Lion cubs born in Chile after reverse vasectomy on father


Two baby lion cubs were presented to the public at a zoo in Chile on Thursday, born after a pioneering veterinary procedure that involved a reversed vasectomy of their father.

The cubs’ mother ‘Masai’ became pregnant after the father ‘Maucho’ underwent the procedure, which vets at Buin Zoo in the suburbs of Santiago said took months of planning and a five-hour operation.

Both parents had been rescued from circuses.

‘This is the first successful reversal of a lion vasectomy reported in the world,’ said Marcelo Marconi, a urology specialist who joined the zoo vet team to lead the procedure. 

‘It gives a way of preserving and maintaining a species in a zoo.’

The procedure could be copied by other places around the world that have lions in captivity, the zoo said.

One of the cubs, which were born around three months ago, is named Niara and the other is yet to be named. Both are female

While the vasectomy reversal was purposefully done this time, the initial vasectomy procedure doesn’t always work, sometimes leading to surprising results.

A male lion named Brutus surprised a Cape Town sanctuary two years ago after parenting three ‘miracle cubs,’ despite having had a vasectomy in his youth.

The cubs were born to his partner Nala at Drakenstein Lion Park just before Christmas in 2015 – and, Brutus was sent back to the vet to have the snip a second time.

Park owner Paul Hart said: ‘We are a non-breeding sanctuary and Brutus before he became sexually mature had a vasectomy, which we assumed worked because for the last three years there has been no offspring.

‘So we were taken completely by surprise by the cubs.’

THE RARE MANED LIONESSES THAT ACT LIKE MALES 

Researchers have observed five lionesses at the Moremi Game Reserve in the Okavango delta that act like males, scent-marking at a similar frequency, and even mounting other females.

And, sporadic reports of other maned lionesses have been recorded over the years.

Researchers say high amounts of testosterone could be to blame for this phenomenon, according to New Scientist.

It’s known that the hormone is directly tied to the development of the mane – in the case that a male is castrated, he will lose his mane.

And, a female lion held at the National Zoological Gardens of South Africa was found to develop a mane after problems in her ovaries resulted in an increase in testosterone.

Once the issue had been resolved, the mane disappeared.

Hart added: ‘Hopefully, this time round, we’ll fix the problem.’

The unusual course of events was referred to as a ‘Christmas miracle’ or ‘White Christmas’ as the parents – and now the cubs – are rare white lions due to an unusual genetic mutation. 

The Drakenstein Lion Park is a private sanctuary that rescues captive lions from abusive environments that cannot be released into the wild.
