How are twins conceived?

Vanessa

I know that once the sperm enters the egg no other sperm can get in but how our twins concieved is two eggs.

Answer
There are two types of twins -- monozygotic (usually called "identical") and dizygotic (called "fraternal"). It sounds like your twins are dizygotic: two of your eggs matured and were released by your Fallopian tubes, then were fertilized by two separate sperm. These fertilized eggs developed into two embryos. Because the twins result from separate pairs of egg and sperm, they will not be identical.

FYI -- monozygotic twins occur when a single zygote (fertilized egg) splits after fertilization. Because the twins come from the same egg and sperm, they will be identical (have the same genetic makeup).

A rare case of monozygotic twins are "polar twins," which occur when a single egg splits in two and the two halves are fertilized by two separate sperm. These twins share identical DNA from the mother, but since the two sperm are different, they will not be identical -- although they will be more genetically similar than fraternal twins.

I want to conceive twins!?

Ireland

did you conceive twins and did you do anything special?
I heard that if you double up on iron and folic acid you are more likely to conceive twins. I read this on a medical web site.
for one thing, twins do run in my family.... and for another, you can choose the sex of your baby. Its all determined by the position you have sex in, whether you have an orgasm or not, and a specific vitamin cocktail. it worked for me.

Answer
You don't just conceive twins . . . some women are at a higher risk for twins due to a gene that causes them to ovulate more than one egg. This is usually a family trait on the mother's side.

Outside of that, women over 35, overweight and/or women with a diet high in yams and/or dairy for whatever reason have a higher CHANCE for twins.

Fertility treatments also put you at a higher risk for twins . . . overall, 3% of all births are a multiple birth, There are things that may increase your chances but there are no guarantees.

I was blessed with twins after going through IVF - we transferred 2 embryos and lucked out when both stuck . . . it was a long painful, stressful experience having to go through infertility . . . but in the end, we truly were lucky but having to deal with an inability to conceive on your own, medications, injections, side effects etc . . . is not the ideal way to have children.

Good luck!

What is the best way to conceive twins?

how to get conceive for twins image

Q. I've wanted twins since I was a very little girl, and I don't want to get pregnant unless I have twins. Is there some way I can know if I can conceive twins?
Twins in my family skip three generations, and I am the third generation. I guess that's why I'm so bent on having twins.
What is ttc?

Answer
yams and lots of em for up to 2 years before ttc and just keep eating them .. there is a tribe that's main staple diet is yams and they have 80% twins.. good luck ..

No one is quite sure why, but the Yoruba tribe in West Africa has the highest rate of twinning in the world. A study concluded that the mother's diet was the cause, being high in cassava, a type of yam or sweet potato. The peelings of this vegetable are thought to contain a chemical that causes hyperovulation. In addition, a 2006 study found that women who consume dairy are five times as likely to have twins.

1) Have a History
Do twins run in your family? If you have a mother, brother, sister, uncle or long lost cousin with multiples, you may wonder if you'll have them too. Sometimes twinning is hereditary, it's true. However, only fraternal (dizygotic twins are influenced by heredity, and then only in some cases. If your mother or maternal grandmother was or had fraternal twins, you might have inherited a gene for hyperovulation, increasing your chances of conceiving twins also.

Grow or Gain Weight
A recent study published by the American College of Obstetrics and Gynecology correlates the rise in multiple birth rates with rising rates of obesity. Research found that mothers with a BMI (Body Mass Index) of 30 or higer were significantly more likely to have twins. Again, this statistic only holds true for fraternal (dizygotic) twins. The research also showed that women of above-average height were also more likely to have multiples.

3) Wait Until You're Older
Older mothers are more likely to conceive twins than their younger counterparts. It's thought that the body accelerates ovulation as the biological clock starts ticking faster. Seventeen percent of mothers over age 45 have multiples. Wait five more years and the odds rise to one in nine!

4) Have More Twins
Once you have had a multiple pregnancy, you are significantly more likely to conceive -- and deliver -- twins again! Some estimates suggest that mothers of twins are four times more likely to have twins again than a woman who has never been pregnant, or who only had a singleton.


6) Seek Fertility Assistance
Reproductive technology has dramatically increased the multiple birth rate. Drugs that stimualate ovulation can lead to a multiple pregnancy, but multiples can also result from invitro fertilization. It's not just that multiple embryos are implanted in the mother, but there is also an unexplained increase in the number of monozygotic twins among IVF patients. No ethical doctor would provide treatment if it wasn't warranted, so fertility assistance should only be sought out when necessary.


7) Have A Big Family
The more kids you have, the more likely you are to conceive twins in a subsequent pregnancy. No one knows the magic limit that triggers a multiple pregnancy, so you'll just have to keep trying until it happens.

Most people think that you can't get pregnant while breastfeeding, that the process of lactating keeps a woman from ovulating. However, plenty of mothers of twins can disprove that theory. Some research has supported the theory that the chance of twins or multiples is increased if a woman conceives while breastfeeding

9) Get Pregnant On the Pill
Birth control pills are usually thought to be 99.9 percent effective at preventing pregnancy. However, that .01 percent often results in a double whammy -- multiples. Sometimes pregnancy occurs when the pill isn't taken consistently; in other cases, the hormonal mix of a particular drug type simply doesn't provide enough coverage to completely prevent ovulation. In either case, playing around with hormones can lead to hyperovulation, increasing the chances of multiples.

10) Just Get Lucky!
Many parents of multiples don't meet any of the classic criteria, yet find themselves doubly blessed. Monozygotic twins are particularly mysterious; no one is exactly certain what causes an egg to split after conception, producing identical twins. The bottom line is that there truly isn't a whole lot an individual can do to influence their chances of having twins; sometimes you just get lucky!
