Can anyone have twins?
The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births. And while it may be obvious, identical twins are always the same sex, either both boys or both girls, at birth. Why? Well, they don’t just look alike — they also share the exact same DNA.
Do twins run in the family?
Non-identical (fraternal) twins tend to run in families. But identical twins don’t. Non-identical twins are the result of two separate eggs being fertilised by two separate sperm. If he has daughters, they may inherit the gene, and one day go on to have fraternal twins.
How do twins happen?
How twins are formed. Identical twins occur when a single fertilized egg splits into two. Fraternal twins occur when two, separate eggs are fertilized by two, separate sperm. Fraternal twins do not share the exact same genes — they are no more alike than they are to their siblings from different pregnancies.
What causes twin pregnancy?
Multiple pregnancy usually happens when more than one egg is fertilized by a man’s sperm. But it also can happen when one egg is fertilized and then splits into two or more embryos that grow into two or more babies. Twins are called identical when one fertilized egg splits into two.
Do you bleed more with twins?
5: Spotting may be more common during twin pregnancies. “When you spot in the first trimester, you could be undergoing a miscarriage, and miscarriages are more common in mothers of twins, triplets, and quadruplets — so we see more spotting in first trimester with multiples,” Al-Khan says.
Do twins develop slower in early pregnancy?
Multiples do tend to be born smaller than single babies. But it’s not because their growth rate is necessarily slower — in fact, for twins, it’s about the same as any other baby’s until about weeks 30 to 32, when they do slow down a tad, since they’re competing more for nutrients.
Can you get pregnant if your already pregnant?
In extremely rare cases, a woman can get pregnant while already pregnant. Normally, a pregnant woman’s ovaries temporarily stop releasing eggs. But in a rare phenomenon called superfetation, another egg is released, gets fertilized with sperm, and attaches to the wall of the uterus, resulting in two babies.
What happens if sperm goes inside during pregnancy?
Most of it will simply be discharged from the body through the vaginal opening. Thanks to the placenta, amniotic sac, and mucus plug covering the cervix, your baby has a protection system that’s very specific about what goes in and stays out!
