrogate mothers.
Such stem cell reprogramming work has previously led to healthy offspring in lab mice, Hildebrandt says, but rhinos aren’t as well-studied and understood as mice, making this work significantly challenging.
A global effort
The northern white rhino revitalization venture has cost millions of dollars, supported by a range of public and private donors, including the German Federal Ministry of Education and Research.
Other partners on the effort include the Leibniz Institute for Zoo and Wildlife Research, the Czech Republic’s Safari Park, Kenya Wildlife Service, Ol Pejeta Conservancy, and also Katsuhiko Hayashi, a professor of genome biology at Osaka University in Japan who conducted the mouse stem cell research.
Building upon Hayashi’s stem cell techniques could ultimately bring the northern white rhino gene pool up to 12 animals — including eggs from eight females and the semen of four bulls, according to Stejskal.
An alternative approach to making more babies, like crossbreeding northern and southern white rhinos, would mean the resulting calves wouldn’t be genetically pure northern white rhinos, Hildebrandt notes.
The two subspecies look quite similar, but the northern version has subtle physical differences, including hairier ears and feet that are better suited to its swampy habitat.
The two animals also have different genes that may provide disease resiliency or other benefits, Hildebrandt says.
There are unknown potential differences in behavior and ecological impact when populating the area with southern white rhinos or cross-bred animals.
"The northern white rhino is on the brink of extinction really only due to human greed,” Stejskal says.
“We are in a situation where saving them is at our fingertips, so I think we have a responsibility to try.”

the problem with just now consuming older media is that I CANNOT interact with it online until i finish bc nobody thinks to tag spoilers for an anime that finished shortly before I turned five
#to be clear that's fine!!#i do not expect people to tag spoilers on that kind of thing#it is my job to not get spoiled and the way i do that is by NOT googling “kakashi big naturals”#...i make the ivf baby do it since he's seen all of it and then he shows me non spoiler images

but I really think that they are going to get married and have cute fat babies // they may get married, but they sure won't have babies. Max doesn't want to have kids anytime soon and Kelly's time is running out to make any.
she is 33, not 53. I know some of you love to hate women and will use any excuse to hate on her, but women have babies in their 40s, AND there are so many options available to them as rich people lmao
#asks#chit chat#Anonymous#these comments about how 'she can't have any cause her time is running out' is sooooo fucked lmao#surrogacy egg freezing ivf also natural pregnancies at over 40#read a book. go back to school.#your source of info should not be tumblr#wags#my best friends mom had a kid at 45 naturally lol.#baby chats

Do ruts and heats start to taper off as the person gets older? Or is there a 96 year old omega waking up in a full heat and groaning about the supposed joys of retirement.
they do! menopause for period havers occurs earlier (40s to 50s) while omega menopause happens on average in the mid-60s. ruts decline much slower over a longer period, losing potency and length to the point that if someone is that old and still working they could pass on their rut leave if desired (and if their place of work deems it acceptable; some careers have strict policies particularly if the employee in question works with the public or vulnerable parties). given the extended downswing, ruts are harder to give an accurate range for, however it's typical for ruts to cease entirely by the time the person in question is 80.
#asks#anon#mgv#thank you for good worldbuilding question#i was thinking about this the other day in passing ngl#also to note: natural pregnancy in postmenopausal omegas do not occur but they are still capable of carrying pups thru IVF#and alphas can still have pups no matter what the ruts just make it more likely a coupling results in pregnancy#still. pupping when you're older carries risks so while possible it is discouraged

Really funny niche to have in the friend group is "the only one who is dead-set on having kids". no one understands when im high and i start crying about having baby fever
#tbh im genuinely very scared about the possibility i may never have children#being in a same-sex relationship n all. we can't exactly get pregnant the natural way#and. mentally ill disabled queer stoner isn't exactly the most appealing adoptive parent#and ivf is expensive and scary...#waaaaah ..... behbehs...

Cora: “So, you mentioned kids back in Mount Komorebi.”
Avalon: “Yeah, sorry if it’s too soon.”
Cora: “No- I want to have kids too! I just thought we should talk about things. First, who do you think should carry them?”
Avalon: “Well, I’ve always wanted to go through pregnancy and all. I feel like it should be me.”
Cora: “Honestly I agree, plus I’m an astronaut, being pregnant would make that hard.”
Avalon: “Ha, yeah! So...what do you think, tomorrow we head to the doctor and get our fertility checked?”
Cora: “I’m in.”
#btw they wouldn't do ivf#they'll have the kids naturally so cora will be the other parent#hey its the sims anything can happen#sims 4#ts4#sims 4 gameplay#ts4 not so berry#nsb3#Cora Berry#avalon lee

During the IVF process, multiple eggs are harvested and fertilized, leading to the development of viable embryos, which are transferred to the uterus. In your IVF process, you need the mots critical decision for yourself whether you need to opt for single embryo transfer (SET) or multiple embryo transfer (MET). This article will provide you with information about the distinction between each approach, as both are associated with different risks and benefits. Your choice will directly impact the outcome of the IVF cycle and the long-term health of both the child and mother.

finished men have called her crazy by amt
eh
#honestly it was underwhelming#it’s a very white feminist read#she directs all of her fame and energy to the one group that is above her on the totem pole#and like ignores opportunities to lift up like 900 marginalized communities under her lol#like sure ur doctor sucks and didn’t listen#but rather than focusing 100% of the effort on the fact that he was a man#why not talk about how the medical system fails mental health patients#and there’s not enough research done to be able to accurately diagnose patients in a psych ward#why not spend more time talking about the prohibitive expenses of IVF and reproductive health care#and what that means for queer ppl who can’t have a natural birth#like a lot of her experiences could have been spun to address wider issues#but she just talks about how she hates men the whole time#idk I really wanted to like the book and her#and a lot of the points she made are valid and I would still like to go for a drink with her#but idt she really did the work on herself she claimed she did… like she doesn’t sound like a 40 yo woman in this book
