Factors that increase the chance of twins include: consuming high amounts of dairy foods, being over the age of 30, and conceiving while breastfeeding. Many fertility drugs including Clomid, Gonal-F, and Follistim also increase the odds of a twin pregnancy.
Although certain factors increase the chance of having twins, there is no way to improve the odds of having twins naturally. A woman will usually find out that she is pregnant with twins from an ultrasound early on in the pregnancy.
Number of previous pregnancies – the greater the number of pregnancies a woman has already had, the higher her odds of conceiving twins. Heredity – a woman is more likely to conceive fraternal twins if she is a fraternal twin, has already had fraternal twins, or has siblings who are fraternal twins.
Hyperovulation-stimulating foods: There are a few foods that naturally increase the rate of ovulation and stimulate ovaries to release multiple eggs. Such hyperovulation stimulating foods include cassava (an African wild yam or sweet potato), tofu, soy isoflavones, whole grains, and whole wheat.
The quick answer to this question is that, in a twin pregnancy, it is the mother's genes that determine twins. First up, giving birth to identical twins is not genetic, but conceiving fraternal twins is. The mother may have the genetic trait of releasing two eggs in one menstrual cycle.
Multiple pregnancy usually happens when more than one egg is fertilized. It also can happen when one egg is fertilized and then splits into 2 or more embryos that grow into 2 or more babies. When one fertilized egg splits into 2, the babies are called identical twins.
Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families. But there are some factors that make having non-identical twins more likely: non-identical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese.
Being pregnant with multiples doesn't necessarily mean that your pregnancy will be problematic. However, women carrying multiples do have a higher chance of developing complications such as high blood pressure and preterm labor. For this reason, all multiple pregnancies are considered high-risk.
Identical twins are almost always the same sex, although there are some rare exceptions to this rule. Because identical twins occur when a single fertilized egg splits and forms two embryos, each embryo has the same chromosomes (usually, XX for girls or XY for boys).
Taking fertility medication is one of the most common ways to get pregnant with twins. They increase fertility by stimulating egg production. If more eggs are produced, the chances that more than one egg will be released during ovulation also increase.
Some females may produce more FSH (follicle-stimulating hormone) in the body. So more than one follicle can become dominant, resulting in the release of more than one egg. Females having a family history of multiple pregnancies have a greater chance of getting pregnant with more than one baby at once.
The folic acid dose of 1000 µg per day for women with a twin pregnancy is also recommended by Goodnight et al.
Because women in their late 30s and 40s have a higher percentage of abnormal eggs, it's much more likely that their one egg each month will be abnormal. That's why natural fertility declines with age, and why we see infertility, miscarriage, and genetic disorders more often with women over 35.
-Take a glass bowl or jar filled with water. -Then dip the egg into the water. If the egg is placed at the bottom of the glass width wise, then the egg is absolutely fresh and fit to eat. -In case the eggs are stale or a bit old, it will be placed at the bottom on one end of the glass.
Other than age, causes such as endometriosis, ovarian cysts, some immunological disorders, obesity, chemotherapy, drug use, smoking, alcohol and caffeine consumption may also lead to decreased egg quality.
However, only women ovulate. So, the mother's genes control this and the fathers don't. This is why having a background of twins in the family matters only if it is on the mother's side. And why your son's family genetics did not play a role in his twins.
Yes, some types of twins are hereditary, meaning that twins run in families. Heredity on the mother's side ups a couple's odds of conceiving fraternal twins. Fraternal twins are two babies from two different eggs that were released from the ovaries simultaneously.
The likelihood of conceiving twins is a complex trait, meaning that it is affected by multiple genetic and environmental factors, depending on the type of twins. The two types of twins are classified as monozygotic and dizygotic.
