Proud parents Denise and Glen Higgs never thought they would be able to have children after he was made infertile due to cancer treatment.
But using his frozen sperm, doctors successfully created eight embryos through IVF and the couple had a daughter Mazy, born three years ago.
The couple tried again using the same batch and Denise gave birth to twins Carter and Carson last week.
Former RAF fireman Glen, of Braunton, Devon, said: “Medical staff have told us our three children are triplets as they are all from the batch of embryos that were created at the same time.
“It is crazy really – seeing as there are three-and-half years between them in age.”
Glen, 35, had always wanted to have children and decided to store sperm shortly before his testicular cancer treatment at the age of 20 made him infertile.
He met Dee and, after living together for five years, tied the knot in 2011 before embarking on a course of IVF treatment.
Glen said: “I had an unusual tumour growing within the testicle. After all my treatment, they tested my sperm and they were non-swimmers.
“I knew then that if I ever wanted to have children I would have to go through IVF.
“I had always wanted kids and first went through the process with Dee in 2010. We got funding for the first try and got lucky when Mazy was born.”
Glen, now a manager at a filter-making factory, said: “We then just had to wait and see if it attaches ok. We ended up having eight embryos.
“We put two in to attempt to have a child the first time and froze the other six.
“We were talking about getting rid of them – as we were paying a yearly storage fee – but decided to try again. We had to fund it ourselves this time and put two in again.
“Amazingly they both stuck and we have ended up with two more beautiful babies.
“I always wanted to have kids and am a big family man. The process we went through was hard but we could not have asked more from the final outcome.
“I am the happiest man ever. I have three healthy kids when I thought I would never have any. One we thought would be amazing – to have three is an unbelievable gift.
“What my wife and her body had to go through makes her the real hero to me.”
The IVF procedure involved doctors effectively “hoovering” the eggs out of Dee’s body and injecting them with the frozen sperm.
Care assistant Denise, 27, said: “When I heard I was having twins I cried and my husband just went white. To now have triplets is simply amazing.
“We were so happy though. It has been a huge change in our lives but we have just learnt to adapt.
“Going through IVF is one of the hardest things you ever have to go through as a woman.
“The whole process is horrendous, but as we have proved it does actually work.
“There are so many injections and medication and it can be very undignified at times. I did get very emotional at times but I have no regrets at all about doing it.
“I could not be happier with what we have been left with.”
The couple have now disposed of the remaining embryos and have no plans to have any more children.
