Causes of Multiple Pregnancy
One of the causes of multiple pregnancies is IVF or in vitro fertilization. There are cases where there are two embryos that sit in the uterus, one from the IVF where a fertilized cell is transferred to the uterus, and the other by natural conception.
It has also been observed that women who are older than 35 are more likely to have multiple pregnancies. Older women have higher chances of releasing more than one egg cell during their cycle, which also increases the chances of multiple pregnancies.
At this point, doctors know little about the direct causes for identical and sesquizygotic twins. But there are a few conditions that increase the likelihood of multiple births.
Conditions for Multiple Pregnancies
The following conditions increase the chances of multiple births. But remember, there is no 100% guarantee that these will lead to twins:
- Women aged 30 and up need higher levels of estrogen to function, which increases the chance to produce and release more than 1 egg cell
- If there is a history of twins in the family, especially if the woman has a twin.
- If the previous pregnancy is twins, it has a higher chance to conceive twins in the next.
- Race affects the chances of having multiple pregnancies. African women have the highest and Asian women are the lowest chances of multiple pregnancies.
- Fertility treatment such as ovulation medications and IVF gives a higher chance for conceiving and multiple pregnancies.
Risks and Complications of Multiple Pregnancies
There are a lot of risks and complications during multiple pregnancies. Having one is already a stretch for a woman’s body. Make sure to consult your doctor regularly especially in cases of multiple pregnancies, to help you carry and deliver your baby safely.
