The chances decrease with age unlike natural twin conception , as women 38 to 40 only have a 5. And for those who are 43 and older, the rate is just 0. And consider this: Some couples may choose to transfer two embryos during IVF. Say one of those embryos splits and then all three implant in the uterus. The result would be triplets — two identical twins and one fraternal sibling. Women carrying twins are at an increased risk of developing preeclampsia and gestational diabetes.
It just means you may need to be monitored a bit more closely. But experts currently recommend younger women transfer just one embryo per IVF cycle for the best outcome. Ovulation-enhancing drugs used alone or with IUI require a prescription and may carry some serious risks, like higher chance of ovarian hyperstimulation or ectopic pregnancy. Drugs and procedures like IVF are also costly and typically reserved for couples who have been diagnosed with infertility.
For women under 35, infertility means not getting pregnant with timed intercourse in the course of a year. And for women over 35, this timeframe shortens to 6 months. They can tell you about any associated risks unique to you and if doing a multiple-embryo transfer with IVF might be an option.
There are certainly both risks and rewards with twins. But before you get too carried away with dreaming, try first looking forward to seeing double… with the lines on your pregnancy test.

One study estimated a woman can have around 15 pregnancies in a lifetime. And depending on how many babies she births for each pregnancy, she'd probably have around children. But the "most prolific mother ever," according to Guinness World Records, was Mrs. Feodor Vassilyev in 19th century Russia. She's said to have given birth to 69 children over 27 pregnancies.
It's a lot for a woman. But nothing compared to Moulay Ismail, for example. According to records, he had 4 wives and women in his harem. But, there are factors not even an emperor can control. Like how a man's sperm becomes less mobile and more abnormal as he grows older. The hurdles for ushering 69 children into the world hardly stop there, however. The winding down of a woman's "biological clock" makes a lot of sense from an evolutionary perspective, for carrying and delivering a child is an incredibly difficult task made harder with age.
The burden of labour is what really begins to undermine the credibility of Vassilyev's 69 children claim — especially considering the setting of hundreds of years ago, out in the Russian countryside. Multiple twins or triplets could in principle allow for high numbers of children, but the health risks are great Credit: SPL. In developed nations, modern obstetric care, such as medically necessary caesarean sections, has slashed maternal mortality rates.
In the UK, just eight women per , live births die due to pregnancy-related issues while pregnant or within six weeks of ending a pregnancy, according to the most recent statistics from the World Bank. Meanwhile, in one of the poorest countries on the planet, Sierra Leone, the rate is 1, maternal deaths per , live births. Assuming Mrs Vassilyev survived 27 labours is accordingly dubious.
Notably, the risks for serious, deadly complications, such as hemorrhaging, skyrocket with multiple births such as quads. Mrs Vassilyev's multiple conceptions of twins, triplets and quadruplets further strains credibility.
Fetal twins and their more numerous permutations come about in one of two ways: either multiple ovulated eggs are successfully fertilised by sperm — so-called fraternal twins — or a single fertilised egg divides into two or more viable embryos, leading to identical twins with the same genetic code.
Overall, these events are very rare. In the UK in , for instance, the chances of birthing twins stood at just 1. True, a propensity to have twins does run in families, so Feodor's wife could arguably have been just an extreme example. But overall, the odds for Mrs Vassilyev to have somehow conceived and then survived the cranking out of 16 twins alone — let alone the quads — seem astronomical. I'd be shocked," says Jonathan Tilly of Northeastern University, who is investigating oocyte stem cells for their use in infertility and women's health which we'll hear more about later on.
Modern fertilisation techniques mean births of countless children could, in theory, be possible Credit: SPL. Yet another red flag in the Vassilyev tale: supposedly 67 of those 69 children survived infancy. Infant mortality was high in the 18th Century for full-term singletons, and dismally more so for higher-order births, who are almost always born pre-term and less healthy.
Segars agrees. The last reason he doubts the Vassilyev claim? I couldn't imagine living in that house. If it were true after all, however, the daunting childcare duties could be part of the reason why after decades of marriage, the Vassilyev couple split up.
Old man Feodor took a second wife, who allegedly had "only" 18 children. Talk about tabloid fodder. A South African woman has reportedly given birth to 10 babies in what would be a new world record. Gosiame Thamara Sithole's husband says they were astonished by decuplets after scans only showed eight in the womb. I am happy. I am emotional. I can't talk much," her husband Teboho Tsotetsi told Pretoria News after the birth. One South African official confirmed the births to the BBC, however another said they were yet to see the babies.
A family member, who did not want to be identified, told the BBC that Ms Sithole had had 10 babies - five via natural birth and 5 via caesarean section.
A woman who had eight babies in the US in currently holds the Guinness World Record for the most children delivered at a single birth to survive.
