    Triplets for woman with two wombs

    A UK woman with two wombs is believed to be the first in the world with the condition to give birth to triplets.
    Hannah Kersey, 23, from Northam in Devon, had identical twins Ruby and Tilly, who were born from one womb, Grace, who was born from the other.
    The girls had to stay in hospital for nine weeks after being born seven weeks early by Caesarean, but have now returned home to their parents.
    The odds of having triplets from two wombs are about 25 million to one.

    The chances of a woman with two wombs having twins or two separate births is estimated to be five million to one.
    Against the odds
    Only 70 women in the world are known to have been pregnant in two wombs, reports suggest.
    The condition, which is actually called uterus didelphys, affects one in 1,000 women in the UK.
    In Miss Kersey's case, the babies were conceived from two eggs - one in each womb - which were fertilised at the same time by two different sperm.

    One egg then divided, producing identical twins, while the other developed into a single baby.
    Hannah and her partner Mick Faulkner said they were "over the moon" at how healthy and happy the girls are.
    Hannah said: "They are three lovely and incredible children, all with very different personalities.
    "Gracie seems to be the ringleader - maybe because she grew up in her own womb.
    "Ruby is very laid back and quiet, happy to sit and watch what is happening around her.

    Occur when the uterus fails to fuse normally during development
    Vary in severity - sometimes the division extends into the vagina
    Can cause fertility problems


    "Tilly, who was the baby that struggled to survive inside me, is a real fighter, wanting to keep up with her sisters and not be left out."
    Dr Simon Grant, a consultant at Southmead Hospital who delivered the babies, said: "There are very few world firsts nowadays, but it may be one."
    Mr Ellis Downes, consultant obstetrician and gynaecologist at Chase Farm Hospital in London, said: "It is quite amazing. Women with two wombs have conceived a baby in each womb before but never twins in one and a singleton in the other."
    Leading expert Mr Peter Bowen-Simpkins added: "For a woman to spontaneously conceive and give birth in this way is a real rarity. They have been extremely fortunate." Mr Richard Warren of the Royal College of Obstetricians and Gynaecologists said most cases occur naturally, but the condition can run in families. Hannah's mother and sister also have two wombs.

    Your numbers do not come close to adding up correctly.

    There are over 3 billion female humans on this earth.* Over 1 billion of them should be between 15 and 40 (child bearing age) . . . .

    Using your 'odds', there would be about 40 women in their child bearing years with triplets from this "first in the world" pregnancy (and about 80 women with triplets from this alive in the world today). Unless of course something had killed off the other women.

    Sounds like your news story is a couple cards short of a full deck.

    The way I read it was that if a woman has two wombs, the odds of having triplets from those two wombs is 25 million to one.

    I base this on the subsequent statement

    "The chances of a woman with two wombs having twins or two separate births is estimated to be five million to one."

    Different sets of statistics in the same article . . . . usually indicates a lack of understanding of statistics or the intent to lie.


    if then there are 70 with this condition and pregnancies in two wombs . . .

    Then: 70 * 5 million (one in five million) = 350 million . . .

    But, if you call Ronco right now . . . just look at what you will get:

    350 million times 1,000 (one in one thousand) = 350 billion (with a B).

    The article is misleading because the author(s) does not understand the data and the math, or the originators of the statistical data do not. Or, someone is lying to make a profit off of the sensational news.

    If the cop says that he is writing you a speeding ticket for 170 (100 miles an hour over the posted 60) instead of a ticket for 70 . . . you should immediately see the error is of at least a factor of 10 (10*10=100).

    The article was (most likely, IMHO) using 2 different sets of data (statistics) . . . and neither set of data was very 'clean' (accurate, IMHO).

    PS

    I did the math on both sets (yes there may be additional sets of data underlying what was given) very quickly - there is always a margin of error.

    But, since I cannot see what the real data was - I do not try to clean up dirty data - unless paid to do so. So down and dirty is all the research I will do on this thread.

    And say, congratulations to the poor young lady! She is probably more concerned with getting back to 'normal' life.
